I cannot save the form if the form is using a class level variable that is defined using java generics (i.e. Map<Integer, String> a = new HashMap<Integer, String>(); ) The variable does not need to be used in any methods, just having it there causes a problem.

I created this sample project to try and reproduce this issue and couldn’t… could you try downloading that and importing it and working with it and seeing if it gives you the same issue? I created a new form and copy-pasted your question generics line at the top then closed and reopened and worked with the form some more and everything seemed fine.

[Mike Groys]

Nope, same issue. However, I think I have figured it out. My workspace default compiler compliance setting was set to 1.4, since I have a bunch of projects that use 1.4. The project I am working in, is overriding the workspace default to “5.0” For whatever reason, it seems that Matisse GUI editor is ignoring the override and uses the workspace default. After I changed the defaults, the generics are no longer an issue.

Ahh!

Greg you nailed it, that’s the combination that causes the problem to surface. I’ll file it right away as a bug. Thanks.
