I figured what was wrong - I did not convert my project into Drools project and the debug profile was not starting it as a Drools application. Once I did that - I could see the objects in all views.

I use Eclipse 3.3 with JBoss Rules 4.0.7 plugin. I'm trying to debug my rules , but no matter what breakpoints I set I can never get anything in the Working Memory or Agenda views. I tried setting a normal Java breakpoint on the session.fireAllRules() method -- it stops before calling the method, I select the session variable in the Debug Variables view - but nothing is displayed in the Working Memory view. I even tried to step into the fireAllRules() method - but the Working Memory view is empty at all times. Then I tried to set a rules breakpoint in a "then" part of my rule - this time Eclipse does not even stop there, instead, it stops on the statement after the call to the fireAllRules() method. Do I have something mis-configured?? thanks, Marina
