This is in Drools 4.0.7
I have a class called SatManager with a field:
ArrayList<Satellite> listOfOverheadSats
That has an appropriate getter method.
I have a relatively simple rule that goes something like this:
when
$sat : Satellite(isOverhead == true)
$sm : SatManager($ls : listOfOverheadSats not contains $sat)
then
$ls.add($sat);
My problem is that Drools doesn't understand that the ArrayList has been
modified, therefore this rule always fires on the same satellite if the sat
object changes in any other way.
I've tried adding:
update($sm);
To the consequence, but that only caused the rule to re-fire infinitely -- even
with the no-loop keyword applied.
So my question is how does Drools manage its knowledge of changes to
Collections embedded in fact objects? The documention for the 'contains/not
contains' keyword did not explain this.
I'm really stumped here.
