Hmmm.... this kinda makes sense to me, only it didn't work. The proposed?
method works correctly, but the can? method in my template returns true for
both proposed and non-proposed ProposalRequests. I'm having a hard time
getting my head around validating a Proposal against it's parent when the
Proposal hasn't even been created yet.
Thanks,
Stan
