CLONE -Locking issue for ConversationEntry when using Conversation.instance().leave()
-------------------------------------------------------------------------------------

                 Key: JBSEAM-2926
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-2926
             Project: Seam
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.0.1.GA
            Reporter: Tomas Cerny
         Assigned To: Pete Muir
            Priority: Minor
             Fix For: 2.1.0.BETA1, 2.0.2.CR1


When using Conversation.instance().leave(), it seems that the ConversationEntry lock is not released.  *Sometimes* it can be obtained when attempting to resume the conversation but other times it cannot.  This results in the user being redirected to the no-conversation-view-id after the concurrent-request-timeout expires.

This can be observed by placing Conversation.instance.leave() in an action that redirects to another page.  Then simply use the back-button and resume the conversation by clicking a link on the page.  You may have to try this several times to get the result.  I will see if I can create a reliable test case and attach it.

Manager.switchConversation() performs an unlock of the ConversationEntry prior to switching, which would also make sense in the case of leave (since it is really a switch to a temp conversation).

The workaround is simply executing the following:

Code:

Conversation conversation = Conversation.instance();
        
ConversationEntry entry = 
            ConversationEntries.instance().getConversationEntry(conversation.getId());

conversation.leave();
entry.unlock();
