I have a a partial view which contains other partial views. I am trying to the main partial view ( "MainPartialView" ) from an Ajax.ActionLink in a partial view contained by the main partial view ( "DetailsView" ). Everything appears to be called just fine and I can step through and it executes all of the code on the pages. However, after that is all done it throws this error in a popup box in visual studio:

htmlfile: Unknown runtime error

This error puts the break point in the MicrosoftAjax.js file, Line 5, Col 83,632, Ch 83632.

Any thoughts?

Index Page:

<script src="../../Scripts/MicrosoftAjax.js" type="text/javascript"></script>
<script src="../../Scripts/MicrosoftMvcAjax.js" type="text/javascript"></script>

<ul>
    <% foreach (DomainObject domainObject in Model) { %>
        <% Html.RenderPartial("MainPartialView", domainObject); %>
    <% } %>
</ul>

MainPartialView:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<DomainObject>" %>

<li>
    <div id="<%= Model.Id%>">
        <%= Ajax.ActionLink("Details",
             "PartialViewAction",
             "PartialViewController",
             new { id = Model.Id,  },
             new AjaxOptions { UpdateTargetId ="UpdateTargetId" })%>
             <% Html.RenderPartial("Details", Model); %>
             <div id="Details"></div>
    </div>
</li>

        <div>

                "DoAction",
                "XTrademark",
                new { id = Model.TrademarkId, id2 = actionStateLink.ActionStateLinkId },
                new AjaxOptions{ UpdateTargetId = Model.TrademarkId.ToString()} )%>
        </div>
    </div>
