Newer versions

 

Please find the current Layer2 Cloud Connector Release Notes News Feed here for subscription.

 

 

Version 5.0.21.5 (outdated)

 

Fixes:

 

  • When creating folders in SharePoint libraries, an error occurred stating that the property "CheckOutType" has not been loaded. "The property or field 'CheckOutType' has not been initialized..."

Changes:

 

  • Optimized error handling and reporting for unexpected Windows Service termination.

 

Version 5.0.21.3

 

Fixes:

 

  • When accessing SharePoint libraries with versioning enabled and no enforced checkout, one upload has created four different new versions. This could lead to unexpected quota exceedance and issues with workflows and notifications. Now two new versions are created, one for the file upload and one for the metadata updates. Due to limitations with CSOM it is still not possible to create one new version only.
  • In some cases while updating data on SharePoint a NullReferenceException was triggered.
  • The settings of the FILENAME filter of the File System Provider included filtering of directory names. Now directory names are no longer filtered.
  • The Odata Provider created an error when a value could not bee parsed. This has been replaced with a warning and using of the default value.
  • Creating appointments on Microsoft Exchange Server 2007 could result in an error about the StartTimeZone-field not being loaded.

Changes: 

 

  • Pro Edition now allows Enterprise Edition features starting with January 2015. Customers with Pro Edition and valid Software Assurance have a free upgrade option.
  • If SharePoint returns a "Request too big" error, the current server objects will be loaded and updated one by one automatically.

 

Version 5.0.21.0

 

Fixes:

  • Minor memory leaks fixed. 
  • The log view in the Connection Manager is now refreshing during a synchronization run. 
  • Shareware restrictions have been adjusted.

Version 5.0.19.5

 

New:

  • The default log configuration now contains examples to use Windows Event Log instead of file log and send email alerts in case of issues.

Fixes:

  • Layer2 Data Provider for Exchange: When reading appointments in some cases the Exchange Web Service would return the error "The recurrence pattern’s FirstDayOfWeek property must be specified".

Changes:

  • When Exchange returns with a ErrorInternalServerTransientError, the Layer2 Exchange Data Provider will automatically retry to load the remaining items.

 

Version 5.0.19.3

 

Fixes:

  • The "Email" connection-string parameter for mailbox-impersonation has not been recognized. Now fixed. 
    • Changes:

     

    • It is no longer possible to have two different versions of the Cloud Connector installed side-by-side. If setup encounters another edition of the Cloud Connector, it will automatically be uninstalled prior to the installation.
    • When executing the Cloud Connector setup for .NET 4.5 on a System which does not support running the Microsoft Management Console in CLR 4, the setup will show an error message stating that the .NET 3.5 edition of the Cloud Connector needs to be installed. This is applicable for Windows 7 / Windows-Server 2008 RC2 or older.
    • The SharePoint fields fAllDayEvent and fRecurrence are no longer marked as unsupported fields. That means the fields can be used e.g. for SharePoint to SharePoint or SQL to SharePoint connections. Exchange to SharePoint is still not supported.

     

    Version 5.0

     

    • Layer2 Data Provider for Microsoft Exchange added to connect and sync Microsoft Exchange 2007 / 2010 / 2013 on-premises or Exchange Online contacts, tasks, calendar events, notes, email with SharePoint and almost any other data sources.

    • Updgrade from V4 to V5 requires a new license file. It's free for all customers with current Software Assurance (SA). Please contact sales@layer2solutions.com to request the license change before installation. You can simply use installer to upgrade. All data and settings are kept.

Version 4.8.0.2

 

  • Issues with the calculated field CCConnectionName and CCEntityName and specific providers like OData fixed.

 

Version 4.8.0.1

 

New:

  • Additional authentication method supported for Office 365 federated via RM Unify. Please use "Authentication=RMUnify" in connection string. RM Education Ltd. is one of the leading suppliers of ICT to UK education. More about RM Unify see here.

Change:

Fix:

  • Error message regarding file path exceeding max Uri length now shows the full path used for these calculations.
  • Number and Decimal conversions with DBNull values should now work as expected.

 

Version 4.7.2.3

 

New:

  • Microsoft Dynamics CRM authentication worked for Dynamics CRM Online only when using "company.crm4.dynamics.com" URL´s (EMEA). Now also implemented for "company.crm.dynamics.com" (North America) and "company.crm5.dynamics.com" (APAC).

 

Version 4.7.2

 

New:

  • During update now an estimation of the remaining synchronization time is shown.


Fixes:

  • Authentication-caching could in some cases lead to invalid cached cookies.
  • If a value was synchronized to SharePoint which was identical to the default value of the target SharePoint-field, it has not been written, which resulted in unexpected empty fields.
  • If an error occured during the schema-creation of a table, a subsequent error was triggered complaining about a duplicate field.

