(In reply to comment #0) > VC registers PostSelectionListeners to both VA and VB. How do you do this? I call the following method of ISelectionService public void addPostSelectionListener(String partId,ISelectionListener listener); This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie. |
Build Identifier: M20110210-1200 PagePartSelectionTracker searches for the part in the current perspective if created. If that part is not contained in the current perspective it will not get a reference right away but obtain it if the part is created later on. The problem is when the wanted part is not in the current perspective but has been created already. I guess this is a rather unusual use case but this gave me quite a headache because its not that easy to reproduce if you dont know exactly what the problem is. There is a quite simple solution for this since PagePartSelectionTracker already implements IPartListener one can simply change the currently empty partActivation method to call partOpened if the Tracker does not have a part-reference yet: public void partActivated(IWorkbenchPart part) { if(getPart() == null) { partOpened(part); } } Reproducible: Always Steps to Reproduce: Lets say we have three views (VA,VB,VC) and 3 perspectives (PA,PB,PC) containing them like this: PA contains VA PB contains VA and VC PC contains VB and VC VC registers PostSelectionListeners to both VA and VB. The following steps produce the problem: 1.) launch App (automatically opens PA) 2.) switch to PC, this creates VC and since VC registers PostSelectionListeners it also creates two PagePartSelectionTrackers for VA and VB but since PC does not contain VA the Tracker does not have a part-reference. The Tracker would obtain this reference later on if VA was created but since its already there it will never get one 3.) switch to PB and watch nothing happen in VC when you change the selection in VA
