             Summary: Rule inheritance fails when using or pattern binding
                 Key: DROOLS-570
                 URL: https://issues.jboss.org/browse/DROOLS-570
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
         Environment: Windows 7 VM. Running drools using a JUnit driver
            Reporter: Eugene Shvartsman
            Assignee: Mark Proctor


I've found a certain combination of rules (when using inheritance) that causes drools to throw the following exception: http://pastebin.com/xxq5ZtAC 

The rules that cause this exception to occur can be found here: http://pastebin.com/wM6rWY8L

I've simplified my original rules down to the lowest level of detail that still throws the exception. The exception is no longer thrown if I: 
1. Don't use rule inheritance 
2. Don't have an or statement 
3. Don't reference an LHS defined variable in the RHS of ruleB
