> Hello,
> I'm trying to reference a global in an accumulate block and I get the following error : 
> Rule Compilation error : [Rule name=Hello World, agendaGroup=MAIN, salience=0, no-loop=false]
> 	org/drools/examples/Rule_Hello_World_0.java (15:338) : Syntax error on token ",", delete this token
> 	org/drools/examples/Rule_Hello_World_0.java (41:1544) : Syntax error on token ",", delete this token
> Here is a sample drl file base on the HelloWorld.drl (found in the drools samples)
> ---------------------------------------------------------------------------------------------------------
> package org.drools.examples
>  
> import org.drools.examples.HelloWorldExample.Message;
> import java.util.*;
>  
> global Message globalMessage;
> rule "Hello World"
> 	when
> 		$msgList : List() 
>         	from accumulate( $msg : Message(),
>                              init( List result = new ArrayList(); ),
>                              action( if (globalMessage.getMessage() == $msg.getMessage()) result.add($msg); ),
>                              result( result ))
> 	then
> 		System.out.println("Size: " +  $msgList.size() );  
> end
> ---------------------------------------------------------------------------------------------------------
> If I use 
> action( if ("Hello World" == $msg.getMessage()) result.add($msg); ),
> instead of 
> action( if (globalMessage.getMessage() == $msg.getMessage()) result.add($msg); ),
> it's working great...
