-------------------------------------
Hello Pete,
I have currently version 2.0.2.CR1 and my Manager.class
has
public void leaveConversation()
{
initializeTemporaryConversation();
}
So is that fix for 2.0.2.CR2? of for 2.0.2.CR1 that is available in SVN?

> 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();
