Dialog.Update(table) does not work

Hello,

I made a simple sql database program.
On the form i inserted a SqlControls.Table object, which i linked to
a 'table:SqlDB.Table' Object.

If i do a test, the result of a sql select statment, has no effect to 
the SqlControl object on the form. But if i delete and insert the 
SqlControl on the form again, the SqlControl works.

Do i make something wrong, or is that a bug?

Here the source code:

MODULE Test;
IM****T Dialog, Views, TextModels, TextControllers, SqlDB, SqlControls;
	
VAR statement*: ARRAY 1024 OF CHAR;
     table*: SqlDB.Table;	(* anchor for database *)

PROCEDURE Execute*;
VAR res: INTEGER; db: SqlDB.Database;
     id, pwd, database, driver: ARRAY 32 OF CHAR;
BEGIN
   id := ""; password := "";
   database := "Test Database";
   driver := SqlOdbc3";
   IF table = NIL THEN
     SqlDB.debug:=TRUE;
SqlDB.OpenDatabase(driver,id,pwd,database,SqlDB.async,SqlDB.showErrors,db,res);
     table := db.NewTable();
   END;
   table.Exec(statement);
   Dialog.Update(table);			
END Execute;
	
BEGIN
END Test.

Yours sincerely
Helmut
