Extend @Scope to work on member variables/properties
----------------------------------------------------

                 Key: JBSEAM-1233
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-1233
             Project: JBoss Seam
          Issue Type: Feature Request
          Components: Core
    Affects Versions: 1.1.6.GA
            Reporter: Andrew


I have a relate bug:
http://jira.jboss.com/jira/browse/JBSEAM-903

My purpose for this bug was mostly due to binding issues. There are times that I want to have the scope of a member variable to be different from the scope of the bean. Especially, if the bean is conversational and I want the field/property to have event scope. Instead of the proposed @InOut from the above bug, perhaps just extending @Scope would work:

@Scope(ScopeType.EVENT)
private MyVar myVar;

Unlike @In and @Out, this scope would not put use the contexts to get and set values, but simply control the lifecycle of the variable. In this example, myVar could be set to null when the the variables of the bean are out-jected. As it stands, there is no other easy way that I know of to have a variable set to null at then end of a page request.
