[Matt Green (JIRA)]

Using a GLOBAL value in predicates in more than one rule - rule fails to evaluate correctly.
--------------------------------------------------------------------------------------------

                 Key: JBRULES-505
                 URL: http://jira.jboss.com/jira/browse/JBRULES-505
             Project: JBoss Rules
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: All
    Affects Versions: 3.0.4
         Environment: Windows XP, JBoss 4.0.3SP1, JRules3.0.4, PackageBuilderConfiguration.JANINO
            Reporter: Matt Green
         Assigned To: Mark Proctor


SAMPLE CODE:
===============================================
package net.rockshore.rmf.rules

#list any import classes here.
import net.rockshore.rmf.entities.SubscriptionLocal;
import net.rockshore.rmf.entities.EventLocal;
import java.lang.String;

#declare any global variables here
global java.util.Collection resultsCollection;
global java.lang.String eventType;

rule "KeepSubscriptionsToEventType"
	
	when
		subscription : SubscriptionLocal (eventTypeDiscriminator == (eventType))
	then 
		resultsCollection.add(subscription);
		System.out.println("Keeping Subscription:" + subscription + " is of type:" + eventType);
		
end

rule "DiscardSubscriptionsToWrongEventType"
	when
		wrongSubscription : SubscriptionLocal (eventTypeDiscriminator != (eventType))
	then 
		System.out.println("Discarding Subscription:" + wrongSubscription + " NOT of type:" + eventType);
		retract (wrongSubscription);
end

===============================================

TEST DATA SET:
-------------------------

SubscriptionLocal objects asserted
key                                                                                eventTypeDiscriminator
---------------------------------------------------------------------------------------------------------
5c4o12-mexdpy-esmukytr-1-esmx439o-58         net.rockshore.rmf.entities.events.business.TravelAlertEvent
5c4o12-mexdpy-esmukytr-1-esmx438t-57          net.rockshore.rmf.entities.events.business.FlightDelayEvent
5c4o12-mexdpy-esmukytr-1-esmx438t-56          net.rockshore.rmf.entities.events.business.FlightDelayEvent

eventType = "net.rockshore.rmf.entities.events.business.FlightDelayEvent"


PROBLEM DESCRIPTION:
-------------------------------------
When firing the above rules with data shown above, the result shows that "DiscardSubscriptionsToWrongEventType" rule was fired for Subscriptions with keys ending 57 and 56. This is the wrong way round as that rule should have fired only with Subscription 58.

Further, rule "KeepSubscriptionsToEventType" did not fire.

FURTHER ANALYSIS:
-------------------------------
If one rule OR the other is deleted then the remaining rule fires correctly.

If both rules have the predicate replaced with a String literal "net.rockshore.rmf.entities.events.business.FlightDelayEvent" then both rules fire correctly.

The problem still occurs when eventType predicate is replaced with eventType.toString()
