What attribute differentiates A1 from A2?
Such scenarios usually are solved by an additional constraint...

Hi guys,
Now I am strugglin' with "fact id checking" or whatever we can call
it.... :D
Let's take into account the followong scenario:
I have class A (it's just a name) javabeans to be inserted into the WM.
I define two objects of class A: A1 and A2.
Somewhere I do "insert(A1)" and "insert(A2)" ( let's say I do it
in the
same package of R1 and R2..see below...)
Then I define two different rules R1 and R2 that reason over class "A"
facts (let's say R1 and R2 are in the same package) .
The point is.... I want R1 to fire only on A1 and R2 only on A2.
Is that possible in drools? Is there a sort of "fact id" I can reason
over?
I do not think globals will be of any help, cause in the guide i have read
that globals should never be used within LHS.
We should never reason over globals.
Let me know.
Massi
