COuld you send me your example model? I haven't actually played with different background colors much.
I'll send you the workspace. It was a very simple project with two classes (as shown in the screenshot).
OK, this is for a case that I'm afraid to say I hadn't even considered -- namely contained packages in the diagram itself. Often these are flat in the model. The good news looks like it might explain a number of things that are going wrong.
OK, I've looked into this a bit.. There seem to be some pretty funky issues with packages within ecore diagrams. I've never used them this way, and I don't think most people do.. Instead we tend to have different ecorediag files for each package. See for example: bug 149547 bug 165866. I tried one simple way of dealing with this and it was semi-successful, but it ended up breaking some other stuff. There will be a fair amount of fixes involved for functionality that isn't used that much. The other issue is that packages are drawn with gradient background, which our technique doesn't work perfectly with. This issue will come up with other compartment type models, probably, but it is a pretty significant set of tasks. So.. I know this is weak, but I'm inclined to consider not supporting focusing for internal compartments (i.e. packages) at this point and revisit later. Thoughts?
Sounds reasonable to me. Please feel free to mark this as an enhancement and move it to the appropriate place. Please list this limitation somewhere on the Wiki page.
I'm making this represent just graceful non-support for package level so that we don't get any exceptions like the one above.
Should be working. Packages as a whole are faded, but interior classes for those packages are not.
