I need to be able to get a reference to my GraphicalEditor from an EditPart.
Is there a way to do this?
I wrote a custom view which is a ISelectionListener listening for EditPart
selections. It makes updates to my model without using the command stack.
I need to be able to setDirty() on my GraphicalEditor.

Well My view knows nothing about the command stack or the GraphicalEditor,
it only knows about selected objects that implement my interface. I will
look into hooking it into using the command stack, but right now I'm really
not sure how to do this as loading the view does not seem to pass through
the GraphicalEditor.getAdapter() method. If it did, I would be able to
grab the reference to the GraphicalEditor.

You can register your view as a part listener to the current workbench
page. Then you get notified whenever an editor get (de)activated (or
more generally, whenever a part (=editor/view) gets (de)activated). Use
this to track the active editor. Whenever the active editor changes, ask
the new active editor for a command stack:
editor.getAdapter(CommandStack.class)
Then it doesn't really matter anymore whether the editor is an instance
of your GraphicalEditor so you won't even have to cast to
(YourGraphicalEditor). Make sure your GraphicalEditor returns its
command stack in its getAdapter() method. It might already do this (I'm
not sure); else you'll have to override.

Martijn.
