Im about to create a selfmade image gallery. i created a datamodel named GalleryImage.
and added a "Title" to the static $db.

I created a GalleryPage page type and added

static $has_many = array("Images"=>"GalleryImage");

to it.
Then i ran /dev/build?flush=1
and altough ive added some GalleryImages to it and inserted

<% control Images %>
$Title <br>
<% end_control %>

inside my GalleryPage.ss file no Title of the Images shows.

edit:

GalleryPage.php : http://pastie.org/719094
GalleryPage.ss : http://pastie.org/719095
GalleryImage.php : http://pastie.org/719098
