my<br>
LHS of the rule. I am using eclipse. For some reason when I refer to this<br>

its setters and getters can be seen on the RHS of the rule. I get an error<br>

Anyone seen this before? It's basic drools but I just can't find a solution<br>
to this. It works for my other classes, and I can't see whats been done<br>
differently here! Help please! See code below:<br>
<br>
DRL:<br>
package com.nathean.rules<br>
import com.nathean.rules.Decision<br>
rule "Your First Rule"<br>
when<br>
$id :
Decision(custPointer == 0)<br>
then<br>
$id.getCustPointer();<br>
System.out.println();<br>
<br>
end<br>

Java Class:<br>
package com.nathean.rules;<br>
public class Decision {<br>
private int custPointer;<br>
/**<br>

public void setCustPointer(int custPointer) {<br>

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