I created a custom member type and added a while bunch of properties to it.

Using the Register Macro, I am unable to render the form woith all the properties. 

Stepping through the code shows that the Register model gets created fine (using the Alias) but the RegisterModel.MemberProperties collection has a count of 0.

Any suggestions?

My code:

@{    
    var registerModel = Members.CreateRegistrationModel("CareerMember");
    var success = TempData["FormSuccess"] != null;
}

@if (success) 
{ 
    @* This message will show if RedirectOnSucces is set to false (default) *@
    <p>Registration succeeeded.</p>
}
else
{
    using (Html.BeginUmbracoForm<UmbRegisterController>("HandleRegisterMember"))
    {
        <fieldset>
            <legend>Register Member</legend>

            @Html.ValidationSummary("registerModel", true)

            @Html.LabelFor(m => registerModel.Name)
            @Html.TextBoxFor(m => registerModel.Name)
            @Html.ValidationMessageFor(m => registerModel.Name)
            <br />

            @Html.LabelFor(m => registerModel.Email)
            @Html.TextBoxFor(m => registerModel.Email)
            @Html.ValidationMessageFor(m => registerModel.Email)
            <br />

            @Html.LabelFor(m => registerModel.Password)
            @Html.PasswordFor(m => registerModel.Password)
            @Html.ValidationMessageFor(m => registerModel.Password)
            <br />

            @if (registerModel.MemberProperties != null)
            {
                for (var i = 0; i < registerModel.MemberProperties.Count; i++)
                {
                    @Html.LabelFor(m => registerModel.MemberProperties[i].Value, registerModel.MemberProperties[i].Name)
                    @Html.EditorFor(m => registerModel.MemberProperties[i].Value)
                    @Html.HiddenFor(m => registerModel.MemberProperties[i].Alias)
                    <br />
                }
            }

            @Html.HiddenFor(m => registerModel.MemberTypeAlias)
            @Html.HiddenFor(m => registerModel.RedirectUrl)
            @Html.HiddenFor(m => registerModel.UsernameIsEmail)

            <button>Register</button>
        </fieldset>
    }
}
