    Do you have model.rezidentOtherCountry and model.rezidentOtherCountry.country exactly initialized? - Suvitruf ♦

In the class you need to add, for example, a constructor in the cat. initialize the collection

 public class rezidentOtherCountry { public bool? isRezidentOtherCountry { get; set; } public List<otherCountryObj> country; public rezidentOtherCountry() { country = new List<otherCountryObj>(); } }
