how to send events between natural conversations

[henrik.lindberg]

Hi,
If I have understood things correctly, it is only possible to send events from a conversation / scope to the hierarchy of conversations that led to the conversation that sends an event. (Is this correct?)

In my case I want to send an event from a conversation with a natural conversation id - (a conversation identified by a particular object), and I want to send the event so another natural conversation can pick this up with an @Observer (preferably).

Since the two conversations are neither nested or joined - I wonder if I can do this.

When I try, nothing happens, the @observer is never called.

Is it possible to find a conversation (since I know the conversation id) and find a particular bean (by its name) and call a method on that bean?

Any other ideas on how to get this done? (Or have I misunderstood how it is supposed to work?)

Regards

If I understand you correctly, you have conversation A and conversation B. In conversation A you have some Seam component foo, and in conversation B you have some instantiated some component bar.

bar has an observer method that listens for fooEvent. You call a method on foo, which raises fooEvent. The observer method on bar will be called, but it won't be *the same instance* of bar that you have conversation B, but rather a new instance.

You can't observe an event raised in one conversation in another. If the observer was in the session scope or application scope this would work.

ok, so, how can I achieve some sort of "global event". Basically, I just need the bean in the "other conversation" to update from the DB so it can present fresh information if the user returns to this conversation.
