Java Development Tools

Hi,

I have the following refactoring problems in JDeveloper 10.1.3.2:

1) When refactoring Associations, Entity/View Objects, Java classes ... and running my application again, I get some errors. These errors are for the reason that all the references to the refactored file/object have not been updated properly and the application can't find the refactored file/object.

2) Some files can not be refactored although the Refactor menu item exists for them.

3) When moving a file using refactor, the file gets deleted from its original location and created at the new location. This makes the versioning history of that file to be deleted in CVS. I think the file should be branched to preserve its history.

Are these bugs or there are solutions for them?

Thanks,
Saeed

P.S.: The problem in item one does not exist in my colleagues machine although everything is the same in our machines.
