> I have a rule which checks variables of two equal objects in an old and a new version. If I work with the variable daclaration $nd1 then the consequence is NOT executed although it should.
> This is the version of the rule in that the consequence is not executed although it should: 
> ------------------------------------------
> package apm.event.resource;
> #list any import classes here.
> import java.util.*;
> import de.fraport.test.*;
> #declare any global variables here
> global Collection results;
> rule "Test-Del"
> 	salience 900 
> 	when
> 		#conditions
> 		TestMainObjectPair( $omo: oldMainObject != null, $nmo: newMainObject )
> 		TestObject( date1 == null, $od2: date2 != null, $os1: strVal1 != null ) from $omo.testObject
> 		TestObject( $nd1: date1 != null || date2 != $od2 || strVal1 != $os1 ) from $nmo.testObject
> 	then 
> 		#actions
> 		System.out.println("****** Executing consequence of rule Test-Del nd1="+ $nd1 +" ...");
> 		results.add($nto);
> end
> ------------------------------------------
> This is the rule version which delivers the expected result (without using $nd1):
> ------------------------------------------
> package apm.event.resource;
> #list any import classes here.
> import java.util.*;
> import de.fraport.test.*;
> #declare any global variables here
> global Collection results;
> rule "Test-Del"
> 	salience 900 
> 	when
> 		#conditions
> 		TestMainObjectPair( $omo: oldMainObject != null, $nmo: newMainObject )
> 		TestObject( date1 == null, $od2: date2 != null, $os1: strVal1 != null ) from $omo.testObject
> 		$nto: TestObject( date1 != null || date2 != $od2 || strVal1 != $os1 ) from $nmo.testObject
> 	then 
> 		#actions
> 		System.out.println("****** Executing consequence of rule Test-Del nd1="+ $nto.getDate1() +" ...");
> 		results.add($nto);
> end
> ------------------------------------------
> If wished, I have a corresponding JUnit test case for this issue.
