Well I don't want to render the field in the backend. I need to set a
value based on user input when the record is saved. With 'type' =>
'user' I could set the value of an input field. I could make that
read only but the value would be set when the form is displayed, not
when the user saves the record. Setting the value when the user saves
the record is importnat because it's based on the value of another
field (not yet known when the form is displayed).

Thanks anyway,
Attila
