Image cross model association

Hi all,  Does anyone know of any issues with using across model association for images.  There are two entities (A + B) that link to the same image generalised entity (C). A is on the same domain modal as C but B is on separate modal.  When adding an image (C) to the B object I get an error: I have set up an test with everything the same apart from the image entity being on the same domain modal instead of a different one and this work without issues.  Does anyone have any thoughts?

I never saw this happen.

When you add the same image to object A the issue does not occur?

I would expect entity access/module roles to be the difference between A and B.

But it also sounds like a Mendix bug, it may be worth filing a support ticket.
