重写Magento块/第三方扩展的类

如何解决重写Magento块/第三方扩展的类

我正在尝试重写扩展的Block类，并引发了异常：

Mage_Core_Exception: Invalid block type:
  Hajdi_Brands_Block_Navigation
  in /Users/jure/Code/hajdi/app/Mage.PHP:598

这里提到了相同的重写。此重写包含与下面的链接上可接受的解决方案相同的代码，但不起作用。

知道我在做什么错吗？

app / etc / modules / Hajdi_Brands.xml

<config>
    <modules>
        <Hajdi_Brands>
            <active>true</active>
            <codePool>local</codePool>
            <depends>
                <Infortis_UltraMegamenu />
            </depends>
        </Hajdi_Brands>
    </modules>
</config>

app / code / local / Hajdi / Brands / Block / Navigation.PHP

<?xml version="1.0"?>
<config>
    <modules>
        <Hajdi_Brands>
            <version>1.0.0</version>
        </Hajdi_Brands>
    </modules>
    <frontend>
        <routers>

                </hajdi_brands>
            </updates>
        </layout>
    </frontend>
    <global>
        <blocks>

            </hajdi_brands>
        </blocks>
    </global>
</config>

app / code / local / Hajdi / Brands / Block / Navigation.PHP：

class Hajdi_Brands_Block_Navigation extends Infortis_UltraMegamenu_Block_Navigation

编辑： 这必须在一行中。

<navigation>
    Hajdi_Brands_Block_Navigation
</navigation>

<navigation>Hajdi_Brands_Block_Navigation</navigation>
