The long explanation is something like this: Idea: Select and edit an entity bean, in a conversation I have a h:dataTable with buttons which have a seam like action method (el enhancement). The backing bean is annotated to start a conversation if the method is called. The first conversation is started and you get redirected to the an "edit" page. Here you can edit the attributes of the object. So I was able to implement the direct attributes. Now I tried to start a nested conversation to select the Master-Detail related entities. But this on an ajax (a4j + richfaces) enabled site. Do you need some code? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4056745#...
