Rules Fact Error In Complex Condition Structure
-----------------------------------------------

                 Key: JBRULES-2045
                 URL: https://jira.jboss.org/jira/browse/JBRULES-2045
             Project: JBoss Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-core
    Affects Versions: 4.0.6
            Reporter: Hao Chen
            Assignee: Mark Proctor


We are running into a complex production rule that either doesn't work or generate errors. I debugged and it seems Drools is not using the correct fact for some segments of the rule conditions.  Steps to reproduce

1. Build the attached test case
2. Run the DroolsDefectTest junit test, it should print value "Worked!" on the output console.
3. Modify the rule by remove the commented condition that uses variable b2.
4. Run the test again. 
 Expected result: the rule should output "Worked!" again. 
 Actual result: failed with error:
