Using an attribute of a has_one relation as heading in Dataobjectmanager

Hello all,

Once again I find myself using the DataObjectManager to build the necessary user-friendliness into my site and in general I am enjoying the experience. However, as usual, I seem to have run into this one small issue that I cannot seem to get my head around.

Here's hoping one of you can help me out.

The project I am currently working is fairly straightforward: a few pages explaining the goal and activities of the association that is our customer; and a couple of pages listing members and such for logged-in users.

The page that is giving me trouble is a page listing the members of the direction. The DirectionPage has a has_many relation with the dataobject DirectionMember. DirectionMember in turn has a has_one relation to the DataObject Member.

In the CMS the DirectionPage contains a DataObjectManager that shows all linked DirectionMembers, defined like this:

$manager = new DataObjectManager(
	$this, // Controller
	'DirectionMembers', // Source name
	'DirectionMember', // Source class
	array(
		'Function' => 'Functie',
		'EmailAddress' => 'Emailadres'
	), // Headings 
	'getCMSFields_forPopup' // Detail fields (function name or FieldSet object)
	// Filter clause
	// Sort clause
	// Join clause
);

And this is the definition of DirectionMember:

class DirectionMember extends DataObject
{
	static $db = array (
		'EmailAddress' => 'Text',
		'Function' => 'Text'
    );
 
    static $has_one = array (
		'Member' => 'Member',
		'Parent' => 'DirectionPage'
    );
	
	public function getCMSFields_forPopup()
    {	
		$Group = DataObject::get_one("Group", "Title = 'WebsiteUsers'", "", "");
		$Members = $Group->Members(
					   $limit = '',
					   $offset = '',
					   '',
					   $sort = 'Member.Email',
					   $join = ''
					); 
		$dropdown = new DropdownField('MemberID','Lid',$Members->toDropdownMap('ID', 'Title', 'Selecteer lid'),$this->Member);
		
        return new FieldSet(
            new TextField('EmailAddress', 'Emailadres'),
			new TextField('Function', 'Functie'),
			$dropdown
        );
    }
}

Now, the above code works flawlessly... except that I would really like to show the DirectionMember's name as well as their function and email address. However, this name is stored inside the has_one field Member.
I had hoped that I could do something like this:

$manager = new DataObjectManager(
	$this, // Controller
	'DirectionMembers', // Source name
	'DirectionMember', // Source class
	array(
		'Member->Name' => 'Naam',
		'Function' => 'Functie',
		'EmailAddress' => 'Emailadres'
	), // Headings 
	'getCMSFields_forPopup' // Detail fields (function name or FieldSet object)
	// Filter clause
	// Sort clause
	

However, no such luck. Am I missing anything obvious, or is getting this name more involved?

Looking forward to your replies,
Bart M.

Thank you very much, that did the trick. I already suspected it had to be something simple. :)
