[rules-users] Multiple relationship in rules problem

[Fnu Mahalakshmi]

Hi guys,

I want to work out a one to many relationship in my rules

I have 2 classes:
A{
ArrayList<B>blist;
status
}
B{
Status}
If A points to {B1,B2,B3}
If B1 exists in A then B1 status = on and A status is on
And B2, B3 status is updated to on as it is also associated with A

I am unable to depict this in my rules.
How can I traverse through lists in my rules.

I tried this::
when
    $a : A()
    $b : bList from $A.ipList
    exists (B( status == "on") from $b)
then
    modify ($a) {setStatus("on")};
end

But above doesn't work. I guess its because $b is just a variable and I am passing a list.
But not knowing how to do it.

Please help!!! Or is there any other way to go about it???

Thank you.

M
