Hi,

I am running 3.1-M1 and have (by way of example) two simple rules; A and B as follows:-

rule "A"
when
        $a1 : Attribute ( name == Constants.ATTRIBUTES_A, $pa : number )
        $a2 : Attribute ( name == Constants.ATTRIBUTES_B, $nc : number )
        $p : Process ( attributesList contains $a1, attributesList contains $a2 )
then
        double txy = doSomeMaths($pa, $nc, $p);
        Attribute a = new Attribute(Constants.ATTRIBUTES_C, txy);
        $p.addAttribute(a);
        assertLogical(a);
        modify($p);
        System.out.println("Rule 'A' fired");
end
                       
rule "B"
when
        $a1 : Attribute ( name == Constants.ATTRIBUTES_C, $txy : number)
        $p : Process( attributesList contains $a1 )                             // <-- Line causing rule not to activate

then
        double m = doSomeMoreMaths($txy, $p);
        System.out.println("Rule 'B' fired");
end

Process exposes an ArrayList of Attribute objects (each having a name\value pair).

When the content of the ArrayList held by Process is added to (Rule 'A') the next rule (Rule 'B') is not being activated.

Can anybody provide any insight into how best a workaround can be engineered?

With kind regards,

Mike
