I am still fighting with multi page editors.
Now I have editor inherited from CompilationUnitEditor that creates
CTabFolder, places one one tab CompilationUnitEditor, and on second
tab - GEF editor. In Java editor all actions work, but not in GEF
editor - DEL key does nothing (it works, if I use this GEF editor
alone, without multi page). And when I select "Delete" from menu,
it is handled in Java editor, even when GEF editor is active.
Yes, I understand, that I should switch active editor for this
action to GEF editor. But how? I don't know. :-(
Yes, I can access delete action using
getActionRegistry().getAction(GEFActionConstants.DELETE)
but what should I do after this?
Can anybody help?

Yes, I've tried this way.
But when I place CompilationUnitEditor as page, indent stops working,
some navigate actions (like F3) does not work, because they check, that
current editor is JavaEditor.

Yes, I know, when user switches page.
But what should I do in this case?
I've tried many ways, but all of them are unsuccessfull. :-(
Currently I use following code:
IActionBars bars = getEditorSite().getActionBars();
String id = IWorkbenchActionConstants.DELETE;
IAction action = getActionRegistry().getAction(GEFActionConstants.DELETE);
System.out.println("action: " + action);
bars.setGlobalActionHandler(id, action);
bars.updateActionBars();
I see, that global action disabled, GEF's DeleteAction is disabled, and it does
not receive notification when I select EditPart in GEF editor. I think, this is
bacause selection provider is CompilationUnitEditor, but I don't know how to
make GEF editor selection provider. :-(
I've tried (unsuccessfully) this code (from hookGraphicalViewer):
getSelectionSynchronizer().addViewer(getGraphicalViewer());
getSite().setSelectionProvider(getGraphicalViewer());
Still no notification. :-(

keybinding, which is implemented using accelerators on the shell. So, when
the graphical page is displayed, ALL keys from the Java editor will be
mysteriously stolen. Maybe the DEL key is actually deleting text on the
other page.
You need to switch keybinding contexts whenever you switch pages in your
editor. Let me know if this guess helped any.

Thanks, I've solved my problem.
I just bind GEF actions to global actions and set selection
for GEF ections directly in graphical viewer handler.