Version 4.6.10.1

 

New:

  • ADFS is now fully supported for Microsoft Dynamics CRM (on-premises and cloud-based).
  • The connection name and data entity name are now populated as additional fields CCConnectionName and CCDataEntityName automatically for all providers. The new features provides better management of data aggregations and multiple connections to the same list.

Change:

  • Files that do not match the naming requirements of the target system will no longer be treated as an error. Instead of an error a warning will be logged and the files will be skipped. That will make it a lot more easy to start syncing file shares and home drives with SharePoint.
  • Advanced character support for document names was added as currently supported for SharePoint 2013. (e.g. & Char). Was for SharePoint 2010 only before.
  • Error messages have been optimized for better understanding.
  • The SharePoint system fields Modified and Created will no longer be included in the auto-mapping. Mapping this fields can be helpful to keep file system metadata for SharePoint. But writing to those kind of system fields requires specific rights and can cause sync issues in some cases. As a best practice approach please make use of any additional date / time fields on the SharePoint side, e.g. FSModified, FSCreated and map manually.

Fixes:

  • Exchange sample connection had ExchangeID as the primary key which did not work in all cases. Now removed. Please leave blank in any case.
  • During synchronization of file system with SharePoint in some cases a "Null reference exception" error did come up. Fixed now.
  • The precondition checks of the SharePoint-Provider will now allow all the characters which are allowed on SharePoint Online (Some of the SharePoint file naming restrictions have been relaxed opposed to on-premise SharePoint).
  • In some cases after a CloudConnector upgrade, the providers have not been registered properly anymore. Fixed now.
  • On Windows Server 2008 R2 systems the providers have not been registered properly. Fixed now.
  • Bi-directional file synchronizations needed two runs to be in-sync in some cases. Fixed now.

New:

  • Microsoft OneDrive For Business is now fully supported, including the default library.
  • Basic support for SharePoint Managed Metadata Fields (read / write). The field content must fit to be applied as metadata. More advanced support will come soon.

  • If an internal field name was truncated by SharePoint, a warning that the CloudConnector creates led to an index-error. Now fixed.
  • Disabled operations now managed properly without instructing entities to perform disabled operations and without unexpected error messages.
  • When reading empty fields through the Odata-Provider, an Exception about DBNull could come up. Now fixed.
  • An error in metabase version migration could in some cases lead to an "Invalid cast"-exception. Now fixed.
  • File paths exceeding 128 characters could lead to an "Invalid argument parameters.FileLeaf" SharePoint exception. Now fixed.
  • Object reference issue on creating new items under specific conditions in 4.6.5 fixed in 4.6.5.1

Changes:

  • Performance optimations for file synchronizations. Folders now are cached. Sync performance improved.

Otherwise these fields will be managed as read-only. Several issues with recurring updates related to the modified date have been fixed with this release.
  • When the 32-bit version was installed on a 64-bit system, the background service was still running as a 64-bit process, which made 32-bit providers inaccessible. Fixed now.
  • In some views of the Connection Manager scroll bars did not appear when needed or in some cases appeared unnecessarily. Fixed now.
  • Creating files with the same name on both sides of a file synchronization connection led to a primary key error. It is now managed by the conflict resolution.

  • Occasionally there was an error "DataTable already belongs to another DataSet" coming up during synchronizations.


     

    Version 4.3.11

      

    Changes:

     

    • The Office 365 ADFS Authentication has been adjusted due to the changes that have been made in the Identity Service by Microsoft with the ongoing maintenance IS2992.

    • The Cookie Manager does not show an expiry date for session cookies anymore. Instead they will be denoted as session cookies with the creation date information. Also a cookie refresh will now always explicitly refresh the cookie and therefore prompt for credentials.
    • Live log optimization: The live log displays more detailed information in a more intuitive manner.
    • System logs will no longer contain connection specific log-messages. All connection specific logs go to the connection log now.
    • The current implementation of the abort-function is unstable and can result in various error conditions. (e.g. "No row for role right") The button is removed temporarily and will be re-implemented in one of the next releases.

    Fixes:

    • Verifying a SharePoint data entity caused a full load of the SharePoint-list which made the verify function useless for large lists.
    • The counts of operations in the live log have been inaccurate in some cases.
    • Errors often appeared twice in the logs.
    • If an error occurs during synchronization of a record, the error is added to the log and the record  will be skipped. After more than 10 consecutive errors, synchronization will be aborted with an error.
    • Deleting all items in a SharePoint list with the connection manager open, could lead to a "Index out of range" error on the next run.

    • In some cases new SharePoint documents have not been recognized before restarting the connection manager.
    • When uploading large files, in some cases an Out-Of-Memory Exception was thrown.

