Hi Hamzah!

I'm registered at [email protected], just didn't have time to response. 

In a new TomEE we should use a new MyFaces. In the newer MyFaces, the 
DebugPhaseListener is not enabled by default (as it created a few side 
effects). So this issue should not happen. In fact we did not do a single 
commit for OWB-626 ;)
I'm also not sure if this is an OWB related issue as we are still using the 
same 1.1.4 version of OWB since a few months afaik.
I also looked at the changes in the WebBeansPhaseListener. Almost all of of it 
is from 2009 and 2010, no change since march 2011...


The BusyConversationException really only happens when a Conversation with the 
same Id is touched from 2 different threads.

In general, I consider the CDI Conversations pretty much broken. This effect 
could e.g. also happen if you have AJAX enabled, or if you did a redirect. I 
recommend to use CODI Conversations instead.

Here is what I mean with the redirect problem:

Consider you have a request A and at the time r there is a redirect which leads 
to request B. The underlines visualize some other work:

A: request______redirect________________response
B:                                   request________________________response

As you see above, the request A needs quite some time for cleaning up after the 
redirect. E.g. serializing the ViewMap, backing up the session for cluster 
replication, etc. And in this time (if the client is fast enough) you will 
already be hit by request B. 


This really su....s conceptionally. You will btw have the same problem with JPA 
if you store the EntityManager longer than a single request.

LieGrue,
strub
