I'm with a ModelState validation issue that I can't find the solution. I have the following page load:

[BindProperty]

public ApplicationLanguage UpdatedLanguage { get; set; }

[BindProperty]

public IList<ApplicationTranslation> ApplicationTranslations { get; set; }

public async Task<IActionResult> OnGetAsync(Guid id)

{

    if (ModelState.IsValid)

    {

        {

            UpdatedLanguage = await _languageService.FindByIdAsync(HttpContext, id);

            ApplicationTranslations = await _translationService.GetAllTranslationsAsync(UpdatedLanguage);

        }

    }

    return Page();

}

This populates correctly the following page:

<h4>@Model.UpdatedLanguage.Name</h4>

<hr />

<div class="container">

    <div class="form-group">

        <input asp-for="UpdatedLanguage.Id" hidden="hidden" />

    </div>

    <form method="post">

        <div class="row">

            @for (int i = 0; i < Model.ApplicationTranslations.Count; i = i + 2)

            {

                <div class="col-sm-3">

                    <label> @Model.ApplicationTranslations[i].Tag</label>

                </div>

                <div class="col-sm-3">

                    <div class="form-group">

                        <input asp-for="ApplicationTranslations[i].Translation" class="form-control" />

                        <span asp-validation-for="ApplicationTranslations[i].Translation" class="text-danger"></span>

                    </div>

                </div>



                <div class="col-sm-3">

                    @if (i + 1 < Model.ApplicationTranslations.Count)

                    {

                        <label> @Model.ApplicationTranslations[i + 1].Tag</label>

                    }

                </div>

                <div class="col-sm-3">

                    @if (i + 1 < Model.ApplicationTranslations.Count)

                    {

                        <div class="form-group">

                            <input asp-for="ApplicationTranslations[i+1].Translation" class="form-control" />

                            <span asp-validation-for="ApplicationTranslations[i+1].Translation" class="text-danger"></span>

                        </div>

                    }

                </div>

            }

        </div>

        <div class="row">

            <button type="submit" class="btn btn-default">@WebTranslator.Translate(HttpContext, "Save")</button>

        </div>

    </form>

</div>

But when I save the form I have an invalid ModelState:

public async Task<IActionResult> OnPostAsync(ApplicationLanguage UpdatedLanguage, IList<ApplicationTranslation> ApplicationTranslations)

{

    if (!ModelState.IsValid)

    {

        return Page();

    }

 List<ApplicationTranslation> OriginalApplicationTranslations = (List<ApplicationTranslation>)(await _translationService.GetAllTranslationsAsync(UpdatedLanguage));

    foreach (ApplicationTranslation translation in ApplicationTranslations)

    {

        ApplicationTranslation originalTranslation = OriginalApplicationTranslations.Find(t => t.Tag == translation.Tag);

        IResult result = new ApplicationResult();

        if (result.Succeeded && originalTranslation.Translation != translation.Translation)

        {

            result = (await _translationService.UpdateAsync(HttpContext, translation));

        }

    }

return RedirectToPage("./Languages");

}

When debbugin, I found that on ModelState Values, the ApplicationLanguage.Id value is valid, but the ApplicationLanguage.Name and all ApplicationTranslations are invalid but I don't know why.
