http://download.eclipse.org/e4/sdk/drops/I20100616-2127/index.php. After starting a new workbench I see toolbar icons which are all active all the time but do nothing. The 'Pin Editor' toolbar button seems to do nothing even if editors are open.
If I open on a clean workspace, there's a handler created for AUTOGEN:::org.eclipse.jdt.debug.ui.BreakpointViewActions/org.eclipse.jdt.debug.ui.actions.AddException The RAT for that activation runs against (what seems to be) the window context while I switch views in the java perspective. If I simply open the breakpoints view, the exception breakpoint dialog opens. If I then open the Debug perspective, it appears to work. If I open the Debug perspective without opening the view (it goes through the perspective switcher code, not the WorkbenchPage code), the HandlerActivation is never run again. But I'm not sure why, since the handler was never removed as participating (so it should still be a runAndTrack against the WorkbenchWindow context and it doesn't look like legacyActionPersistence was removed).

Oleg, my RAT is against the window context, but opening the perspective dialog and closing it causes 1) the window context computation (which worked as normal), and then 2) the dialog context disposal causes the removeAll(eventsContext) in TrackableComputationExt#update(ContextChangeEvent event) Since it was entered against the window context, I wouldn't expect a child context dispose to take it out.

Created attachment 173076 [details] Tests to reproduce the context disposal problem I'm not 100% sure if this is the same thing but the test certainly fails in a way I would not have expected it to fail.
Created attachment 173112 [details] Patch for RAT disposal The patch fixes the problem demonstrated by Remy's tests. The RunAndTrack instances did not have any idea what is the contexts that they are originally created on, and, hence, treated disposal of any context they touched as a end-of-life event. I changed code to store the originating context for RunAndTrack instance. This fixes Remy's JUnits but the toolbar button still does not work. (Patch for RAT disposal applied to CVS Head.)
After some more debugging of the original problem, it seems that there is no handler for the toolbar item after swtich perspectives: - Set up a workspace: (default) Java perspective is open; open a Debug perspective; make "Breakpoint" an active view. Restart. - After restart click on the "add Java exception breakpoint" tool item. The dialog starts up. Cancel the dialog. - Switch to Java perspective; switch back to Debug perspective using perspective switcher. - Click on the "add Java exception breakpoint" tool item. Nothing happens To see why: place a breakpoint in HandlerServiceImpl.executeHandler(). Notice that lookUpHandler(context, commandId) returns null after perspective switch. (It returns the proper handler before the perspective switch.)
The immediate problem is that ISources.ACTIVE_PART_ID_NAME needed to properly evaluate enablement is set in TWO places, and only one of them tracks correctly perspective change. - First place: E4Application's runAndTrack based on IServiceConstants.ACTIVE_PART This sets the value on the Workbench context and is properly updated - Second place: WorkbenchPage.updateActivePartSources() This sets the value on the IDEWindow context (child of the Workbench context) is breaks after the first perspective change So, after two perspective changes we have: Workbench context -> proper value for ACTIVE_PART_ID_NAME | child | IDEWindow context -> stale value The IDEWindow context is used for evalueations and its stale value overrides correct value in the parent. In the next installement: the WorkbenchPage.updateActivePartSources() seems to break because of the PartService....
This is caused by the same underlying problem as the bug 318460 (PartService stops getting updates). *** This bug has been marked as a duplicate of bug 318460 ***
