I have a custom module and I have a working grid to menage the module items in the admin.
My module file structore is : app\code\local\G4R\GroupSales\Block\Adminhtml\Groupsale\
I want to add an edit form so I can view and edit each item in the grid.
I followed this tutorial : http://www.magentocommerce.com/wiki/5_-_modules_and_development/0_-_module_development_in_magento/custom_module_with_custom_database_table#part_2_-_backend_administration
but when the edit page loads, instead of the tab content I get an error :
Fatal error: Call to a member function setData() on a non-object in C:\xampp\htdocs\mystore\app\code\core\Mage\Adminhtml\Block\Widget\Form\Container.php on line 129
This is my code :

Any ideas what is the cause for the error?
