Below is install details (MyEclipse > Installation Summary > Installation Details)

When I try reverse engineering code in a project I get a dialog with the following:

creation of element failed

see error log for more details

This happens even if I try with only a single simple class checked. Drag and drop seems to work as I tried it with several packages in the project successfully.

The log contains the following exception after every attempt with the wizard:

Can you try switching to a new workspace, create a new project and try reverse engineering a simple class using the wizard? Do you still get the error dialog ?

[greenbird]

I created a new workspace and project and copied the source from one of the projects I tried to reverse engineer above and it worked. The workspace above is rather large and involves a number projects all with custom ant builds in addition to the normal Eclipse build. It would be time consuming and difficult to recreate so I really need to fix the original workspace. Can you give me any hints on where I can look to find the problem with the original workspace?

[haotten]

This exact same issue is occurring for me as well….

[Loyal Water]

Have you guys tried starting MyEclipse using the -clean command ?

[haotten]

the -clean command did not help… still getting the following error :

[Riyad Kalla]

haotten,
Just to clarify, Drag and Drop works fine for you, but rev-eng wizard dies with the error above?

For both of you, does the code use Java 5 constructs or straight Java 1.4?

[greenbird]

Mine uses lots of Java 5

[greenbird]

Also -clean didn’t change anything.

[Riyad Kalla]

Guys if any of you can create a small Java project with the source code that cannot be reversed and a small example diagram with instructions on how to reproduce the issue, then email it to me at support@genuitec.com ATTN Riyad, with a link to this thread, I can test it and file a bug report immediately and see if we can get this fixed.
