[rules-users] Error using forAll() in rules

Hi, I have a list of items which I want to modify if condition turns true. I tried forall but its not working:: A{ String Name } B{ A a, } Rule " modify B if A name = 'bob'" when forall($a : A() $b : B( a == $a) ) then modify($b){ seta($a.getName())}; I have many B objects pointing to same A object and when name of A is modified I want the rule to fire and all B to also be modified. What is wrong above??? I tried this too: when forall($a : A() B( a == $a) ) then modify($b){ // but then I cannot do this step.which is required seta($a.getName())}; Any Idea???
