Hi

I seem to have the same problem as is described in the following post:

http://www.myeclipseide.com/PNphpBB2-viewtopic-t-23263.html

I don't understand the solution described here however. How to I get to the "Types with Problems" Dialog?

Either way, this seems to be a bug.... see NullPointerException which is in the log below.

Thanks in anticipation

OK, thanks. But if you don't get a reply could you simply review the problem report I've raised and advise? I really need this feature to work.

Thanks

I just looked at http://www.myeclipseide.com/PNphpBB2-viewtopic-t-23263.html which seems to be exactly the problem I am having and it explains the "Types with Problems dialog". I don't get this... I just get no response from the UI when I click the button and the resultant NullPointerException is logged.

mdwrim,
Can you send me a UMR to reproduce this issue at my end. You can hit the pm button at the bottom of my post and send me the UMR.

Has this been resolved? I am getting similar problems with 7.5, specifically if I delete or change the name of a class for which some Java code has previously been created. It seems like some link is being retained even though the class is deleted or changed on the model. I am using the delete function on the drop down menu. I am still using UML1 since UML2 has even more problems.

jhebley,
We had faced a similar issue in 7.1 that was fixed for the 7.5 release. Could you please list the exact steps to help us reproduce this issue at our end.

Could you also go to MyEclipse > Installation Summary > Installation Details and paste the information here for us.
