Unobtrusive validation editorfor - asp.net-mvc-3

Question

I've got a partial View, loaded from an Action, so the parent view contains:
#Html.Action("TourSearch")
The TourSearch View uses a editor as such:
#Html.EditorFor(model => model.ImpersonatedAgentModel, "ImpersonatedAgentView")
where ImpersonatedAgentModel is as such:
[Serializable]
public class ImpersonatedAgentModel
{
[Required(ErrorMessage = "Please provide a User ref")]
public string AgentImpersonatedUserName { get; set; }
[Required(ErrorMessage="Please provide a ABTA/AgencyCode")]
public string AgentImpersonatedBranchCode { get; set; }
[Required(ErrorMessage = "Please provide a User ref")]
public int? AgentImpersonatedBranchID { get; set; }
}
My editor is pretty straight forward:
#model Travel2.WebUI.Models.ImpersonatedAgentModel
<ul id="agencyDetails">
<li>
<label for="AgentImpersonatedBranchCode">ABTA/Agency Code: *</label>
#Html.TextBoxFor(model => model.AgentImpersonatedBranchCode, new {ID="txtBranchCode" })
#Html.ValidationMessageFor(model => model.AgentImpersonatedBranchCode, "*")
<input id="txtBranchId", type="hidden" value="#Model.AgentImpersonatedBranchID" />
<input id="txtUserName", type="hidden" value="#Model.AgentImpersonatedUserName" />
<input id="hidCurrentController" type="hidden" value='#ViewContext.Controller.ValueProvider.GetValue("controller").RawValue' />
</li>
<li>
<label for="AgentImpersonatedUserName">User ref: *</label>
<select id="ddlUser" disabled="disabled" ></select>
<input type="hidden" id="txtUserID" />
#Html.HiddenFor(model => model.AgentImpersonatedUserName, new {ID="AgentImpersonatedUserName" })
#Html.HiddenFor(model => model.AgentImpersonatedBranchID, new {ID="AgentImpersonatedBranchID"})
#Html.ValidationMessageFor(model => model.AgentImpersonatedUserName, "*")
</li>
</ul>
Now in Chrome, all works fine. But when I fill in the form in IE but not the data in the Editor, it passes validation incorrectly!
If I examine the markup, using IEs poor excuse for Firebug, I can see the validation attributes,
<input name="ImpersonatedAgentModel.AgentImpersonatedBranchCode" id="txtBranchCode" type="text" data-val="true" data-val-required="Please provide a ABTA/AgencyCode" jQuery172048066185567747205="94"/>
so why is IE ignoring them!! Stupid IE

Found the answer here:

We were referencing Jquery validation too and this seems to be causing this error
