ASP.NET MVC3 RenderPage & Html.BeginForm

I have a problem with RenderPage along with Html.BeginForm (I don't know what I'm doing wrong).

Suppose you have a simple _Test.cshtml, for example:

@{
    <span>Test Text</span>
}

Then suppose you have a simple page like this one (which uses _Test.cshtml):

 @{
    Layout = null;
    var b = new int[] { 0, 1, 2, 3, 4 };
}

@{
    <html>
        <body>
            @* @RenderPage("~/Views/Shared/_Test.cshtml") *@
            <div>
                @foreach (int i in b)
                {
                    <div>
                    @using (Html.BeginForm("Action", "Controller", new { id = i }, FormMethod.Post, new { id = "frm_"+ i.ToString() })) 
                    {
                        <span>Label&nbsp;&nbsp;</span>
                        <input type="submit" id="@i.ToString()" value="@i.ToString()" />
                    }
                    </div>
                }
            </div>
        </body> 
    </html>   
}

If you comment out the call to the RenderPage helper, you will correctly receive a series of forms with the corresponding submit button. If you uncomment the RenderPage helper, no tag will be created. Not sure what's going on, can someone help me?

Why are you using RenderPage? Html.Partialseems more native:

@{
    Layout = null;
    var b = new int[] { 0, 1, 2, 3, 4 };
}
<html>
    <body>
        @Html.Partial("~/Views/Shared/_Test.cshtml")
        <div>
            @foreach (int i in b)
            {
                <div>
                @using (Html.BeginForm("Action", "Controller", new { id = i }, FormMethod.Post, new { id = "frm_"+ i.ToString() })) 
                {
                    <span>Label&nbsp;&nbsp;</span>
                    <input type="submit" id="@i.ToString()" value="@i.ToString()" />
                }
                </div>
            }
        </div>
    </body> 
</html>

( @{}, HTML):

<span>Test Text</span>

Try changing your _Test.cshtml to

<span>Test Text</span>

And this is probably a matter of taste, but I prefer Html.Partialto RenderPage.
