@Begin(join=true) isn't making the conversation last longer

nepoez79 Jul 31, 2006 1:00 PM

I have a method in my class:

@Name("inbox")
@Scope(ScopeType.CONVERSATION)
public class InboxActionBean {
 @Begin(nested=true)

 MyObject obj;
 public void init(){
 if(loaded==null){
 obj = search();
 }
 }

...

this init() method is called using page action. It works fine, the page renders with the data in MyObject. However any subsequent actions I call will cause a nullpointer because obj is null. This makes me think the conversation already ended after one request. I removed any @End annotaions and still the same..

I've got other conversations to work before but those conversations are @Begin(join=true, pageflow = "somePageFlow")

I'm trying to create a conversation without using page flows.

Thanks

actually the conversation is started, as when I go to other pages in the same conversation using <s:conversationId/> in my output links the obj is still available so I know I'm in the conversation.

However on the page when I do posts, just with a simple <h:commandButton action="#{inbox.search}" value="#{messages.SEARCH}" />

I get the following exception... Am I supposed to have some hidden field for the conversationId here? Seems like the conversation is lost when I press this button.

Another thing I don't understand is that I actually tried taking out the <s:conversationId/> in my outputlinks and still the following pages were able to continue the conversation... Although this is a separate problem from the original post

I'm also noticing in the address bar of the browser, the conversationId often changes numbers when I do a post. However, outputlinks with <s:conversationId/> stay put. Even though I'm not even sure why I use it since when I don't use it the conversation still seems to be active despite the fact that the conversationId changes on the address bar.

Ok, the no conversation conext error is the same as described. So as long as I don't bind anything to a conversation scoped object it's fine. Although I didn't see that in the FAQ section.

http://www.jboss.com/index.html?module=bb&op=viewtopic&t=81880

However I'm still boggled about why my GET requests work and still contain data from the conversation even when I don't specify a "conversationId" param in the link.
