<div><font face="Arial" size="2">Hi guys,</font></div>
<div><font face="Arial" size="2"></font> </div>
<div><font face="Arial" size="2">Now I am strugglin' with "fact id checking"
or whatever we can call it.... :D</font></div>
<div><font face="Arial" size="2"></font> </div>
<div><font face="Arial" size="2">Let's take into account the followong
scenario:</font></div>
<div><font face="Arial" size="2"></font> </div>
<div><font face="Arial" size="2">I have class A (it's just a name) javabeans to be
inserted into the WM.</font></div>
<div><font face="Arial" size="2"></font> </div>
<div><font face="Arial" size="2">I define two objects of class A: A1 and
A2.</font></div>
<div><font face="Arial" size="2"></font> </div>
<div><font face="Arial" size="2">Somewhere I do "insert(A1)" and "insert(A2)" (
let's say I do it in the same package of R1 and R2..see below...) </font></div>
<div><font face="Arial" size="2"></font> </div>
<div><font face="Arial" size="2">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)
.</font></div>
<div><font face="Arial" size="2"></font> </div>
<div><font face="Arial" size="2">The point is.... I want R1 to fire only on A1
and R2 only on A2.</font></div>
<div><font face="Arial" size="2"></font> </div>
<div><font face="Arial" size="2">Is that possible in drools? Is there a sort of
"fact id" I can reason over?</font></div>
<div><font face="Arial" size="2"></font> </div>
<div><font face="Arial" size="2">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.</font></div>
<div><font face="Arial" size="2">We should never reason over globals. </font></div>
<div><font face="Arial" size="2"></font> </div>
<div><font face="Arial" size="2">Let me know.</font></div>
<div><font face="Arial" size="2"></font> </div>
