CSLA .NET

This all looks OK.  This code should not cause edit level mismatch.  Are you calling BeginEdit immediately after loading the object before UI has a chance to interact with it?

Hi,

I would like to know how is the best way to model an use relationship between business objects in CSLA?

For example: I have a business object called Payment. This object has many properties like PaymentId, OrderId, BillingInfo, ShippingInfo.

BillingInfo and ShippingInfo are two businness objects storing all the information about the billing and the shipping.

I just want to avoid the "Edit level mismatch in AcceptChanges" exception when I reference this objects. I get this exception when I do this and try to update the payment object:

Payment.BillingInfo = Billing.GetBillingById(idBilling);
Payment.ShippingInfo = Shipping.GetShippingById(IdShipping);

So, How is the best way to model this scenario?

I appreciate your help!!

Ahh, I see…

I think this is because you are loading child objects through public properties, dirtying the parent object.  Load them through private members instead:

Payment._billingInfo = Billing.GetBillingById(idBilling);
Payment._shippingInfo = Shipping.GetShippingById(IdShipping);

Yes, the code is equal to Project Tracker Sample.

When I load the form, I bind the UI and call the BeginEdit method.

AddWinPart(new ProjectEdit(Project.GetProject(projectId)));

    public ProjectEdit(Project project)
    {
      InitializeComponent();

      // store object reference
      _project = project;

      // set up binding
      this.roleListBindingSource.DataSource = RoleList.GetList();

      BindUI();

      // check authorization
      ApplyAuthorizationRules();
    }
