Hi,

I draged and droped a class onto a class diagram and that worked fine 🙂 but then I wanted to to do the same onto a sequance diagram and then I got a ClassCastException.

You can find the exception and my installation summary below.

jrpe,
Sorry to hear you are running into this issue.
I could not replicate the issue at my end. Can you please send me a sample project (with 2 or 3 uml files and java class files) to test and also the steps to reproduce the issue. You can PM the project or send an e-mail to support@genuitec.com. Please add a note “ATTN: Joy” in the subject line. Also refer the post link in the e-mail.
