set_value() after upgrade to 2.0 ?

Having a problem with set_value usage after upgrading to 2.0.

On initial page load, no form has been submitted, but form validation runs and == FALSE.

In view:

Code:

<?php

// var_dump of $user->first_name confirms 'Steve'

$u_first_name = array(
    'name'  => 'first_name',
    'id'    => 'first_name',
    'value' => set_value('first_name', $user->first_name),
    'size'  => 24,
);

// var_dump of $u_first_name['value'] == string(0)""

Did something change since I upgraded and set_value should be used differently?

Turns out that a previous developer had done some stupid stuff in a class extension that was causing the problem! What a waste of time
