Hi there,

Good to hear. I worked on the code... mine looks a bit different...but i checked it and it works:

<?php
class Termin extends DataObject {
static $db = array(
'FirstDate' => 'Date',
'DateRange' => 'Varchar',
'Description' => 'HTMLVarchar'
);

function getCMSFields() {
            
      $fields = new FieldList(
      $dateField = new DateField('FirstDate', 'FirstDate'),
      new HTMLEditorField('Description','Beschreibung'),
      new TextField('DateRange','Termin')
      );
    $dateField->setConfig('showcalendar', true);
    $dateField->setConfig('dateformat','dd-MM-yyyy');

    return $fields;
   }
}
