[jboss-user] [JBoss Seam] - Manager.switchConversation via Ajax4JSF actionListener doesn

Hi all, I'm using Seam 1.2.1 GA on JBoss 4.0.5. I have a conversation list dropdown in my facelet view, like this: <h:selectOneMenu id="conversations" class="navlist" | value="#{switcher.conversationIdOrOutcome}" > | <f:selectItems value="#{switcher.selectItems}"/> | <a:support event="onchange" | onsubmit="showLoading('NavForm:conversations')" | oncomplete="hideLoading();" | actionListener="#{switcher.select}" | reRender="navlists" /> | </h:selectOneMenu> Switching conversations with a:support doesn't work in a stable manner. In particular, the ce.lock() call in the following code snippet (from org.jboss.seam.core.Manager) returns false (tryLock times out) under circumstances I don't really understand: public boolean switchConversation(String id) | { | ConversationEntry ce = ConversationEntries.instance().getConversationEntry(id); | if (ce!=null) | { | if ( ce.lock() ) | { | unlockConversation(); | setCurrentConversationId(id); | setCurrentConversationIdStack( ce.getConversationIdStack() ); | setLongRunningConversation(true); | return true; | } | else | { | return false; // <-- times out (sometimes, not always), conversation not switched | } | } | else | { | return false; | } | } What does the call to ce.lock() really mean? And can anybody explain why this would fail? Is there a problem with calling switcher.select() from an a:support? And is that in any way related to http://jira.jboss.org/jira/browse/JBSEAM-1832? thanks, Karl View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4120106#...
