QFC Action_Display - oldPage check

Hi, In Action/Display.php there's the following line bit of code:

       $pageName = $page->getAttribute('id');
       // If the original action was 'display' and we have values in container then we load them
       // BTW, if the page was invalid, we should later call validate() to get the errors
       list(, $oldName) = $page->controller->getActionName();
       if ('display' == $oldName) {
           // If the controller is "modal" we should not allow direct access to a page
           // unless all previous pages are valid (see also bug #2323)
           if ($page->controller->isModal() && !$page->controller->isValid($page->getAttribute('id'))) {
               $target =& $page->controller->getPage($page->controller->findInvalid());
               $target->handle('jump');
           }
           $data =& $page->controller->container();
           if (!empty($data['values'][$pageName])) {
               $page->loadValues($data['values'][$pageName]);
               $validate = false === $data['valid'][$pageName];
           }
       }

Why should we *only* load the container values if the original action was 'display' ? In some cases this extra IF block prevents me from doing what I want to do. An example: I have a multipage form wizard. When something specfic goes wrong during the the final form processing I would like to display a particular page (not using Jump!). I can do this using $page->handle('display'), but then all the form data has disappeared because of this IF block. I hope this makes sense. Any chance of getting rid of this IF block, or will this result on unwanted behaviour? TIA Jeroen
