Overide Magento Enterprise Core Observer Method
<p>Im Trying to over ride several methods located in the Enterprise_Catalog_Model_Observer class. In the core config this Observer is defined as </p>

<pre><code>        &lt;catalog_product_save_after&gt;
            &lt;observers&gt;
                &lt;catalog_product_save_custom_redirect&gt;
                    &lt;class&gt;enterprise_catalog/observer&lt;/class&gt;
                    &lt;method&gt;saveProductCustomRedirect&lt;/method&gt;
                &lt;/catalog_product_save_custom_redirect&gt;
            &lt;/observers&gt;
        &lt;/catalog_product_save_after&gt;
</code></pre>

<p>In my enxtension app/code/local/Extensioname/Redirects/etc/config.xml</p>

<pre><code>&lt;?xml version="1.0"?&gt;
&lt;config&gt;
    &lt;modules&gt;
        &lt;Extensioname_Redirects&gt;
            &lt;version&gt;0.1.0&lt;/version&gt;
        &lt;/Extensioname_Redirects&gt;
    &lt;/modules&gt;
    &lt;global&gt;
        &lt;models&gt;
            &lt;Extensioname_Redirects&gt;
                &lt;class&gt;Extensioname_Redirects_Model_Observer&lt;/class&gt;
            &lt;/Extensioname_Redirects&gt;
        &lt;/models&gt;
    &lt;/global&gt;

    &lt;frontend&gt;
        &lt;events&gt;
            &lt;catalog_product_save_after&gt;
                &lt;observers&gt;
                    &lt;extensioname_redirects&gt;
                        &lt;class&gt;Extensioname_Redirects_Model_Observer&lt;/class&gt;
                        &lt;method&gt;saveProductCustomRedirect&lt;/method&gt;
                    &lt;/extensioname_redirects&gt;
                 &lt;/observers&gt;
            &lt;/catalog_product_save_after&gt;
        &lt;/events&gt;
    &lt;/frontend&gt;
&lt;/config&gt;
</code></pre>

<p>in app/code/local/Extensioname/Redirects/Model/Observer.php</p>

<pre><code>class Extensioname_Redirects_Model_Observer extends Enterprise_Catalog_Model_Observer
{
    public function saveProductCustomRedirect(Varien_Event_Observer $observer)
    {
    ...
    }
}
</code></pre>

<p>But the core observer is still firing saveProductCustomRedirects and my extension is doing nothing. Please help</p>
