Submitting form results in InvalidDataOperation "Could not find property named Person on object of type MyProject.BlazorServer.Pages.Person." #245
Description
Example Code
Parent.razor
<ErrorBoundary Context="ErrorContext" @ref="errorBoundary"> <ChildContent> <EditForm EditContext="EditContext" OnValidSubmit="ValidSubmit" FormName="PersonForm"> <FluentValidationValidator /> <InputText @bind-Value="Person.FirstName" /> <ValidationMessage For="@(() => Person.FirstName)" /> <br /> <button style="background:green; padding:1em; color: white;" type="submit">Submit</button> </EditForm> </ChildContent> <ErrorContent> <div class="error"><span>An error occurred</span></div> </ErrorContent> </ErrorBoundary> @code{ private EditContext EditContext { get; set; } public Person Person { get; set; } private FluentValidationValidator validator; protected override async Task OnInitializedAsync() { if (Person == null) Person = new Person(); EditContext = new EditContext(Person); await base.OnInitializedAsync(); } }Person.cs
namespace MyProject.BlazorServer.Pages { public class Person { public string FirstName { get; set; } = string.Empty; public PersonAddress PersonAddress { get; set; } = new(); } public class PersonValidator : AbstractValidator<Person> { public PersonValidator() { RuleFor(p => p.FirstName).Cascade(CascadeMode.Stop).NotEmpty().WithName("FirstName"); } } }
Problem
ToFieldIdentifier is treating the class name as a property of its self. There is no Person.Person. I even tried to use .WithName() thinking that maybe it just needed to be manually set. This is sample code I'm using to debug a project I inherited which has totally jacked up validation. I assume that maybe there is some dependency that wasnt setup correct, but I can't find any reference to point to what would cause this exception and how to get past it.
