I want to use RenderPartial twice in my view with different models associated. The problem is that some properties are present in both models (nickname, password). They have no prefix, so even the id's or names are equal in the output. Now, if I have model errors for nickname or password, both fields get highlighted.

Main View:

<div>
    <% Html.RenderPartial("Register", Model.RegisterModel); %>
</div>
<div>
    <% Html.RenderPartial("Login", Model.LoginModel); %>
</div>

Login PartialView:

<% using (Html.BeginForm("Login", "Member")) { %>
<fieldset>
    <legend>Login</legend>
    <p>
        <%= Html.LabelFor(x => x.Nickname) %>
        <%= Html.TextBoxFor(x => x.Nickname) %>
    </p>
    <p>
        <%= Html.LabelFor(x => x.Password) %>
        <%= Html.PasswordFor(x => x.Password) %>
    </p>    
    <input type="submit" value="Login" />
</fieldset>

<% } %>

Register PartialView:

<% using (Html.BeginForm("Register", "Member")) { %>
<fieldset>
    <legend>Register</legend>
    <p>
        <%= Html.LabelFor(x => x.Nickname) %>
        <%= Html.TextBoxFor(x => x.Nickname) %>
    </p>
    <p>
        <%= Html.LabelFor(x => x.Email) %>
        <%= Html.TextBoxFor(x => x.Email) %>
    </p>
    <p>
        <%= Html.LabelFor(x => x.Password) %>
        <%= Html.PasswordFor(x => x.Password) %>
    </p>
    <p>
        <%= Html.LabelFor(x => x.PasswordRepeat) %>
        <%= Html.PasswordFor(x => x.PasswordRepeat) %>
    </p>
    <input type="submit" value="Register" />
</fieldset>

<% } %>

How can I change this?
