Re: [rules-users] Rules fired without calling session.fireAllRules()

Hi,
I have the following code, which is not working as I expected.
rule "New AlertFacade"
salience 1140
when
$af : AlertFacade();
then
System.out.println($af.getProperties());
end
In the java code:
while (!isFireAllRules)
{
session.insert(alertFacade);
....
}
session.fireAllRules();
But I am seeing the rule "New AlertFacade" is fired everytime I inserted
the
fact. Shouldn't it wait until fireAllRules() be called? Am I missing
something
here?
The "when' is evaluated as Drools builds its RETE network, which happens as
soon as you insert() the fact. This is called the LHS.
The "then" should happen only after you issue "fireallrules()". This
is also
called the RHS of the rule.
If you see the system.out prints before you call fireallrules check that
your not using some eval in another rule in the LHS that might cause the
system.out calls.
Thanks,
Jin
