Model Binding not working with mvc1

We have very large object called FoodFormViewModel. We go to add page like

FoodFormViewModel foodFormViewModel = new FoodFormViewModel();
return View("Edit", foodFormViewModel);

But when we come to post method like

[AcceptVerbs(HttpVerbs.Post)]
[ValidateInput(false)]
public ActionResult Edit(FoodFormViewModel objViewModel)
{
    SaveProcess(objViewModel);
    return View(objViewModel);
}

Our objViewModel properties are all blank. Our FoodFormViewModel definition is

#region Properties

public MealPlannerDataManager MPManager { get; set; }

public Food Food { get; set; }

public SelectList FoodGroupLevel1 { get; set; }
public SelectList FoodGroupLevel2 { get; set; }
public SelectList FoodGroupLevel3 { get; set; }
public SelectList FoodType { get; set; }
public SelectList Company { get; set; }
public SelectList Brand { get; set; }
public SelectList NutritionSource { get; set; }
public SelectList DataSource { get; set; }
public SelectList PlannerSource { get; set; }
public SelectList PublishMonth { get; set; }
public SelectList PublishDay { get; set; }
public SelectList PublishYear { get; set; }
public SelectList TagTypes { get; set; }

public List<CheckBoxInfo> MealTime { get; set; }
public List<CheckBoxInfo> Condition { get; set; }
public List<CheckBoxInfo> Allergens { get; set; }
public List<CheckBoxInfo> Occasions { get; set; }
public List<CheckBoxInfo> Others { get; set; }
public List<CheckBoxInfo> SpecialDiet { get; set; }

public List<CheckBoxInfo> Products { get; set; }
public List<CheckBoxInfo> AgeGroup { get; set; }

public FoodNutritionInfo NutrInfo { get; set; }
public FoodNutritionInfo AltNutrInfo { get; set; }

Tag dummyTag = new Tag();
TagType dummyTagType = new TagType();
#endregion Properties

WE couldn't figure out the issue. Any help is highly appreciated. We are using MVC1 with VS 2008

My view contains 3-4 partial views, i am posting one of the partial view here

Personally, I think it is very odd to have properties of type SelectList and List<CheckBoxInfo> in your view model class. Most viewmodels should contain properties of very basic types, like string and int. The way you have, makes it very hard to debug & identify your problems but I would go and say that most likely the default model binder doesn't know how to bind values from HTML controls to your viewmodel props.

I would advise looking into building a custom modelbinder or rewriting the view model class. Or rewriting the app as a whole (but I guess that's not an option).
