This question already has an answer here:
I have created custom module in magento. Its working good. But now my problem is, I want to add product grid to my product list tab.I have found the solution through this link.I have created new tab.But when i load that tab, its shows me an error like
Fatal error: Call to a member function setProdlist() on a non-object in /home/trendyc/public_html/app/code/community/Whole/Cate/controllers/Adminhtml/WhcatalogController.php on line 64
Mycontroller file's productsAction code here
$this->getLayout()->getBlock('products.grid') ->setProdlist($this->getRequest()->getPost('products_prodlist', null));
