[rules-users] Bulk modification

[Rodrigo Goncalves]

Hi,

How can I modify all objects resulted from a collect operation?

I would like to do something like this: (The following does not work)

rule "test"
  when
        exists (MyClass());
        $l : ArrayList() from collect (MyClass (attribute == false));
        $r : AnotherClass();
  then
        $r.doSomething($l);
        for(Object o : $l) {
                MyClass o2 = (MyClass) o;
                modify(o2) { setAttribute(true); } ;
        }
  end


I do not want to do:
rule "test"
        when
                $o : MyClass(attribute == false)
                $r : AnotherClass()
        then
                $r.doSomething($o);
                modify(o) {setAttribute(true);};
end

because I need to do a bulk operation… Doing it one by one is extremely 
inefficient in my case.

Thanks!

Rodrigo.
