Thanks for your help, Paul.
I've tried this, and put System.out.printlns in the:
EditorInput#saveState
EditorInputFactory#createElement
Editor#saveState
Editor#restoreState
methods.
For the purposes of the example, my IEditorInput contains a String and
my Editor contains a Text widget. The "text" property of the Editor's
Text widget is data-bound to a property of the EditorInput. The editor
itself has no state that it persists--all of its state is persisted in
the IMemento in the IEditorInput.
Running the example, creating two editors, and typing "Editor 1" into
one and "Editor 2" into the second yields the following output when
shutting down and restarting the application:
Shutdown:>>>>>>>>>>>>>>>>>>>
EditorInput.saveState>>>> Editor 1
EditorInput.saveState>>>> Editor 2
EditorInput.saveState>>>> Editor 2
EditorInput.saveState>>>> Editor 1
EditorInput.saveState>>>> Editor 1
EditorInput.saveState>>>> Editor 2
Startup:>>>>>>>>>>>>>>>>>>>>
CreateElement>>>> Editor 1
and no editors are actually restored.
Notice also that Editor.saveState is never called.
I feel like there must be a "Doh!" somewhere, but am clueless as to
where...
Source code to my example is available at:

Thanks in advance,
Dave Orme