    Changes:

    • The number of history items on disk and in memory is now limited to 10. Existing histories will be truncated accordingly.
    • If the execution of a connection fails, it will not be scheduled for the next service run (1 minute later), but according to the configured synchronization interval.
    • The Cookie Manager does not show an expiry date for session cookies anymore. Instead they will be denoted as session cookies with the creation date information. Also a cookie-refresh will now always explicitly refresh the cookie and therefore prompt for credentials.

  • A new API folder is provided with sample source code to help users to develop their own ADO providers for Cloud Connector.
  • Auto mapped fields are now displayed in GUI to have more information about default field mapping.
  • GUI synchronization messages can now be copied, to send to support.
  • Additional FilenameFilter connection string parameter for the file system provider allows to filter files by using search patterns like "*.pdf"
  • The file system provider offers an additional column FilePathCopy which holds the file's path to map to some data destination column for additional information about data item source.

Fixes:

  • While writing against OData sources with protocol version 2.0 using Layer2.Odata.Provider, you have got "Request version '1.0' is not supported for the request payload. The only supported version is '2.0'. " This issue was fixed.
  • Sometimes wrong execution time displayed in log entry. This issue was fixed.
  • Delete/Update conflicts are now better detected and solved according to the configured conflict resolution on the connection level.

Known issues:

  • The OData provider gets first page of data only from Microsoft CRM. That will be fixed in further releases.
  • Multiple document versions can be generated during a single synchronisation (SharePoint on premise, SharePoint online) to fetch metadata. 

 

Version 3.1.3

 

Fixes:

  • While saving global configuration changes 'Could not load file or assembly 'SmartAssembly.Attributes, Version=4.1.0.0. An exception was thrown and changes were not saved. This issue is fixed.

  • If no mappings are provided, empty list items are created. This issue is fixed. Empty mappings are not allowed in connections anymore.
  • In GUI synchronization status messages about amount of changes not always were correct. This issue is fixed.
  • Synchronization progress bar oscillates. This issue is fixed.
  • When the firstDate connection attribute could not be parsed (mostly different locale issues), a format exception was thrown and the Cloud Connector MMC snap-in was not loaded. This issue is fixed. Connections with wrong datetime format added to the invalid connections list now. You can correct the connection file manually (e.g. remove attribute).
  • Automatically mapped columns were not considered by the conflict resolution, e.g. winner / looser. This issue is fixed.
  • Long log messages were truncated in GUI. This issue is fixed.

Fixes:

  • Initial synchronization with mapped key issue. Cannot find column 'xxx' issue fixed. 
  • Backward compatibility of metabase files after version upgrade implemented.

Changes:

  • A new parameter ‘Overwrite destination’ is added on connection level for unidirectional connections. If true it allows deletes and updates in the destination list of an unidirectional connection on initial synchronization. Default is false.
  • Both reading and writing complex types are supported in OData provider now. This can be used e.g. with Microsoft CRM Online connections. See sample files and FAQs for more details how to manage.
  • All sample connections start with the connection title and file name "Sample..." now.
  • Small interface improvements in Connection Manager

Fixes:

  • Initial synchronization issues in some certain cases are fixed.

Version 3.1

 

 

New features:

  • Document library synchronization feature added. See new sample connection file for more details.
    Please note:

    - The primary key needs to be set for both data entities to the column name “FilePath”.
    - There must be two field mappings for the columns FilePath and FileContent.
    - This is an issue of version 3.1 and will be automatically set in future versions.
  • Microsoft Dynamics CRM support using Odata feature added. See new sample connection file for more details.
  • Sample connection files added to the setup for document library synchronization, and CRM Odata
  • Encryption option for select statement, connection string, primary key, replication key added.
  • Save configuration command added to the Global setting screen(log level and service start mode
  • A new optional 'Scope' parameter added to the Layer2.SharePoint.Provider connection string. 

    For scope value 'Recursive': it reads recursively all items in a SharePoint list with folders. 
    Please note that no folders returned. All items are placed in a flat list.
    For scope value 'RecursiveAll': it reads  recursively all items in a SharePoint list including folders.
    Please note that folders are returned as items. All items are placed in a flat list.
  • Form-based Authentication (FBA) now supported for SharePoint servers using Cookie Manager. Please use in connection string: Authentication=IECookie.
  • Further usability and performance improvements

Bug fixes:

  • Black window issue using the connection wizard with windows 7 theme activated is fixed.
  • 32 bit compatibility improved.
  • SharePoint client libraries merging issue (on GUI side) fixed.
  • On merged version Cookie Manager does not show cookie's URL and expire date bug fixed.
  • High memory consumption during synchronization on 'Trace' log level issue fixed.
  • Mapped primary key issue fixed

Next Steps planned:

  • Document library and file system replication.
  • Dedicated providers for Microsoft Exchange and other web services
  • If you have any detailed requirements, please send to sales@layer2.de. 
    We will help you as soon as possible to meet your requirements.

