I'm really puzzled by this. The following is code I use in about twenty 
places (with different dataviews, BindingManagerBases and field data of 
course) - it works in all but one case.

   dv_course := dataview.Create(ds.Tables['Kurs']);
   bm_course := Self.BindingContext[dv_course];


//dv_course.count shows the correct count
       dv_course.AllowNew := true;
       bm_course.AddNew;
       with dv_course.Item[bm_course.Position].Row do
       begin
         Item['fld_status'] := false;
         Item['fld_company'] := compnr2.ToString;
         Item['fld_tableid'] := 190;
         Item['fld_hours'] := '08:00:00';
       end;
       bm_course.EndCurrentEdit;
//dv_course.count shows one more than before, also correct

In the one case

     if ds.HasChanges then //ds = Dataset

returns false, in all other cases it returns true, as you would expect 
with a new record added and some fields set...

Has anybody heard of anything like this before? And more importantly 
knows a solution?

TIA.
