Error while adding Attribute in Magento 1.4.2

I have started working on a fresh Magento 1.4.2 installation. When I try to add a new attribute I get 开发者_运维技巧the following error:

Fatal error: Call to a member function setIsPopup() on a non-object in /var/www/projects/magento/app/code/core/Mage/Adminhtml/controllers/Catalog/Product/AttributeController.php on line 117

I tried searching in google and found a solution here: http://www.magentocommerce.com/boards/viewthread/214159/

But that resolves add issue but it causes problem in Modifying a attribute.

I like to know if any better solution is available to this issue.

Thanks

Please try reinstalling the package "Mage_All_Latest" with the Magento Connect Manager and make sure, you have set the folder-permissions right. Ensure that the file magento/var/.htaccess, the directories magento/app/etc, magento/var, and all the directories under magento/media are writable by the web server.

It sounds like there was a problem while your install, so a reinstall of the latest packages maybe solves your problem.
