I write a editor using a MultiPageEditorPart with different pages, which
are containing editors subclassing the GraphicalEditorWithPalette. I
register some global Actions in the MultiPageEditorContributor like this:

public void setActivePage(IEditorPart part) {
if (activeEditorPart == part)
return;

activeEditorPart = part;
IActionBars bars = this.getActionBars();
if (bars != null && part instanceof MyGraphicalEditorWithPalette) {
bars.setGlobalActionHandler(ActionFactory.UNDO.getId(),
((MyGraphicalEditorWithPalette) part)
.getAction(ActionFactory.UNDO.getId()));
bars.setGlobalActionHandler(ActionFactory.REDO.getId(),
((MyGraphicalEditorWithPalette) part)
.getAction(ActionFactory.REDO.getId()));
bars.setGlobalActionHandler(ActionFactory.DELETE.getId(),
((MyGraphicalEditorWithPalette) part)
.getAction(ActionFactory.DELETE.getId()));
bars.updateActionBars();
}
}

MyGraphicalEditorWithPalette contains a method getAction() which returns
"getActionRegistry().getAction(key)"

It works fine with UNDO and REDO. But I can't select and execute a
DELETE-Action e.g. for a children EditPart of the contents EditPart.

Thanks

Maybe the problem is to find the right EditPolicy? I've studied the flow
example and I think the EditPoliy responsible for enabling a Delete
Action must subclass the ComponentEditPolicy? I've done all this but it
don't works?

Thanks for the hint. I made it that way and it works fine with EVRYTHING
like UNDO, REDO, PRINT... but doesn't with DELETE?

I found that the List returning by "getSelectionActions()" contains
"delete" (so in principle DELETE must be possible) but the DELETE-Action
isn't enabled...

I think there must be some trouble with my EditPolicies...
