Team for Capella 1.1.4 (2018-06-11)
Compatibility: Capella 1.1.4
What's new
The Team for Capella 1.1.4 maintenance release brings three major changes compared to Team for Capella 1.1.3:
- Save protection by a lock on the shared resource : allows to display a "Save canceled, retry later" popup to other users who try to save while a save is already in progress. This allows to avoid several kind of Save Failed errors or CommitConflict exceptions. It can be disabled with the system property -Dfr.obeo.dsl.viewpoint.collab.disableSaveProtectionByRemoteAirdLocking=true
- Durable locks are now disabled by default, ie. locks are released when a user closes its connected Capella project. The durable locks feature can be enabled using the plugin_customization.ini mechanism: in capella/eclipse/plugin_customization.ini just add fr.obeo.dsl.viewpoint.collab/PREF_ENABLE_DURABLE_LOCKING=true
- XmiIds synchronization can be disabled with the system property -Dcom.thalesgroup.mde.cdo.emf.transaction.disableXmiidsSynchronization=true This allows several performance and stability improvements on models with many (and/or) big representations but this also disables the diff-merge capabilities for local vs distant models and the identification of representation data between each import (Importer, import wizard).
Important note
For this specific version it is recommended to use a new workspace: durable locks have been disabled by default but older versions used to activate this feature as a user choice. It is also possible to clean the old workspace by removing the PREF_ENABLE_DURABLE_LOCKING=true preference value from the workspace metadata located in: YourWorkspace\.workspace\.metadata\.plugins\org.eclipse.core.runtime\.settings\fr.obeo.dsl.viewpoint.collab.prefs.
Fixed Issues
This version also introduces several fixes:
- Fix message about LockedInstanceException; When several objects must be locked, a global LockedInstanceException is thrown for all objects even if only one is locked. Only the first object of the list used to be displayed as locked even if it was not. Now the message is clearer and explains that at least one element is locked.
