Hi milesif,
the problem you are facing is due to a misunderstanding of the Seam explicit
conversation id feature, and it worked before the 1.2.1GA for a missing check.
I know it very well because happened to me too, what you expect to do
specifying:
@Begin(id="", join=true)
is wrong (better, not conforms to the Seam conversation management), because
you want to switch between LRCs and this is not possible, indeed, you can start
a new long running conversation *only* out of any other LRC.
What happens now in your code (and you can see it watching the debug
information of your server) is: Seam intercepts that you are trying to make
concurrent calls and creates a temporary conversation and does not promote it
at the end of the request... but trashes.
If your design allows it, you can avoid it avoiding to propagate the
conversation when you want to start a LRC in a way similar to:
| <s:link action="#{machineManager.start}" value="...">
| <s:conversationPropagation type="none" />
| </s:link>
|
if you don't want to end the conversation you are in (none does not end the
conversation you are leaving, then you can refer to that LRC later, but not
arriving from a LRC :) ).
Moreover, you should plan to migrate to the new business key way to define the
explicit conversation ids in a natural way (this because id definition in the
@Begin could be deprecated really soon), this is not officially released and
undocumented, but if you want have a glance see:
