    [ http://jira.jboss.com/jira/browse/JBSEAM-2524?page=comments#action_12399982 ] 

Alessandro Lazarotti commented on JBSEAM-2524:
----------------------------------------------

The class org.jboss.seam.core.Manager have the method:  

"private boolean restoreAndLockConversation(ConversationEntry ce)"

... with the conditional:

      if ( ce!=null && ce.lock() )

Ocurrs the bug when "ce.lock()" return false (for some reason),  so is called   "initializeTemporaryConversation()" and the conversation is discarded.

It runs three times on this conditional in the same request. In the first time return true, second return true and of third return "false" and generated the error.

This is strange because happens even without access concurrent. In Firefox isn't common happen, but in InternetExplorer every time. 
What happens with only:  "if( ce!=null )", without ce.lock?:
