[rules-users] Tuples in Agenda Item.

[Greg Barton]

The rule below is doing exactly what it should.  Here's the rule expressed in pseudo code:

when
  1) there's an object of type DroolsWorkingMemory
  2) there's an object of type BaseType
  3) there's an object of type ConcreteType1
  4) the BaseType object and ConcreteType1 object are equal
then
  blah, blah, blah...
end

So if you have a single ConcreteType1 object, it fits the logical conditions of the rule.  It's a BaseType, a ConcreteType1, and is equal to itself.

I don't quite understand your two issues, though.

Hi,
 
Sorry for not being very clear. Here's the rule which I run:
 
 
package rr
import com.thirdpillar.common.util.DroolsWorkingMemoryimport com.parentchild.BaseType
import com.parentchild.ConcreteType1 
 
rule "s"
no-loop true 
salience 999999 
 
when
DroolsWorkingMemory:DroolsWorkingMemory()
BaseType:BaseType()
ConcreteType1:ConcreteType1()
eval (
(
((BaseType.equals(ConcreteType1)))
)
)
then
BaseType.setString("Blah Blah!");
end 
 
where ConcreteType1 extends BaseType. 
 
Issues:
1. Even for different values for fields in ConcreteType1 and BaseType, the rule gets fired. 
 
2. I also do audit for the rules for which i need tuples so that I can extract the objects out of it and evaluate the expression against Mvel. But the tuple shows me only the ConcreteType1 instance not the BaseType. Thus getting wrong audit.

We need some rule code to get a better idea of what's going on.  Can you post some?

Hi,
 
I have a doubt regarding tuples. I created a rule using complex types objects. I am comparing two complex type objecs which have parent-child relationship eg. "ParentType.equals(ChildType)". I expect this to follow java rule which allows such comparision. Now when I run the rules with different values for fields in ParentType and ChildType (which means the rule should fail) to my surprise it evals to TRUE. Also upon inspection, the tuple shows me only the ChildType instance not the ParentType. 

 
I would appreciate any help on this.
 

Regards,

Rajnikant
