Hello,

I am very new to drools. I am having trouble with rule syntax.

I have an object A. One of the fields in class A is a reference to an object B.
class A
{ private B;
int x;
//getters and setters and stuff
}

class B
{ int y; }

I have a bunch of objects of class A in working memory.

Now, I want to write a rule that says "if A.getB().getY() == 10, then A.setX(4)".

What is the code for this rule? (I'm NOT using xml)
