覆盖Magento类(Adminhtml-View)

Question

我想扩展给定的类Mage_Adminhtml_Block_Sales_Order_Invoice_View，以添加更多的按钮。但这不是问题所在:我的自定义类不会加载。

我遗漏了什么？

app/etc/modules/Cb_Adminhtml.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Cb_Adminhtml>
            <active>true</active>
            <codePool>local</codePool>
        </Cb_Adminhtml>
    </modules>
</config>

app/code/local/Cb/Adminhtml/etc/config.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Cb_Adminhtml>
            <version>0.1</version>
        </Cb_Adminhtml>
    </modules>
    <global>
        <blocks>
         <adminhtml>
            <rewrite>
                <sales_order_invoice_view>Cb_Adminhtml_Block_Sales_Order_Invoice_View</sales_order_invoice_view>
            </rewrite>
        </adminhtml>
        </blocks>
     </global>
</config>

app/code/local/Cb/Adminhtml/Block/Sales/Order/Invoice/View.php

<?php

class Cb_Adminhtml_Block_Sales_Order_Invoice_View extends Mage_Adminhtml_Block_Sales_Order_Invoice_View
{
    public function __construct()
    {
        var_dump(get_class($this)); exit();
    }
}

您选择的模块名称可能会导致冲突。将其从Adminhtml更改为其他内容，然后再试一次。
