[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-1020) Configurable Drools event listeners (primarily for debug logging)

Christian Bauer commented on JBSEAM-1020:
-----------------------------------------

Now I get an exception in the logging... also found this in the Drools docs:

        new WorkingMemoryLogger( ((RuleBasedIdentity)identity).getSecurityContext() ) {
            public void logEventCreated(LogEvent logEvent) {
                System.out.println("### DROOLS: " + logEvent.toString());
            }
        };

1. We need to tell the Drools guys that implementing a sensible toString() method on their logEvent is a good thing.

2. The logger wants to convert stuff to cast objects in my working memory (a model.User instance in this case) to org.jboss.seam.security.Role:

> I want to see what is going on when my rules are evaluated, according to the Drools docs this is how:
>                 workingMemory.addEventListener( new DebugWorkingMemoryEventListener() );
> I have to do that in code right now, would be nice to be able to configure the identity component externally in config file. It also doesn't work, at least not in JBoss with a WAR deployment. I don't see any debug printed on System.out. Task: Ask the drools guys how we get logging for Seam users.
