ASp.NET MVC: TryUpdateModel doesn't update all properties - asp.net-mvc

Question

I've got the following action:
public ActionResult Create()
{
var entity = new Employee();
TryUpdateModel(entity, new[] { "Person.Name", "Code", "CompanyID" });
if (ModelState.IsValid)
{
var result = Service.MergeEmployee(entity);
return RedirectToAction("List", new { success = true });
}
return View("Edit", new SupplierEmployeeModel() { Employee = entity });
}
What happens is that the property "Person.Name" doesn't get filled by the TryUpdateModel.
This is my form:
<fieldset>
<p>
<label for="Name"><%=Strings.NAME %></label>
<%= Html.TextBox("Person.Name", Model.Employee.Person.Name, new { Class = "text" })%>
<%= Html.ValidationMessage("Name", "*") %>
</p>
<p>
<label for="CompanyID"><%=Strings.SUPPLIER %></label>
<%= Html.DropDownList("CompanyID") %>
<%= Html.ValidationMessage("CompanyID", "*")%>
</p>
<p>
<label for="Code"><%=Strings.CODE %></label>
<%= Html.TextBox("Code", Model.Employee.Code)%>
<%= Html.ValidationMessage("Code", "*") %>
</p>
<p>
<%= Html.Hidden("ID", Model.Employee.ID)%>
</p>
<div id="tabs-DE-actions" class="ui-dialog-buttonpane ui-helper-clearfix" style="display: block;">
<button class="ui-state-default ui-corner-all" type="submit"><%=Strings.SAVE%></button>
</div>
</fieldset>
Any thoughts on why this is happening?
Thanks

Answer 1

Make sure the Person object is initialized in the Employee constructor; if it's null to begin with it is probably not updated properly.
public Employee()
{
Person = new Person();
}

Answer 2

Try this:
TryUpdateModel(entity,"Person", new[] { "Name", "Code", "CompanyID" });

In order to fill in Person.Name, the model binder has to create a new Person. Have you given the model binder enough info to do that? Alternately, try creating the Person yourself before binding.
