Implicit binding and "or" CE in pattern cause ClassCastException
----------------------------------------------------------------

                 Key: JBRULES-2321
                 URL: https://jira.jboss.org/jira/browse/JBRULES-2321
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 4.0.7
            Reporter: Tihomir Surdilovic
            Assignee: Mark Proctor


This is a problem with Drools 4.0.7, it does not happen in Drools 5:

$factB.f1 is triggering a scenario where the engine creates an implicit biding to the "f1" field. 
That in conjunction with the use of "or" is triggering the problem
rule "implicit bindings test"
    when
        FactA()
        $factB : FactB( $fB : f1 )
        (not FactC( f1 == $factB.f1 ) or FactC() )   
    then
end

The exception thrown is:

java.lang.ClassCastException: com.sample.FactAShadowProxy cannot be cast to com.sample.FactB
