Just do it. :-P

That seems good.

It sounds like perhaps the save is causing your resource's objects to be
turned into proxies. That shouldn't be the case except if some other
editor change the underlying resource external to the editor.

I guess so, but in the generated EMF editor, that shouldn't happen. The
resource delta processing knows which resources were saved and ignores
those expected deltas.

You could listen for changes to the contents of the resource and call
setInput again with the new contents. But it sounds to me like you have
some bogus resource delta processing happening...
