In http://docs.jboss.com/seam/reference/en/html/conversations.html#d0e2697 it
states that:
anonymous wrote : nested conversation has its own conversation context, and
also has read-only access to the context of the outer conversation. (It can
read the outer conversation's context variables, but not write to them.)
This is convenient. However, how would you do the following:
Component A has a field that holds a foreign key reference.
User can search for the foreign key by clicking a button. That button kicks
off a search action on Component B - I currently have it as a s:link with
propagation="nest". At this point, the user is able to enter some data to help
them find the foreign key they are interested in. It displays a list of
foreign keys with a select button next to each. When they click one of the
select buttons, I want the nested conversation to end, the selected foreign key
to be propagated back to the parent conversation, and the user to be taken back
to the parent screen. My thoughts were to have the following in the select
action:
| @End
| public String selectForeignKey()
| {
| if ( this.foreignKeys==null )
| {
| return "findForeignKey";
| }
| setForeignKey();
| Conversation.instance().pop();
| Contexts.getConversationContext().set("foreignKey", foreignKey);
| return Conversation.instance().redirect();
| }
|
However, as expected, this does not work. I've tried a few other varieties of
the above with no success. Thoughts?
On a side note, because the conversation is nested, Component B allows the user
to kick a cancel link that causes a pop & redirect. This is incredibly simple.
I was hoping that the selection logic would be just as simple.
