Lazarus 1.5 ( Trunk Version ) with remobjects

Just found out if i just ignore the Error Message i get all Data from The Database.
It look like that it could have a Problem with my User Role Settings…

If a Table has no restrictions i do net get a Error.
But when i start the Application then i get the Error because i check for the User-rights.

procedure TDM.check_user_access_rights(Sender: TObject);
begin
  RemoteDataAdapter.FillWithDASql(tbl_AccessRights,'SELECT description FROM AccessRights');
  tbl_AccessRights.Open;
  db_rights := tbl_AccessRights.FieldByName('description').AsString;
end;
