2. Re: Seam events question
Ok, then maybe i am doing s.th. wrong, because in my case that seems not to work or this is a JSF "problem" i am trying to set some value onto a component binding when that event is fired, so i annotated the setter with
@Observer("event")
but when the method with
@RaiseEvent("event") is fired, the Setter is not called ...
Do you have any ideas, or maybe that's impossible? -
3. Re: Seam events question
You'll need to use your debugger to see where the event is lost.
Or open a JIRA and attach an example with reproduction steps so we can take a look. -
4. Re: Seam events question
Most commen error is to forget to declare the Observer method on the interface, if it's a SessionBean.

5. Re: Seam events question
I followed gbc's advise and annotated RaiseEvent onto the method in the interface (may i didn't see this in the documentation) ... but now am facing some other problem, reflection does not seem to work. Both components the one from the web and ejb tier are session scoped, to avoid problems with instantiation (at least that's my thought ;))

Any ideas on this too? -
6. Re: Seam events question
You're trying to observe with a method which takes parameters, and not passing any, or the wrong, parameter.

7. Re: Seam events question
Pete, you're becoming sort of my new hero here, you were right!
The problem i have, that the change is not reflected in the UI after the action is executed may have s.th. to do with the JSF lifecycle i think.
I am trying to set the "current Page" to 1 on a rich:datascroller after executing a search action by fireing that event.
But that somehow does not work. Maybe i'm to late, because actions are triggered within invoke_application phase and the values are set on update_model_values phase?
Regards,
Jens
