[Gavin King (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBSEAM-1757?page=all ]

Gavin King updated JBSEAM-1757:
-------------------------------

    Fix Version/s: 2.0.0.CR1
         Assignee: Gavin King
         Priority: Major  (was: Minor)

Yes, the reason is that BijectedMethod is not a get/set pair. Fixing this will require a little bit of a redesign, I guess.
