I have two mixed java/scala projects A and B where B depend on A.

If I do a refactor-rename (package) in either a .java or a .scala class in A, scala-ide does not make the necessary changes in B and I get compilation errors.

I have not tested for pure scala projects but I suspect the problem applies here too.

I should think this problem is quite serious as being able to safely rename stuff is critical for any refactorings and hence for maintaining scala based software.
