Good question, I was sure someone would ask me that :-]
As I said in my example, I have a form that is instantiated in several
pages. This forms has a field 'updated_by' that contains the ID of
current user (according to session data)
So, it's better - I think - to write only one time "setDefault
('updated_by', 'value');" within the form instead of writing it each
time you instantiate a new form. (and the developper may forget to set
the value...).
I think this is a good reason, at least, there should be a way to do
it...
