[drools-user] java NullPointerException when using constraints between fields in same object

Hi everyone, I have a another question:

The JIRA has "java NullPointerException when using constraints between 
fields in same object" in two different issues:

http://jira.jboss.com/jira/browse/JBRULES-548
http://jira.jboss.com/jira/browse/JBRULES-515

both of them are closed, and the 548 says thats it's fixed in 3.0.5. I 
have been working with the latest version from the repository and it was 
solved from sure, but now I've changed to 3.0.5 and the problem is back.
Any ideas? Maybe I'm doing something wrong: To switch to 3.0.5 I've 
downloaded the jbossrules-ide-3.0.5-bin.zip, extracted the 
org.drools.ide_3.0.5.jar jars into a lib folder, and included to the 
eclipse project.

Beto



rule "RULE TWO"

when
        Test($z :z, $y :y, $x :x, $id :id, x < $z, y == true)
then
        System.out.println("ok!");
end

java.lang.NullPointerException
