render FormBuilder Form

Hi! I have a $form object generated with: $builder=& DB_DataObject_FormBuilder::create($table_name); $form=& $builder->getForm(); I work with Smarty and if I assign the html code of the form object... $tpl->assign("MyForm",$form->toHtml()); the form appears correctly when I display the page $tpl->display('mytpl.tpl'); Now I have to customize the form and I know that the way to do this is with rendereing (quickform). Then I try : $renderer =& new HTML_QuickForm_Renderer_Array(true); // give some elements aditional style informations $renderer->setElementStyle(array( 'NOM_EMPRESA' => 'Verdana9NormalGrisFluix', 'CIF' => 'Verdana9NormalGrisFluix' )); $form->accept($renderer); // assign array with form data $tpl->assign('form', $renderer->toArray()); $tpl->display("smarty-dynamic.tpl"); Well, the result is that I only view '* Denotes required field'. What happens with the form? Why don't appear? If I put {$form} in the template I see 'array'. I'm sure that the array data of the form can be readed in tpl but I don't know why is not displayed. Anyone can help me? Thanks. Salutacions, Leo Márquez [ Enginyeria del software / Internet ] [ Calidae - www.calidae.com ] [ Himalaya Servers - www.himalayaservers.com ]
