You have to change 
$c->stash->{form}->input->{'nickname' } 
to get your behaviour, but that is a hack as it relies on the internal 
behaviour of FormFu, which might change.

So Carl's way is nicer.

In general I think we should create a filter that can do this work for fields 
that takes the value of an other field, as this is a common task.

And we could create a shortcut like 'overwrite_value' to do this task in one 
function.

What do you think Carl?
