Remote Service Method Call (RSMC) Methods

Hi everybody

 
I want to write a method to run in the server to generate, in batch, a set of entities from a "given base entity" as Pattern.
Basically i Have a given entity an through a cycle i create a set o new entities changing the key field.

From the client side I invoke the server method passing the “pattern entity”, de first number, last number and de Step.

the server creates new entities, adds them to the entimanager and calls the Savechanges method.

It Works well(the new entities are created in my sql server database), but , I

don’t know why the server method is called twice!!!
The SilverLight only calls it once!!!

Any tips would be apreciated

Thanks in advance

//--. Silver light  Side

private void DoConfirmCommand(object iView)

{

Alojamento _alojamento;

_alojamento = Alojamento.Create(0);

_mgr.AddEntity(_alojamento);

string typeName = "Alojamentos.Models.RemoteServiceMethods, AlojamentosWeb";

string methodName = "GenerateAlojamentos";

Guid myInvokeGuid = System.Guid.NewGuid();

DoAsyncAction(() => { _mgr.InvokeServerMethodAsync(typeName, methodName, GotData, myInvokeGuid, _alojamento, InicialRecord, FinalRecord, Step); });

}

protected void DoAsyncAction(Action a)

{

a();

}

void GotData(InvokeServerMethodOperation e)

{

if (!e.Cancelled)

{

bool gerou = (bool)e.Result;

}

}
