I'm facing a problem where the object hasn't yet been committed to the db
and there for the object has no id. This is probably the root of this
exception.
I'm trying to build an ajax wizard where each step has it's own ajax form
and the db commit will be handled at the end. I was hoping to just pass in
the value form form A into the context of form B, but that may not be
possible without an id.
I suppose I could use @SessionState or in the past I've copied the form
data from form a to form b and sent the original form data out of view, but
I've been hoping to come up with a better solution than those two since
processing form A data requires a lot of system resources.
