Hi again!
I'm trying to reload a TListConnector with the data provided by a web
service. The first time I load the data everything goes OK. The problem
is the second time I load the data in the same TListConnector. I've got
an error: "Column <columnname> does not belong to table <tablename>". I
tried to disable de TListConnector, assign TListConnector.DataObject:=
nil, ... it's impossible, I can get data anyway.
This is the code:

procedure GetData(ListConnector: TListConnector; const Table);
overload;
var
   ws : TWebService1;
   ds : DataSet;
begin
   try
     ds := DataSet.Create;
       ws := MakeWebService;
       ds := ws.GetData(Table);

     ListConnector.DataObject := ds.Tables[Table].DefaultView;
     ListConnector.Active:= true;

     ds := nil;
   except
     ListConnector.Active:= false;
     Raise;
   end;
end;

The program fails when I run "ListConnector.Active:= true" (the second
time, the first everything is OK).

HELP PLEASE!!!!
