When I have this form:

        $form = new Zend_Form();
        $form->setName('upload_form');
        $form->setMethod(Zend_Form::METHOD_POST);
        $form->setEnctype('multipart/form-data');

        $element = new Zend_Form_Element_File('upload_file');
        $element->setLabel('upload_file:')->setRequired(true)
            ->setDestination('C:\Temp')
            ->addFilter(new Zend_Filter_File_Rename('XXX', 'XXX'))
            ;
        $form->addElement($element);

        $element2 = new Zend_Form_Element_File('upload_file2');
        $element2->setLabel('upload_file2:')
            ->setDestination('C:\Temp')
            ->addFilter(new Zend_Filter_File_Rename('XXX', 'XXX'))
            ;
        $form->addElement($element2);
        
        $form->addElement(new Zend_Form_Element_Submit(array(
            'name' => 'Upload',
        )));

        $this->view->form = $form;
        
        if ($this->getRequest()->isPost()) {
            if (!$form->isValid($_POST)) {
                echo "Error";
            }
        }

And I submit it without choosing files, it should show the error message "The file 'upload_file' was not uploaded", but it shows "The file 'upload_file2' was not uploaded" by the first element.
