Hallo, Im using Silverstripe 3.1.5

http://doc.silverstripe.org/framework/en/reference/templates
In the URL above is explained that you can loop thru items in reverse order but it does not seem to work.
I do not see what i'm doing wrong here.
This is my code.

<% loop GastenboekItems.Reverse %>
      $Content
      <div class="arrangement">
         <div class="bericht-info"><p>$Datum<p><h4>Naam: $Naam</h4></div>
         $Bericht
      </div>
<% end_loop %>

Works for me. But you need to define a sort first to reverse the sort.

<% loop $GastenboekItems.Sort(Naam).Reverse %>
   $Naam
<% end_loop %>

... which of course would be same as $GastenboekItems.Sort(Naam DESC)

Or:

public function GastenboekItems() {
   return GastenboekItems::get()->sort('Naam');
}

<% loop $GastenboekItems.Reverse %>
   $Naam
<% end_loop %>

Or you use $default_sort.

class GastenboekItems extends DataObject {
   private static $default_sort = 'Naam ASC';
}

<% loop $GastenboekItems.Reverse %>
   $Naam
<% end_loop %>

Thanks a lot, it works.

And the example of the function gives me a better understanding how to create your own functions.

Many thanks
