[news.eclipse.modeling.gmt] [MOFScript]couldn't print list element

[yeliu@xxxxxx (Ye Liu)]

Hello,
 I have a class Sca,with one attribute List<String> xxx,I want print all 
the elements in this list,I write the following statment in MOFScript.
 In the context of Sca,
 self.xxx->forEach(s:string)
	  print(s+",")
when I execute the code (of course ,this is not an empty list),none of the 
elements is printed.Does anyone knows what the problem is?


Thanks a lot!

Ye
