  1. POending conversation scoped bean and then redirect when command button clicked
    text
    copied!<p>I have a simple command button</p> <pre><code>&lt;h:commandButton value="Create Form Event" action="#{formEventController.createFormEvent}"/&gt; </code></pre> <p>which calls the following simple action listener</p> <pre><code>@Named @ConversationScoped public class FormEventController implements Serializable { @Inject private Conversation conversation; ... public String createFormEvent() { conversation.end(); return "events?id=" + form.getId() + "&amp;faces-redirect=true"; } } </code></pre> <p>so basically I want a button that when clicked will end a conversation, and then redirect to a new page...</p> <p>this works ONCE, then every time after I see the following in my logs.. (from the users point of view, everything worked properly.. when the button is clicked, the redirect works properly)</p> <blockquote> <p>SEVERE: java.util.ConcurrentModificationException at
