Hello, the Ecore model I am working on has a bunch of classes which have various derived references to other models elements. These derived references are backed up with OCL constraints. The notifier of these derived references have been generated by the EMF-IncQuery, so the UnsupportedOperationException is not an issue anymore. But the thing is, I couldn't manage to validate the instances of my model, since derived features can't be set via Properties view (after loading an instance of the other model to be referenced). Is there a way to achieve that practically? Thanks a lot!

Hi

Sorry too vague and complicated to answer directly: see
