I have the following structure:

|-HolderPage
|---Page 1
|---Page 2

where Page 1 & 2 are children of the HolderPage. In my case, my Pages have a "has_many" relation to ImageResources (Images with Title and Caption). Now I'd like to automatically generate a list of the children within my HolderPage (that works really well) and add one (the first) of the ImageResources as a thumbnail to the list-entries on my HolderPage. I tried

function getOneHiglightImage() {
   return $this->HighlightImages("", "SortOrder ASC", null, 1);
}

within Page.php. For the template of the HolderPage I'm using:

function getChildren() {
      return DataObject::get("Page", "ParentID = $this->ID", "Title ASC", "", "" );
   }

and

<ul id="List">
         <% control getChildren %>
            <li>
                   <div class="Photo">
                    $getOneHiglightImage.HighlightAttachment                       
                   </div>
                   <div class="Title">
                      <% control Type %>
                         <a href="$Link" title="$Title">$Title</a>
                      <% end_control %>
                      <a href="$Link" title="$Title">"$Title"</a></div>
                  <div class="Summary">$Content.FirstParagraph</div>
               <div class="ReadOn clearfix">
                  <a href="$Link" title="$Title"><% _t('READMORE','Read more') %> ...</a>
               </div>
            </li>
         <% end_control %>
         </ul>

HighlightAttachment is where the Image is stored. But that doesn't work for me. Can someone help me?

Why can't you just use $HighlightImages.First?
