MVC unobtrusive validation only being applied to one nested model - asp.net-mvc-3

Question

I have a form made up of nested models as below:
foreach (var item in Model)
{
<h3>
#item.StageDescription
</h3>
<div class="well">
<table id="Item#(item.ID)" class="WizardOption">
<thead>
<tr>
<some headings here />
</tr>
</thead>
<tbody>
#Html.EditorFor(m => item.WizardOptions,"","WizardOptions",null)
</tbody>
</table>
</div>
}
The WizardOption class has a required field call Display Value:
public class WizardOptionMetaData {
[Required]
public string DisplayValue { get; set; }
}
This works fine for the first table, if I leave a DisplayValue field blank I get the error: "The DisplayValue field is required." and the following markup is rendered:
<input class="description-box" data-val="true" data-val-required="The DisplayValue field is required." id="WizardOptions_0__DisplayValue" name="WizardOptions[0].DisplayValue" type="text" value="">
But any tables after the first one don't get the validation rendered properly:
<input class="description-box" id="WizardOptions_1__DisplayValue" name="WizardOptions[1].DisplayValue" type="text" value="">
Where am I going wrong?

Found the answer on a question I didn't find until after I posted the question:
ASP.NET MVC 3: Generate unobtrusive validation when BeginForm is on the layout
#{
var originalContext = ViewContext.FormContext;
ViewContext.FormContext = new FormContext();
}
<!-- This will generate proper HTML5 data-* validation attributes -->
#Html.TextBoxFor(x => x.Prop1)
#Html.ValidationMessageFor(x => x.Prop1)
#Html.TextBoxFor(x => x.Prop2)
#Html.ValidationMessageFor(x => x.Prop2)
#{
ViewContext.FormContext = originalContext;
}
