Blazor 8.0 and CSLA 8.2 BusinessListBase [UpdateChild] fails on Update of new child object

[jhuerta3]

Hello All,

Can someone provide some help on this issue. I have a BusinessListBase with a list if editable root objects and when I try to insert the new child obhect (role) it fails. The stack trace is below. I was trying to follow ProjectTracker sample solution but it does not have the [UpdateChild] method so Im not sure if what I have is correct.

I read something about making async so I will try that in the meantime.

Thank you.

I would like to add that the [FetchChild] portion in the AspNetUserRoleEdit : BusinessBase is working okay. Its just the Update is not being called.

[jhuerta3]

I found the issue. Since I am using a Editable root object as a child object also I needed to add the insert method that did not take any parameters .

    [InsertChild]
    private void InsertChild([Inject] IAspNetUserRolesDal dal)
    {

        using (BypassPropertyChecks)
        {
            var item = new AspNetUserRoleEntity
            {
                RoleId = this.RoleId,
                UserId = this.UserId
            };
            var result = dal.Insert(item);
        }
    }

Also the name needs to be different from the editable root object insert. InsertChild
