event observer inventory change configuration

Question

I tried to observe a quantity change event but I messed up with the config file a bit

config.xml:

    <events>
        <cataloginventory_stock_item_save_after >
            <observers>
                <unreal_bisn>
                    <class>unreal_bisn/observer</class>
                    <method>productBackInStock</method>
                </unreal_bisn>
            </observers>
        </cataloginventory_stock_item_save_after >
    </events>

Model/Observer.php

<?php

class Unreal_Bisn_Model_Observer
{

    public function productBackInStock()
    {
        die("Worked");
    }

}

When I change the qty of a product I see a warning that shows me I did a wrong configuration of namespaces somehow

Warning: include(Mage\Unreal\Bisn\Model\Observer.php): 

It should be

Unreal\Bisn\Model\Observer.php

Please let me know what to adjust.

thanks

Answer 1

Have you set the model?

<global>
     <models>
          <unreal_bisn><class>Unreal_Bisn_Model</class></unreal_bisn>
     </models>
</global>

Also, I can't remember if you'll break/confuse things using <unreal_bisn> inside <observer>, I'd use <unreal_bisn_observer> for that.
