THX.

My dirty work-a-round:

DateColumn<MitarbeiterDTO> leZugriff = new DateColumn<MitarbeiterDTO>() {
   @Override
    public Date getValue(MitarbeiterDTO object) {
         return (object.getLeZugriff());
     }
leZugriff.setDataView(maTable.getView()); // Problem in 2.6.0/1
....
maTable.addColumn("Le.Verwendung", leZugriff);

I could not find the difference to your working demo :/

I have the same problem. It's a little curious, as in one table I only get it work when I use above workaround. However, other tables work without the workaround, at least the addColumn call. But there I have a problem with sorting the table; getting a IndexOutOfBoundsException also in the AbstractDataView. I assume it's connected, because in 2.5 everything was working.
