We'll try that out and let you know here about our succsess!

hi,
I had the same problem with my custom "Record-Page" (extends Page) and no access to my Methods that are defined in Record_Controller.

I saw this Entry: http://www.silverstripe.org/general-questions/show/262016

so I add the Contoller manually to the DataObject.

function getFilterRecords() {
	$recordSet = DataObject::get("Record", "`SiteTree`.`ParentID` = '".$this->ID."'$additionalFilter");
	
	if (!$recordSet || !$recordSet->exists()) return false;
		
	// add controller
	foreach ($recordSet as $record) {
		$record->controller = ModelAsController::controller_for($record);
	}
		
	return $recordSet;
}

In Template:

<% if FilterRecords %>
<% control FilterRecords %>
<h1>$Title</h1> <!--  access via http://doc.silverstripe.org/built-in-page-controls#titles_and_cms_defined_options -->

<p>$controller.MyControllerMethod</p><!-- access via the record_controller -->

<% end_control %>
<% end_if %>

I hope this could help too.
