               etc -->
                    config.xml

You have a few errors in your rewrites. The following code should work. You do not need the full name after the <rewrite> think of it in terms of Mage::getModel('first/second_part') with the <rewrite> as the /

Answer 3

The problem was that the class to which I was overriding was calling a method in its parent class with same name.

return parent::_afterSave();  //calling parent class's _afterSave() 

So, when I overriden this class with my method _afterSave() then I was calling again the overriden class's method instead of the grand parent's class. That was just double overriding.

After realizing this I called the grand parent class with name:

return Mage_Abstract::_afterSave() //calling grand parent class's _afterSave()

As my understanding, I written a blog in which I explained the same issue.

We need to combin those two answers :

1. https://magento.stackexchange.com/a/11032/46286
2. https://magento.stackexchange.com/a/11029/46286

Try to add following to the first answer

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <EFk_Review>
            <active>true</active>

        </EFk_Review>

        <Efk_Adminhtml1>
            <active>true</active>
            <codePool>local</codePool>
        </Efk_Adminhtml1>
    </modules>
</config>
