I want to show product grid serialization in admin in my collections module. But I am getting error of

Fatal error: Call to a member function setCollectionsProducts() on a non-object

by printing $this->getLayout()->getBlock object I am getting Boolean false value. What is error in my below code.

CollectionsController.php

  • you donot need to call getBlock('collections.edit.tab.product') just call getBlock() which will read layout from xml

  • Can you add your etc/config.xml Nov 17 '14 at 22:51
  • module etc/config.xml already added here. if you want any other file please specify. Nov 18 '14 at 6:47
  • @ Magento warrior , Do you find the solution for above issue, I also conflicting with the same issue, please give your review .

Here getBlock('collections.edit.tab.product') returns null and that is why setCollectionsProducts() is not working. From your layout udpate xml file, collections.edit.tab.product block stands for the block class Gdata_Collections_Block_Adminhtml_Collections_Edit_Tab_Product. I can see that you defined that block file correctly.

So checkout the folder path for that file, it should be app/code/<codePool>/Gdata/Collections/Block/Adminhtml/Collections/Edit/Tab/Product.php.

Also make sure, your layout update xml file resides in admin theme section. That means it's location should be at app\design\adminhtml\default\default\layout\gdata_collections.xml

Also look for any log errors for more details.

clear the cache and try again.

In Magento 2 check the name of $this->_controller in your block will be same with $this->_view->getLayout()->getBlock( section in your controller.

Also, please note that adminhtml_customReport_orders and adminhtml_customreport_orders will be different and you should always consider the block folder name which is after adminhtml folder.
