this may not be exactly what you were asking for, but one option is to
separate the record retrieval logic and the form display so that you end
up with something like this
my-form.html
<%init>
my %form_args;
if ( $this_an_existing_record ) {
%form_args = My::DB::Module::retrieve_record( %db_args );
} else {
%form_args = My::DB::Module::set_defaults();
}
$m->comp( 'form-display-component', %form_args );
</%init>
now whatever you have populated %form_args with gets passed "naturally"
into your form. you could even integrate the logic for determining
whether this is an existing record into the method that you call to
populate %form_args, leaving you with
<%init>
my %form_args = My::DB::Module::retrieve_record( %db_args );
$m->comp( 'form-display-component', %form_args );
</%init>
the bottom line is that by separating the data retrieval and the form
display allow you to leverage the mason code for setting the local
variables. the problem is that this code happens before <%init> (look in
the obj files sometime) so mangling %ARGS doesn't change the values for
the already-set local variables. you could just ref to your variables
directly as $ARGS{field1}, $ARGS{field2}, etc. but that's a little
cumbersome code-wise.
good luck
