Question

I got a fatal error with my component. Let's say the component name is com_shirts and this is my code
my code in administrator/component/com_shirts/controllers/code.php
<?php
defined('_JEXEC') or die;
jimport('joomla.application.component.controllerform');
class ShirtsControllerCode extends JControllerForm{
protected $view_list = 'codes';
}
my code in administrator/component/com_shirts/controllers/codes.php
<?php

return $form;
}

$items = parent::getItems();
foreach($items as &$item){
$item->url = 'index.php?option=com_shirts&task=code.edit&code_id='.$item->code_id;
$item->event_description = substr($item->code_desc, 0);
}
return $items;
}
function getListQuery(){
$query = parent::getListQuery();
$query->select('*');
$query->from('#__shirts_codes');
return $query;
}
}
my code in administrator/component/com_shirts/tables/code.php

class ShirtsViewCode extends JView{

function display($tmpl=NULL){

$this->form = $this->get('Form');
$this->toolbar();
parent::display($tmpl);
}
function toolbar(){
if($this->code->code_id){

}else{
JToolBarHelper::title(JText::_('COM_SHIRTS_ADD'));
}
JToolBarHelper::apply('code.apply', 'JTOOLBAR_APPLY');

JToolBarHelper::save2new('code.save', 'JTOOLBAR_SAVE_AND_NEW');
JToolBarHelper::divider();
JToolBarHelper::cancel('code.cancel');
}
}
and when I enter the component view, I get this error
"PHP Fatal error: Call to a member function getKeyName() on a non-object in /var/www/joomla/libraries/joomla/application/component/controllerform.php on line 393"
How do I fix this?
