ModelBinder returns null for one particular ViewModel
<p>I know, there's a lot of questions, tried the solutions, neither of them worked. Basically, I'm stuck...</p>

<pre><code>ViewModel:
public class CreateStrengthViewModel
{
    public string Strength { get; set; }
    public IEnumerable&lt;Categories.CategoryViewModel&gt; Categories { get; set; }
    public int Category { get; set; }
}

Controller:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create(
    [Bind(Include = "Strength,Category")]
    CreateStrengthViewModel strength)
    {
        using (StrengthServices service = new StrengthServices(new ImperialTobacco_Database()))
        {
            //service.CreateAndSave(strength);
            ...
        }
    }
}
</code></pre>

<p>The strength inside the controller method is null whatever I'm doing. The browser sends the data as you can see, but the ModelBinder just won't do a thing. Oh, and by the way: The very same code works for a different ViewModel with different Include fields. Yeah, I've tried to remove the Bind, or bind just one of the incoming variables nothing changes.</p>

<p>Funny thing is; this is working:</p>

<pre><code>public class CreateCompanyViewModel
{
    public string Name { get; set; }
    public string Color { get; set; }

    public IEnumerable&lt;MarketViewModel&gt; MarketsOfOperations { get; set; }
    public IEnumerable&lt;int&gt; SelectedOperations { get; set; }
}

    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Create([Bind(Include = "Name,Color,SelectedOperations")] CreateCompanyViewModel company)
    {
        using (CompanyServices service = new CompanyServices(new ImperialTobacco_Database()))
        {
            service.CreateAndSave(company);
            return RedirectToAction("Index", "Management");
        }
    }
</code></pre>

<p>I'll be honest, I have no idea what's going on and why the ModelBinder picks up nothing from the posted data, especially as a nearly identical one works perfectly.</p>

<p>P.S.: I tried changing the Property and Bind names yet again no luck.</p>
