No doubt, I don't have the stack trace at hand, but I can point you to line 1066 in cleanupFeedbackMessages() in Session. The issue here is that the Iterator returned from the a CopyOnWriteArrayList throws this exception from a call to remove, set, or add. Here's the quote from CopyOnWriteArrayList:

These methods throw * <tt>UnsupportedOperationException</tt>" Problem was manifesting itself the first time a message was added to feedbackMessage igor.vaynberg wrote: > > your fix wont do, the list needs to be threadsafe > > can you please paste the stacktrace so we can see where the remove() is > being called from? > > -igor > > > On 1/22/07, TimOBrien <[EMAIL PROTECTED]> wrote: >> >> >> I updated my copy of trunk, and I kept on getting this message: >> >> java.lang.UnsupportedOperationException >> >> java.util.concurrent.CopyOnWriteArrayList$COWIterator.remove( >> CopyOnWriteArrayList.java:937) >> wicket.Session.cleanupFeedbackMessages(Session.java:1067) >> >> Tracked it down to CopyOnWriteArrayList in Session for feedbackMessages. >> Changing the type of feedbackMessage to ArrayList, and rebuilding seemed >> to >> fix the issue.
