Although, I am not able to reproduce it by double clicking, (still trying), I think this might not be a portal issue. I will keep this under samigo unless I find it is related to portal.

Thanks.
Karen

This isnt really a portal issue (although the stack trace appears to come from there)

If there is a problem with the portal on this please add the portal tag back in and assign to me (or tell me)

Thanks
Ian

We are getting quite a lot of these in 2-3-x during assessment delivery - seems to be about 10% of users, e.g.

Dealing with unintentional double-clicks is a known and common problem in JSF, all right. But the problem report doesn't mention that it was the cause of this particular stack trace. Daisy, were you able to reproduce the exception by double-clicking?

Here's a not-bad discussion thread on the subject:

http://forum.java.sun.com/thread.jspa?threadID=665472

Since that about uses up my wisdom on the subject, I'm passing this back to Daisy....
