Well, I'm working with tpl_form, and I did need to make a couple of 
changes and wrappers, but it is really a good tool once you have it 
set up properly.

The main issue is setting up defaults when you use it for update 
rather than new records.

This issue is related to your problem.

You can do one of two things:

1. Change the value of the global variable before you display the 
form. Maybe you even need to do that before you create the form. 
Certainly before get_values().

The form gets the values to display the second time around from 
whatever you submitted. However, it doesn't use HTTP_POST_VARS (or 
_POST), but the simple global variables. So changing the variable's 
value should do the trick.

2. Change the value of the variable in the ooh_forms element. This 
method is "unsupported" in that you are not supposed to know how 
ooh_forms actually work. However, I use it for the "update" 
situation. It is a good method even after you have used get_values.

Say your form is $f, and the field name is 'email' then

$f->form_data->elements['email']['ob']->value = '';
