Flash builder + Zend amf | Insertion function not working when called second time

Question

I'm using standart createOrders function which is autogenerated by Flash Builder 4.6. It works brilliantly when used once. Here is code:
protected function okButton_clickHandler():void
                var orders2:Orders = new Orders();
                //setting values
                createOrdersResult.token = ordersService.createOrders(orders2);
                ordersService.commit();
When same button is clicked second time and consequently okButton_clickHandler launched, data is not inserted to database. I added result handler with trace("saved"); and what I saw was that "saved" was written on first click, but not second.
Also I used Charles to see whether request is being sent second time. And no it is not.
Just tried to generate auto generate form. Only had to add commit(); because else request is not sent. And here is save problem — request is sent only on first button click.
So all in all problem is in fact that ordersService.createOrders(orders2); works only once. Because if i try
createOrdersResult.token = ordersService.createOrders(orders2);
                ordersService.commit();
                createOrdersResult.token = ordersService.createOrders(orders2);
                ordersService.commit();
OR
            createOrdersResult.token = ordersService.createOrders(orders2);
            createOrdersResult.token = ordersService.createOrders(orders2);
            ordersService.commit();
there is only one row added to database. Any ideas?

Think you can find the problem in your php / whatever -backend. Generated code does'nt much know about autoincrement table ids.
So for the example tabel orders:
orderID int(10) auto_increment
orderName varchar(255)
...generated php for createOrders looks like:
$stmt = mysqli_prepare($this->connection, "INSERT INTO $this->tablename (orderID, orderName) VALUES (?, ?)");
mysqli_stmt_bind_param($stmt, 'is', $item->orderID, $item->orderName);
So if you dont give the right orderID, the second insert will fail.
Delete the autoincrement parts and code will work:
$stmt = mysqli_prepare($this->connection, "INSERT INTO $this->tablename (orderID, orderName) VALUES (?, ?)");
mysqli_stmt_bind_param($stmt, 'is', $item->orderID, $item->orderName);
