Result of my test: I had included the line already >>>> require_once('DB/DataObject/FormBuilder.php'); But I did not call 'require_once' with the others, including all possible quickform elements are still __PHP_Incomplete_Class typed inside the formbuilder object : DB/DataObject/FormBuilder/QuickForm.php HTML/QuickForm/header.php HTML/QuickForm/hidden.php HTML/QuickForm/text.php Etc.... I require_once'd the /FormBuilder/QuickForm.php and that fixed Incomplete type error. Might there be a way to avoid requiring every single class used by quickform? To illustrate, here's a piece of HTML source generated when I call echo print_r($fb). If I require_once HTML/QuickForm/header.php this becomes typed correctly. Please advise, Justin.
