Quickform having strange behaviours

hello, i'm setting up a form with a simple text field and some advcheckboxes with value and description taken from a db: foreach ($descrizione as $chiave => $valore) { $nome[$counter] = 'tipologia_'.$counter; $prova =& HTML_QuickForm::createElement('advcheckbox',$nome[$counter],'',$valore,null,$chiave); $form->addElement($prova); $tmp = $prova->getChecked(); $test[$chiave] = $tmp; } $_POST['test'] = $test; maybe this is not the best code to use, but it works on my pc at home (win xp sp1, php 5.1.2, HTML_Quickform 3.5.2-cvs) while it not works at univerisity (linux, php 5.0.4, HTML_Quickform 3.5.2-cvs) this is the var_dump of $descrizione ON MY PC: array(4) { [2]=> string(3) "bla" [5]=> string(6) "cascon" [3]=> string(6) "fefefe" [1]=> string(4) "snow" } and this is the var_dump AT UNIVERSITY: string(6) "asbf c" i don't know what the problem is... i've got the same problem when using groups... looking into HTML/QuickForm/group.php i've found that the problem is in the onQuickFormEvent function which simply freeze when the form is submitted, or calls wrong addElement (in facts, it builds up a string instead of an array of objects) any suggestion? thanks, lorim.
