Many thanks Jeff, I had messed up my WEB-INF\lib folder...problem solved.
But now that my transactions properly work, I have one more question.
In my library management application, I have a one-to-one relationship
between a Customer and his Id card. So when a customer comes to the
librarty and signs in, the employee manually inserts the customer's
data (surname, address and so on) in a form and I need the system to
automatically create the Id card when the employee submits the form
data. This is the code I'm using:
public static const millisecondsPerDay:int = 1000 * 60 * 60 * 24;
public var uuid:String;
private var token1:AsyncToken;
private var hibernatecustomer:DataService;
private var hibernatecard:DataService;
[Bindable]
private var clienteVo:Cliente;
[Bindable]
private var tesseraVo:Tessera;
private function addCliente():void {
clienteVo = new Cliente();
var date:Date = new Date();
var year:String = date.getUTCFullYear().toString();
var month:String = date.getUTCMonth().toString();
var day:String = date.getUTCDay().toString();
var hour:String = date.getUTCHours().toString();
var minutes:String = date.getUTCMinutes().toString();
var millisecs:String = date.getUTCMilliseconds().toString();
uuid = year + month + day + hour + minutes + millisecs;
clienteVo.idcliente = uuid;
clienteVo.cognome = newcognome.text;
clienteVo.nome = newnome.text;
clienteVo.datanascita = newdatanascita.text;
clienteVo.indirizzo = newindirizzo.text;
clienteVo.citta = newcitta.text;
clienteVo.provincia = newprovincia.text;
clienteVo.cap = newcap.text;
clienteVo.email = newemail.text;
clienteVo.telefono = newtelefono.text;
hibernatecustomer = new DataService("cliente.hibernate");
hibernatecustomer.addEventListener(ResultEvent.RESULT, addTessera);
hibernatecustomer.autoCommit = false;
var ir1:ItemReference = hibernatecustomer.createItem(clienteVo);
var token1:AsyncToken = AsyncToken(hibernatecustomer.commit());
token1.kind = "committed";
PopUpManager.removePopUp(this);
}
private function addTessera(event:ResultEvent):void {
if (event.token.kind == "committed") {
tesseraVo = new Tessera();
var currentDate:Date = new Date();
tesseraVo.idcliente = uuid;
tesseraVo.cliente = clienteVo;
tesseraVo.tprestiti = new ArrayCollection();
tesseraVo.datarilascio = currentDate;
tesseraVo.datascadenza = new Date(currentDate.getTime() + (3650
* millisecondsPerDay));
hibernatecard = new DataService("tessera.hibernate");
hibernatecard.autoCommit = false;
var ir2:ItemReference = hibernatecard.createItem(tesseraVo);
hibernatecard.commit();
}
}
Looks fine but I get this error:
Could not invoke sync method on data adapter for destination
'tessera.hibernate' due to the following error: class
org.hibernate.PropertyValueException:not-null property references a
null or transient value: fdspack.Tessera.datarilascio."
fdspack.Tessera.datarilascio is set by the code as:
var currentDate:Date = new Date();
tesseraVo.datarilascio = currentDate;
So why it tells me it is a "null or transient" value?
