Spock Grails 2.0 Forward Not returning Model data
===

I am trying to test a Grails 2.0.4 controller Using Spock plugin

--------------------Controller-------------------

def addComment= {
		
		
		def pageCounter=0
		
		def result=reviewService.addComment(params.copyId,params.comment)
				
		forward(action: "showPage", model: [copyId: result.copy.id,pageCounter:pageCounter])
		
	}

==================Controller test============================

@TestFor(ReviewController)
class ReviewControllerSpec extends ControllerSpec
{

def "test"() {
		
				
		setup:
                       -------------
 
                when:
                       -------------
                       def returnMap=controller.addComment()
 
                then:
                       mockResponse.forwardedUrl=='/grails/review/showPage.dispatch'


} 


------------------------------------------------

The Test passes but i am not able to get the return parameters defined in the controller forward 

forward(action: "showPage", model: [copyId: result.copy.id,pageCounter:pageCounter])

Can you please help me and let me know how to get the return parameters 'copyId' and  'pageCounter' in my Spock Unit Test.
I have printed the values (both the above variables) in the Controller code and they have data in them.I have looked into 'forwardArgs' ,'mockResponse' etc..
Please Help
 
Thanks
Regards
