[Mukesh Patel]

I am getting exceptions catpured below when I try to reverse engineering UML and also a pop-up window with the following message:

creation of element failed

see error log for more details

I am also not able to drag individual classes into the uml project.

Any thoughts on what may be wrong.

Thanks

[Riyad Kalla]

Is it every file you try and reverse engineer or just some? Can you post an example file that causes the problem?

[hprange]

I’ve seen something related with this problem here, but not found a solution. I catch this exception when I’m trying to reverse engineering a class created by Visual Editor.

[dmacdaddy]

Any updates on this? I am having the same problem and would like to know if it was an issue with MyEclipse or an error on my part…

[Riyad Kalla]

dmacdaddy,
Can you give us a bit more information? What kind of code are you trying to rev-eng? Are you using drag and drop or the wizard? Are you getting an exception in your log file? What are your install details (MyEclipse > Installation Summary > Installation Details)?

[Tim Brown]

I am having the same problem. It bombs with that error on the first class it comes accross that uses generics.
Does this version of the UML support Java 5?
