> REPORTED BY TOM GONZALEZ:
> ---------------------------------------------
> We are asserting facts that support property change listeners and found that Drools added itself as a listener just fine but failed to remove itself when the facts were retracted.
> We have fixed the stated problem by modifying org.drools.common.AbstractWorkingMemory as follows:
> Starting at line number 582:
> protected void removePropertyChangeListener(final FactHandle handle) throws NoSuchFactObjectException {
>         Object object = null;
>         try {
>             object = getObject( handle );
>             final Method method = object.getClass().getMethod( "removePropertyChangeListener",
>                                                               AbstractWorkingMemory.ADD_REMOVE_PROPERTY_CHANGE_LISTENER_ARG_TYPES );
>             method.invoke( object,
>                           this.addRemovePropertyChangeListenerArgs );
> Regards,
