Strange ConcurrentModificationException in 2.2.0
Hi,
I'm using seam 2.2.0GA with Icefaces 1.8.2
I have some abstract components with CONVERSATION scope, implementation classes which extends my base classes works fine, but for one component I have strange exception on rendering this view. I was looking for similar problems and I have found a lot of similar exceptions in JIRA but unfortunately I don't think that this is my case. I have seen similar exception on autologin(I don't use autologin). I have disabled debug mode, and my server is not under heavy load. So I really don't have any clue why this happening.
What is special in my application is that I'm using (Manager.instance().switchConversation(id), Conversation.instance().beginNested();) because @Begin annotation is not inherited.
My exception is thrown before my view is rendered:
