[rules-users] Double Handling

[Ade Timi]

I tried changing the name to anything but the same problem persists.

It seems that Drools is confused by the usage of the class name "Decision"
(which is used in the core: java/org/drools/jpdl/core/node/Decision.java

I can reproduce a similar effect, simply by renaming a class in a working
example
to "Decision".

I still haven't gotten any break through with my problem. The issue is my
LHS of the rule. I am using eclipse. For some reason when I refer to this
particular java class and its variables they can't be seen by the rule but
its setters and getters can be seen on the RHS of the rule. I get an error
saying:
BuildError: Unable to create Field Extractor for 'custPointer' of
'[ClassObjectType class=com.nathean.rules.Decision]' in rule 'Your First
Rule'

Anyone seen this before? It's basic drools but I just can't find a solution
to this. It works for my other classes, and I can't see whats been done
differently here! Help please! See code below:

DRL:
package com.nathean.rules
import com.nathean.rules.Decision
rule "Your First Rule"
       when
               $id : Decision(custPointer == 0)
       then
               $id.getCustPointer();
               System.out.println();

end

Java Class:
package com.nathean.rules;
public class Decision {
       private int custPointer;
       /**
        * @param customerPointer the customerPointer to set
        */
       public void setCustPointer(int custPointer) {
               this.custPointer = custPointer;
       }
       /**
        * @return the customerPointer
        */
       public int getCustPointer() {
               return custPointer;
       }
}

Any update on this? (My last guess - no update - seems to be the only
reasonable explanation, so I'm curious.)
