Dropdown ignores database entry

I know it is not only me having this problem, but no one can tell me how to fix this. I have a dropdownfield and want to save an id with it. After submit, the id is stored in the database and the dropdown shows the selected value. But after requesting the form from the sitetree again, the dropdown shows the first value, in my case "Please choose".

Example of my source (Location extends DataObject):

   public static $has_one = array(
      "MeetingPoint" => "Location"

   public function getCMSFields() {
    $fields = parent::getCMSFields();
    // create or find tabs
    $fields->findOrMakeTab( "Root.Content.Locations" );

$meetingPoint = new DropdownField( "MeetingPoint", "Meeting Point", DataObject::get( "Location" )->toDropDownMap( "ID", "Name", "Please choose" ) );
      $fields->addFieldToTab( "Root.Content.Locations", $meetingPoint );
    return $fields;

   function onBeforeWrite()
      $this->MeetingPointID = $this->MeetingPoint;

Is this an official bug?

You should name your dropdown field 'MeetingPointID' rather then 'MeetingPoint' and then get rid of your onBeforeWrite() call. Its confusing SS since when it loads the data it doesn't quite remember that MeetingPointID is to go into MeetingPoint. Well at least I'm pretty sure thats the solution.

Great! This fixed it! I can now use all my dropdowns and it selects stored values as given! Perfect! Thanks a lot!
