[Mark Proctor (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBRULES-445?page=all ]

Mark Proctor closed JBRULES-445.
--------------------------------

    Resolution: Won't Fix

java is pass by reference, you cannot change the value of a global this way. Please consult the mailing lists if you continue to misunderstand this.

>                 Key: JBRULES-445
>                 URL: http://jira.jboss.com/jira/browse/JBRULES-445
>             Project: JBoss Rules
>          Issue Type: Feature Request
>      Security Level: Public(Everyone can see) 
>          Components: Drl Parser/Builder
>    Affects Versions: 3.0.4
>            Reporter: G?bor Lipt?k
>         Assigned To: Mark Proctor
>            Priority: Minor

> It seems that the value of DRL globals without external env backup is removed between rules:
> package globaltest
> import Policy;
> global java.lang.String text;
> rule "Foo"
> 	salience 999
> 	when
> 		Policy()
> 	then
> 		text="foo";
> 		System.out.println("foo+"+text);
> end
> rule "Bar"
> 	salience 998
> 	when
> 		Policy()
> 	then
> 		System.out.println("bar+"+text);
> 		text="bar";
> 		System.out.println("bar+"+text);
> end
> results in:
> foo+foo
> bar+null
> bar+bar
> The documentation does not seem to provide details if this is the expected behavior. 
> Please comment. Thanks
