Erm, Rule Flow springs immediately to mind.

Or you can use semaphore Facts yourself - but you're re-inventing the (Rule Flow) wheel.

rule "rule 1"

when

condition is true

then

insert(new SemaphoreFact());

end

rule "rule 2"

when

SemaphoreFact()

Some other conditions are true;

then

action

end

rule "rule 3"

when

Even more conditions

then

action

end

Subject: [rules-users] Nested Rules

Hi

I am using Drools 4.0.4 with Eclipse 3.2. I m much happy with the results. But now my application needs nested loops..

Can i write nested rules like

rule "rule 1 "         // if condition of rule 1 is true then only execute rule 2 other wise skip it

when

    condition is true

then

    execute rule2

rule "rule 2 "

when

    condition is true

then

    action

rule "rule 3"

when

      condition is true

then

     action

Thanks and Rgards
