[jboss-user] [JBoss Seam] - Handling nested conversations [newbie]

[jlemoine]

Hi,

this is quite basic but I can't find resources on that :

I'm running into trouble with conversation contexts.
Imagine the following -classic- scenario involving State and Country entities:
1 - a user initiates the Create State process, and searches for the adequate Country in a drop down menu.
2 - since the Country does not exist yet, he clicks the "New Country" button
 to launch the Create Country child process.
3 - the country created, the app resumes the Create State process, and why not pre-selects the newly created country in the (updated) menu.

This is so basic that I couldn't find anything on that.
The Seam Issue example handles sub processes, but is not self explanatory and doesn't work ("conversation ended"...).
I've seen that the login procedure does that, but I can't imagine putting interceptors everywhere.
Last, I've browsed the javadoc and found stuff like Conversation.endAndRedirect() but I really don't know how to use that.

I've poked around with @Begin(nested=true) annotations and the like, without success ("conversation ended ..." at best).

Is there any simple tutorial for that use-case, guideline, best practice?...

Thanks in advance,

Jean
