Well, OK, I'm sorry everyone, I should have been more clear:
The goal that I have is to make a snippet that creates a templated
edit form for me. However, this is not the >issue< which I want to
discuss. The issue is that when I try to make this snippet (and this
could have been any snippet, since the principles are the same), I am
unable to, because somewhere the instance of the Mapper for which I
want to create the snippet (in this case it's a MetaMegaProtoUser)
gets lost, and thus no changes are preserved. The reason why I
mentioned the templating in the first place is because I basically use
exactly the same code as in the default MetaMegaProtoUser.edit method,
just adding some bind calls and an extra parameter: the template
NodeSeq, and suddenly the code breaks. As mentioned before, any
changes I make in the client aren't saved. I have no good way of
checking whether the changes even are contained within the POST(→it's
the localForm's fault) or if the User instance gets lost earlier
(→it's some closure that fails somewhere), but the testEdit function
gets called for sure, but with the wrong user instance.
Hopefully I've made my problem more clear.
