To get this behaviour, set 'render_processed_value' to a true value.

You can set this at the form level to effect all fields, or set it at
the fieldset- or field-level.

One thing to beware is if you have Inflators on a field that create an
object, you'll need to ensure either that the object stringifies
correctly, or set "render_processed_value = 0" for that particular
field.
