destroy message not working

[jaimi]

I have defined the following code within my edatagrid:

 ,destroyMsg  : {
   norecord:{title:'Hinweis',
               msg:  'Es wurde kein Satz ausgewählt.'
             },
    confirm :{title:'Bestätigung',
               msg:  'Klicken Sie Ok, um die Firma zu löschen.'
             }
  }//destroyMsg

When I select a record and activate the remove-record-function it gives me the "confirm" message.
If no record is selected and I activate the remove-record-function nothing happens.
For my understanding the "norecord"-message should appear. What's wrong?
