Question

I’m using Magento 1.5 and I’m getting a fatal error message when trying to access “Customers->Manage Customers” from Magento Backend.
error details :

Call to a member function setSaveParametersInSession() on a non-object in

/my_domain.com/public_html/app/code/core/Mage/Adminhtml/Block/Widget/Grid/Container.php
on line 59

and this is the peace of code inside Container.php where Magento gets stuck

protected function _prepareLayout()
{
    $this->setChild( 'grid',
        $this->getLayout()->createBlock( $this->_blockGroup.'/' . $this->_controller . '_grid',
        $this->_controller . '.grid')->setSaveParametersInSession(true) );
    return parent::_prepareLayout();
}

any help would be greatly appreciated
Thanks

Answer 1

It is not clear from the question, but …

I suppose you got this error while you are creating a new module with a adminhtml controller.

If so …

The error could be triggered by an erroneous _blockGroup declaration in the blocks that extend Mage_Adminhtml_Block_Widget_Grid_Container

Hope it helps
