Blazor 8.0 & CSLA 8.2 - Child object(s) is always IsNew = True Following ProjectTracker sample code

[jhuerta3]

Hello all,

Im working on BusinessBase User object with a child role list made up of a BusinessListBase and I notice that my child objects are all marked IsNew = true. So when I try to save the parent businessbase object the list executes the child insert and fails because some the roles for the user exist in the DB. Im not sure how to mark the child objects as IsNew = false for the initial roles that are in the list when the parent object is created. I also noticed that the BusinessListBase sample ProjectTracker does not have the UpdateChild method like they have before. I'm referencing the FieldManager.UpdateChildren(this) on my BusinessBase user object but no luck. Also, if I don't add the [UpdateChild] method to the BusinessListBase it fails. No update is called. I have a feeling im missing something. Can someone shed some light into my issue please.

Here is what I have. Sorry I'm not sure how to format this so it's easier to read.

I found the issue. I changed the AssignAsync name to Add so this was being called all the time and calling my Creator class and setting the object to new for each one. So I had to add base.Add(portal.FetchChild(item));

[Serializable]
public class AspNetUserRolesEditList : BusinessListBase<AspNetUserRolesEditList, AspNetUserRolesEdit>
{

    [FetchChild]
    private void Fetch(string UserID, [Inject] IAspNetUserRolesDal dal, [Inject] IChildDataPortal<AspNetUserRolesEdit> portal)
    {
        var data = dal.GetList(UserID);
        using (LoadListMode)
        {
            foreach (var item in data)
                base.Add(portal.FetchChild(item));
        }
    }


    //[UpdateChild]
    //private void Update([Inject] IAspNetUserRolesDal dal, [Inject] IDataPortal<AspNetUserRolesEdit> portal)
    //{
    //    using (LoadListMode)
    //    {
    //        foreach (var item in this)
    //        {
    //            AspNetUserRolesEdit child = item;
    //            portal.Update(item);
    //        }
    //    }
    //}
