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.