Known issues:

  • Calendar type of list is not supported because of CSOM issue with End Date. As a workaround custom lists can be used with calendar view to sync date / time-based information.
  • There is a SharePoint limit for lookup fields using the default view allitems.aspx. As a workaround create your own view and connect, that works great.
  • Attachments are not synced with lists.
  • Folders are not fully supported with SharePoint lists. See above for scope option to workaround.
  • Managed Metadata is not supported at this time.
  • SharePoint metadata like created, last modified, user information is modified during sync.
  • SharePoint lookups are not "translated" between different systems.
  • SharePoint user or group fields are not "translated" between different systems.

 

Version 3.0

  • Connection Manager comes with GUI now as Microsoft Management Console snapp-in. You can continue to edit the XML-based connection files, if required. We advise to use the new UI.
  • Support for Open Data protocol, e.g. to more flexible access SAP, Dynamics CRM etc.

 

Version 2.3 - 2011-10-10

 

  • Primary keys can be case sensitive now.
  • In some configurations bi-directional connection was forced instead of unidirectional. This is fixed in the current release.
  • SQL Azure is fully supported now.

 

Version 2.0 - 2011-09-06

 

  • Bi-directional replication is supported now (if supported by data source). Please simply remove the data entity type (source/destination) or set to "bidirectional" to activate this feature.
    Please note: Bi-directional is the default connection type starting with this release.
  • See manual for conflict resolution options, e.g. on field level.
  • Mapping of primary keys is no longer needed. But both data entities must continue to have primary keys.

 

Version 1.2 - 2011-08-15​

 

  • An issue with workflow fields in destination list was fixed.
  • There is an unfixed issue with lists using lots of fields, especially a large number of calculated fields. It may cause "Server Error 400" in some cases. Please adjust batch size in this case down to some items only, to give SharePoint time to recover. By default is: BatchWriteItems=5000

 

Version 1.1 - 2011-07-15

 

  • Authentication issues with alias domains are fixed with this version. You could not authenticate with V1.0, if using alias domains (not ???.sharepoint.com). Now you can add an additional Realm option to connection string in this case that contains the original domain for authentication:
    Realm=https://myOriginalDomain.sharepoint.com
    That fixes the authentication issue.

 

Version 1.0 - First production release

 

  • A Windows Service is provided to operate your background updates automatically without any restrictions. Please note: When changes are made to the configuration files, the service has to be restarted. Alternatively you can force the connection service to run as application in foreground for better testing.
  • Office 365 Cookie Manager is installed with "Complete Installation" option only. It os not required to establish a connection to Office 365. Please use Authentication="Office365" with user name and password instead of cookie based login. 
  • All field mapping is done by field names via XML. The SharePoint INTERNAL column names are used for mapping (not column titles). See log mapping check in log files for more information. In case of database connections, please use aliases in the SQL query or view (e.g. select myField as myAlias from myTable) to use the auto-mapping feature - or map columns manually.
  • A "primary key" is required on both sides, data source and destination, e.g. a customer ID or SharePoint item ID. It can be a combination of multiple fields / columns (e.g. contact full name and company). In most cases (including SharePoint) it will be detected automatically.
  • Primary keys must be mapped. Example: A primary key "ID" in a SharePoint data source list can be mapped to a column "SourceID" (integer) in the SharePoint destination list in the connection settings file.

  • You have to use the so called invariant name to declare a provider in the configuration file as data entity property (see your machine.config for installed providers). Typically the follwing providers are used:
    Layer2.SharePoint.Provider ... comes with the Cloud Connector to connect to SharePoint 2010 via CSOM (Client Side Object Model)
    System.Data.Odbc ... the .NET Framework Data Provider for Odbc used to connect via ODBC
    System.Data.OleDb ... the .NET Famework Data Provider for OleDb used to conenct via OLEDB
    System.Data.OracleClient ... the .NET Framework Data Provider for Oracle used to connect to Oracle database
    System.Data.SqlClient ... the .NET Famework Data Provider for SqlServer used to connect to Microsoft SQL Server

  • Calendar lists are not supported yet because of an currently unsolved Microsoft CSOM issue.

  • User / Group columns that cannot be resolved at the destination system can cause circular updates. Please exclude those fields from auto-mapping.
  • Be careful using lookups in data destination. Item IDs in source list and destination list can be different. SharePoint has no API to create new items with a defined item ID.
  • There is an unsolved authentication issue with URLs that use an alias instead of the original namespace. That is fixed in V1.1.
