Hello,
I have a SFSB1 - it has an a field that is marked @In @Out. This same bean has
an @Observer method that listens for an event raised by another SFSB2.
Here is the trouble I am having. In a conversation, I click a link which
invokes a method on SFSB2 - this method in SFSB2 is annotated with
@RaiseEvent("MyEvent"), which SFSB1 is 'Observing'. When the
@Observer("MyEvent") method gets invoked (due to the event), SFSB1 is throwing
a NullPointerException on the field marked @In @Out.
| 09:28:35,015 ERROR org.jboss.seam.exceptions.DebugPageHandler - redirecting
to debug page
| org.jboss.seam.RequiredException: @Out attribute requires non-null value:
realmManager.application
| ....
|
When I coded this, I assumed that @RaiseEvent would fire after outjection
occurs on the SFSB1 method - i.e.
invoke SFSB1 method
- @In occurs
- method proceeds
- @Out occurs
- @RaiseEvent fires
from the exception, this looks like what is actually happening is:
invoke SFSB1 method
- @In occurs
- method proceeds
- @RaiseEvent fires
- @Out occurs (?)
Is this second case what is actually happending? If so, isn't the first case a
better way to go if you want to have bijection work with raise+observe events?
Thanks
