FormBuilder

Hi Seems the formbuilder docs site is down at the moment. So Is it possible to do something like the below -

    function preGenerateForm(&$fb)
    {
    $el = HTML_QuickForm::createElement('hidden',
                                        array('creation_date', 'revision_date'));

    $this->fb_preDefElements['creation_date'] = $el;
    $this->fb_preDefElements['revision_date'] = $el;
    }

causes - Warning: Illegal offset type in isset or empty in D:\AWebEnvironment\PHP5.2.0\PEAR\HTML\QuickForm.php on line 610 Also I noticed that there was an inbuilt HTML area with formbuilder how do I activate this and also find info on the other elements extensions available - I suppose they are in the docs but dont know when that will be back. Cheers Ian
