Auto generating a sequence diagram from code

[seamoh]

Hello  all,
I tried  Auto generating a sequence diagram from code by using enterprise architect , I searched in the internet and I found this article in a blog:
http://blogs.imeta.co.uk/TPeplow/archive/2009/03/11/auto-generating-a-sequence-diagram-from-code.aspx
as the article says , we should import our code in enterprise architect , (project --->source code engineering --->import actionscript files)
then we should write on a method , and it shows "Generate sequence Diagram " option , when I write clcik on the mehtod , I don't see "Generate Sequence Diagram " option .
I appreciate any help
