[rules-users] Facts - can they be non Java Beans

[sridhar123]

I am trying to access Fact objects that are not always java beans. Example:

Class A {
  Arraylist  Class B b

  getFirst() { return b.first() }

  }

In above Class i dont have any variable called "first" - but returning first
element of the list.

Now following DRL throws compilation errors. 

rule "Some Rule"
  when
        $MyFact :A()
     	$first : $myFact.getFirst() 
   then
       ....
       ....
end

Is there any way to execute the above - or i should have class variable
"first" and access that?

thank you
Sridhar
