Hello dilbert4life,

We cannot reproduce this issue. Please make sure that you have file app/code/core/Mage/Adminhtml/Block/Permissions/Tab/Rolesedit.php

I'm also getting this problem and I also have the mentioned file.]]> #7 / Comment by akirsch

It is because of the "Tax Zones & Rates"

Warning: Mage_Admin_Model_Roles::_buildResourcesArray() [function.Mage-Admin-Model-Roles--buildResourcesArray]: unterminated entity reference Rates in app\code\core\Mage\Admin\Model\Roles.php on line 91]]> #8 / Comment by pting

I have the same error message, but 100% repro at a slightly different point.

1. Go to System > Permissions > Roles.
2. Click on the "Add New Role" button.
3. [Notice] The page renders incomplete with the error "Fatal error: Call to a member function toHtml() on a non-object in app/code/core/Mage/Adminhtml/Block/Permissions/Editroles.php on line 52".

I dug into the code and it boils down to this line "$this->getLayout()->createBlock('adminhtml/permissions_tab_rolesedit')->toHtml()" which is generating the issue. Since this is the first time I've ever looked at the code base, I'll investigate some more.]]> #9 / Comment by aSk

$this->addTab('account', array(
'label' => Mage::helper('adminhtml')->__('Role Resources'),
'title' => Mage::helper('adminhtml')->__('Role Resources'),
'content' => $this->getLayout()->createBlock('adminhtml/permissions_tab_rolesedit')->toHtml(),
));

generate the failure error, so to continu using the roles panel i turn this line into comment :

$this->addTab('account', array(
'label' => Mage::helper('adminhtml')->__('Role Resources'),
'title' => Mage::helper('adminhtml')->__('Role Resources'),
//'content' => $this->getLayout()->createBlock('adminhtml/permissions_tab_rolesedit')->toHtml(),
));
So the module work but the ressources roles content affectation is not displayed ^^.

What this error is realy ? Call to a member function toHtml() on a non-object]]> #10 / Comment by Alexandre Kraft

Reporting what Magento Team said 6 days ago on issue #4744:

This issue is a duplicate of #9872
#9872 is resolved and fixes are to be available in the next bugfix release (1.2.1).

@aSk: This error means, following PHP's logic, that $this->getLayout()->createBlock('adminhtml/permissions_tab_rolesedit') doesn't represent a valid object at the time the toHtml() method is called on it.]]> #11 / Comment by Magento Team
