}

RecentProjectObject.php

static $has_one = array(
'ImageRecentObject' => 'Image',
'RecentProjectObject' => 'RecentProjectObject',
);

}

ProjectsAndServicesPage.ss

<% control RecentProjectObject %>
<li<% if Last %>class="last"<% end_if %>>

<h3>$TitleProject</h3>
<p class="welcome">$WelcomeProject</p>

<% end_control %>

ProjectsAndServicesPage.php
class ProjectsAndServicesPage_Controller extends Page_Controller {

function getRecentProjectImagesObjects($limit = 3) {
$url = $this->request->param('ID');
return DataObject::get("RecentProjectImagesObject", "RecentProjectObjectID='$url'", "ID Asc", "", $limit);
}

}

I write <% control getRecentProjectImagesObjects %>. This doesn't work. Please Help
