I've noticed that summary fields doesn't seem to work when setting the title of a date field.

 public static $summary_fields = array( 
       'Member.FirstName' => 'First Name',
	   'Member.Surname' => 'Surname',
           'Member.Email' => 'Email',	
	   'StartDate' => 'First Night',
	   'EndDate' => 'Last Night', 	   
	   'Status'=>'Booking Status'  
   );

In the example above, the titles all show correctly for first name, last name, email, booking status, but the date fields just show 'Start Date' and ignore the title i've given them?

Is it a bug, or am I missing something? This is a datagrid field in a model admin area...

cheers

I'm having this same issue. I can set a custom label when calling a function in Summary fields (and in the above case it looks like it works with dot notation), but when using the local values the GridField shows the field name regardless of whether a custom label is given or not.

Stick Sticks - ended up doing the following:

// Tell the datagrid what fields to show in the table
   public static $summary_fields = array( 
	'Member.FirstName',
	'Member.Surname',
        'Member.Email',	
	'StartDate',	   
	'Status'
   );
   
   static $field_labels = array ( 
	'Member.FirstName' => 'First Name',
	'Member.Surname' => 'Surname',
	'Member.Email' => 'Email',	
	'StartDate' => 'First Night',		
	'Status'=>'Status'  
   );
