MVC3: How do I bind a model that contains a generic list of a certain class back to the controller? It always is null

Question

The Situation

Within the BuyerOtherInfoModel there is a generic list of BuyerPropertyInfoModels which is called LinkedProperties. When I load my view the editor template iterates through this generic list and works great. But when I postback I have issues with null values.

My Problem

My model binds to the view initially perfectly but when I postback the LinkedProperties generic list is always null. How do I make my editortemplate / jquery template match up correctly on postback? Sorry if this is hard to explain please ask for clarification.

Sorry guys this is my first question on stackoverflow and I have attempted to search for this problem already but I have no clue where to go from here. Let me know if you need any clarification on the issue. Thanks alot!

Answer 1

Add a constructor for BuyerListModel:

public class BuyerListModel {
    public int FirstItemOnPage { get; set; }
    // ...
    public PagedList<BuyListItem> ListItems { get; set; }

    public BuyerListModel() {
        // When it attempts to put the BuyListItems into the collection,
        // The parameter isn't initialized, so it's internally catching
        // a null reference exception.
        ListItems = new PagedList<BuyListItem>();
    }
}
