New customer account link not automatically highlighted

Question

I'm trying to figure out why Magento is not highlighting my new customer account link when I access the corresponding page. Here is my code :

<?xml version="1.0"?>
<layout version="0.1.0">
    <default>
          <reference name="content">
          </reference>
      </default>
    <customer_account translate="label">
        <reference name="customer_account_navigation">
            <action method="addLink"><name>Mes parrainages</name><path>mesparrainages/index/index/</path><label>Mes parrainages</label></action>
        </reference>
    </customer_account>
      <mesparrainagesrouter_index_index>
        <update handle="customer_account"/>
           <reference name="my.account.wrapper">
                <block type="parrainage/mesparrainagesblock" name="bloc_mesparrainages" as="bloc_mesparrainages" template="parrainage/mesparrainages.phtml" />
           </reference>
      </mesparrainagesrouter_index_index>
</layout>

I'm using CE 1.9, maybe they changed the way it works.. Somebody have an idea please ?

Answer 1

Your block definition is wrong here

<block type="modulename/blockname" name="block_name" template="template.phtml" />

As per your module configuration it should look like

<block type="parrainage/blockname" name="block_name" as="block_name" template="template.phtml" />

since parrainage is the alias for your module's block. But in order to ensure this block render its content, you may also need to look on this

1. You should have block defined in backend

Location : app/code/local/Motion4Ever/Parrainage/Block/Blockname.php

<?php
class Motion4Ever_Parrainage_Block_Blockname extends Mage_Core_Block_Template {

}

Without defining this block class, Magento would not understand which block that you are referencing in layout file

2. You need to ensure the parent block is defined before referencing the block.

In this case, this step won't be necessary. Since it is defined in customer.xml
