[Transaction] Redo(Undo)ActionWrapper memory leak? [message #84393] Tue, 22 May 2007 07:16 Go to next message

Hello,

I use EMF workspace integration plugins in my App. (currently 1.1M7). Today
I discover strange behavior with my profiler. When I close any of my editors
I left in memory my TransactionalEditingDomainImpl. I create one ED for each
editor and dispose it after close. But my ED is held in memory by two
references from undo/redo action wrappers. I don't know how to release these
references.

Maybe someone can help me with this or maybe this is a small bug?

Stack from profiler looks like:
org.eclipse.emf.transaction.impl.TransactionalEditingDomainI mpl
domain of org.eclipse.emf.workspace.ui.actions.RedoActionWrapper
this$0 of org.eclipse.emf.workspace.ui.actions.RedoActionWrapper$1
ownerAccess of org.eclipse.emf.workspace.ui.actions.ActionWrapperHelper
this$0 of org.eclipse.emf.workspace.ui.actions.ActionWrapperHelper$2
[11] of java.lang.Object[12]
listeners of org.eclipse.core.runtime.ListenerList
listenerList of org.eclipse.ui.internal.PartListenerList
listeners of org.eclipse.ui.internal.PartService
partService of org.eclipse.ui.internal.WorkbenchPagePartList
partList of org.eclipse.ui.internal.WorkbenchPage
lastActivePage of
org.eclipse.ui.internal.ide.application.IDEWorkbenchWindowAd visor
windowAdvisor of org.eclipse.ui.internal.WorkbenchWindow
activeWorkbenchWindow of org.eclipse.ui.internal.Workbench [Stack

Sorry,

I don't found setEditiongDomain() method on these actions. Now I call
setEditiongDomain(null) from dispose of my ActionBarContributor and ED is
gone. ;D
One strange thing in this is that EditingDomainActionBarContributor not
destroy this references in own default dispose.

Grzegorz,

The generated editors do this in their dispose, which should cause the
EditingDomainActionBarContributor to call deactivate().

if (getActionBarContributor().getActiveEditor() == this)
{
getActionBarContributor().setActiveEditor(null);
}

I'm not sure I understand exactly what you think the dispose method
should do for the EditingDomainActionBarContributor, but if you explain,
what you think is needed and why, it might be something we could add.

Also, please use the EMF newsgroup for asking about transaction now that
this component has graduated from EMFT and moved to EMF. (I've added it
to the "to" list.)
