@PostConstruct called multiple time for @ConversationScoped bean

I have a @ConversationScoped bean using the start method, for example:

@PostConstruct
public void start() {
    if (conversation.isTransient()) {
        conversation.begin();
        log.debug("conversation.getId(): " + conversation.getId());
    }
}

My problem is that every time the page is refreshed, a new conversation starts, a new conversation also starts every time I have an AJAX call to a method in a bean (which is my main problem).

What I really want to do is that the chat chat hangs until I manually call chat.end (). What am I missing here?

Have you verified that calls (AJAX) include a conversation identifier (cid) parameter?

If this is absent, it is expected that a new conversation will begin for each call.
