nested:form parent scope

I'm using RC1, playing around with nested tag support, and ran into an unexpected behavior. I'm not sure if this is by design and I'm using it incorrectly, or a bug.

I'm iterating over a list of users, and want to create a short form for each user, containing their username and a submit button. However, I can't seem to refer to the bean created by the nested:iterate tag from within the nested:form scope. Jsp source code below.

How, from a nested:form, can I refer to a bean in the parent scope? As demonstrated below, "../" does not seem to work in this situation. Any suggestions? Workarounds? Help?

Thanks in advance,
