I have a HolderPage.php and I create children page for HolderPage.php(ProjectPage.php)
When i show on template i write:
<% control Children %>
<h2>$Title</h2>

<% end_control %>

And i create ImageObject.php:
static $has_one=array('ProjectPage'=>'ProjectPage');
ProjectPage.php:static $has_many=array('ImageObjects'=>'ImageObject');
I show imageobject.php on template
<% control Children %>
<h2>$Title</h2>
<% control ImageObjects %>
$Photo
<% end_control %>
<% end_control %>
