FactTemplate Property Access leads to RuleBuilder Exception
-----------------------------------------------------------

                 Key: JBRULES-1438
                 URL: http://jira.jboss.com/jira/browse/JBRULES-1438
             Project: JBoss Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Drl Parser/Builder
    Affects Versions: 4.0.4
            Reporter: greywind
         Attachments: EntityTest.drl

The only thing I do is to add the attached drl to a Package and do get the following exception:
