Fatal error: Call to a member function setData() Observer.php on line 8

Question

I am new to Magento so any help would be appreciated. Whenever I click Catalog > Manage Products I get the error:

Fatal error: Call to a member function setData() on a non-object in /home/designac/public_html/app/code/local/Dac/MultiSku/Model/Observer.php on line 8

The code on line 8 in Observer.php is:

   $block->getColumn('sku')->setData('filter_condition_callback', array(

Any ideas?

Answer 1

change your code to

if($block->getColumn('sku')) {
  $block->getColumn('sku')->setData('filter_condition_callback', array('you_callback....'));
}
