[rules-users] no-loop and update vs. PropertyChangeListener
Hi,
I'm running the StateExampleUsingSalience example. It uses a fact with
PropertyChangeSupport.
AFAIUI I don't have to call update() every time I modify this fact in
the RHS, when I want to have my rules to be reconsidered.
I've modified the drl to look like this:
rule "a"
no-loop true
when
b : State(name == "B", state == State.NOTRUN )
then
System.out.println(b.getName() + " finished" );
b.setState( State.FINISHED );
System.out.println(b.getName() + " finished 2" );
b.setState( State.NOTRUN );
end
When I insert a State object (name="B", state="State.NONE"), this rule
would run forever if no-loop wouldn't be set to true. Unfortunately I'm
wrong. If I want to have no-loop working I need to provide update()
after b.setState().
So it looks like PropertyChangeSupport doesn't cancel an activation,
like update() does.
Thanks,
Jarek
