I can't figure out how to display the "Resources Link" under there appropriate "Resource Link Category" any help?

Here's the code.

ResourceLinkCategory.php

class ResourceLinkCategory extends DataObject {
	static $db = array('Name' => 'Text');
	
	static $has_many = array('ResourceLinks' => 'ResourceLink');

	function getCMSFields_forPopup() {
		$fields = new FieldSet();

		$fields->push (new TextField('Name'));

		return $fields;
	}
}

ResourceLink.php

class ResourceLink extends DataObject {
	static $db = array(
		'URL' => 'Text',
		'Description' => 'Text'
	);
	
	static $has_one = array(
		'ResourceLinkPage' => 'ResourceLinkPage',
		'MyResourceLinkCategory' => 'ResourceLinkCategory'
	);

	function getCMSFields_forPopup() {
		$fields = new FieldSet();

		$fields->push (new TextField('URL'));
		$fields->push (new TextareaField('Description'));
		$fields->push (new HasOneDataObjectManager(
		   $this,
		   'MyResourceLinkCategory',
		   'ResourceLinkCategory',
		   array('Name' => 'Name'),
		   'getCMSFields'
		));

		return $fields;
	}
}

ResourceLinkPage.php

class ResourceLinkPage extends Page {
	static $has_many = array(
		'ResourceLinks' => 'ResourceLink',
		'ResourceLinkCategories' => 'ResourceLinkCategory'
	);
	
	function getCMSFields() {
		$fields = parent::getCMSFields();
		
		$resourcelinks = new DataObjectManager(
			$this,
			'ResourceLinks',
			'ResourceLink',
			array(
				'URL' => 'URL',
				'Description' => 'Description'
			),
			'getCMSFields_forPopup'
		);
		$fields->addFieldToTab('Root.Content.ResourceLinks', $resourcelinks);
		
		return $fields;
	}
}

class ResourceLinkPage_Controller extends Page_Controller {
	function GetResourceLinkCategories() {
		return DataObject::get('ResourceLinkCategory', '', '', '', '');
	}
}

ResourceLinkPage.ss

<% control GetResourceLinkCategories %>
	<h2><span>$Name</span></h2>
        <-- Display Resources Link related to the Category here -->
<% end_control %>

<% control GetResourceLinkCategories %> 
	<h2><span>$Name</span></h2> 
	<% control ResourceLinks %>
	<!-- Resource link stuff here -->	
	<% end_control %>
<% end_control %>

There's always a method available with the same name as the relationship which acts as a getter for all related objects.
