Hiding nodes in the model tree of EMF Compare

I would like to hide some tree nodes in the match results of EMF Compare, since they are just containers with no meaning to our users.

I have tried two approaches, but both result in some unwanted side-effects.

1. Using a more narrow scope

   This results in the separate diffs being available, but without the enclosing tree structure of the model.
2. Using a post processor to remove some container objects from the tree of matches.

   This is more of a success in that the resulting tree structure is exactly what I'm after. This however breaks navigation in the bottom pane.

I'd be really happy if someone could have a look and see what my attempts are missing.

Thanks,

Mattias

I got a reply in the Eclipse forum. An EMF Compare core dev let me know that this is not possible without breaking behaviour as I described.

So for the rest of you trying: no dice.
