Problem when mixing alpha and beta constraints in a composite constraint
------------------------------------------------------------------------

                 Key: JBRULES-1472
                 URL: http://jira.jboss.com/jira/browse/JBRULES-1472
             Project: JBoss Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 4.0.4
            Reporter: Edson Tirelli
         Assigned To: Edson Tirelli
             Fix For: 4.0.5, 5.0.0-M1


REPORTED BY Jai Vasanth

The first case
rule "Remove smaller or non-overriden"
    dialect "java"
    when
        L : Response( $r : value && status != "override" )
        (Response(  value > $r ) or Response( status == "override"))
    then
        retract( L );   
end


breaks down to

rule "Rule1"
    dialect "java"
    when
        L : Response( $r : value && status != "override" )
        Response(  value > $r )
    then
        retract( L );   
end

and

rule "Rule2"
    dialect "java"
    when
        L : Response( $r : value && status != "override" )
        Response( status == "override")
    then
        retract( L );   
end


I see that the first rule removes all objects with smaller values and the second one removes all the ones that arent overridden if there exists an object that has an override


What I dont understand is, why the second one doesnt have similar behaviour


rule "Remove smaller or non-overriden"
    dialect "java"
    when
        L : Response( $r : value && status != "override" )
        Response(  value > $r ||  status == "override" )
    then
        retract( L );   
end

When this rule runs , it should start removing objects with smaller values that are *not* overridden .  So if an overridden object exists finally we will be left with 2  objects

Response( maxvalue, non override status ) and Response( somevalue, "override" )

When the rule fires now  L will take on the first one and the the other object will match the second one since it has an override even though value  <= $r . This L should be extracted and we should just be left with the overridden object.

But  I still seem to be left with both the objects.
