Calling an admin block from xml layout issue

Question

This is the content of my custom module, config.xml file:

<adminhtml>
 <layout>
 <updates>
 <mymodule>
 <file>homepage.xml</file>
 </mymodule>
 </updates>
 </layout>
 </adminhtml>

this is the content of the layout/homepage.xml file from

<?xml version="1.0"?>
<layout>
 <adminhtml_manage_index>
 <reference name="content">
 <block type="mynamespace_mymodule/adminhtml_banner" name="mynamespace_mymodule_banner" />
 </reference>
 </adminhtml_manage_index>
</layout>

This is the content of my controller Mynamespace/Mymodule/controllers/Adminhtml/ManageController.php

class Mynamespace_Mymodule_Adminhtml_ManageController extends Mage_Adminhtml_Controller_Action
{
 public function indexAction()
 { 
 $this->loadLayout();
 $this->_initAction()->renderLayout();
 } 
}

and the content of the Mynamespace/Mymodule/Block/Adminhtml/Banner.php

class Mynamespace_Mymodule_Block_Adminhtml_Banner extends Mage_Adminhtml_Block_Widget_Grid_Container
{
 public function __construct()
 {
 echo 1; exit();
//....
 }
}

My problem is that it doesn't access the block. I put an exit() there . But I cannot get there. Why ? What am I missing ? thx

• Abdul: Please replace Mynamespace/Mymodule/Block/AdminHtml/Banner.php to and the content of the Mynamespace/Mymodule/Block/Adminhtml/Banner.php
• Abdul: Mynamespace/Mymodule/controllers/AdminHtml/ManageController.php to Mynamespace/Mymodule/controllers/Adminhtml/ManageController.php
• Attila Naghi: @Abdul I don't understand. Can you give more details!
• Abdul: rename folder name "AdminHtml" => "Adminhtml"
• Attila Naghi: sorry my mistake, it is Adminhtml not AdminHTML, from the start, I updated my post

Answer 1

Rename folder name "AdminHtml" => "Adminhtml"

Please replace from

<?xml version="1.0"?>
<layout>
 <adminhtml_manage_index>
 <reference name="content">
 <block type="mynamespace_mymodule/adminhtml_banner" name="mynamespace_mymodule_banner" />
 </reference>
 </adminhtml_manage_index>
</layout>

To

<?xml version="1.0"?>
<layout>
 <mymodule_adminhtml_manage_index>
 <reference name="content">
 <block type="mynamespace_mymodule/adminhtml_banner" name="mynamespace_mymodule_banner" />
 </reference>
 </mymodule_adminhtml_manage_index>
</layout>
