Question

I have a form I am trying to send in a GetJSON call. When I get to the Controller the model that si tied to the view is a null vlaue. I have had issues before dealign with returning data when I woudl get an empy object but never a null value. Below is the code I am using to send the form

  var cqvdata = $("form").serialize();

  $.getJSON('@Url.Action("GetEmailByAdvanced", "CustomerEmails")', { cqv: cqvdata }, function (contacts) {
       var emails = "";
       $.each(contacts, function (index, contact) {
           $('#BCCText').tagit('createTag', contact.Email)
       });

       return false;
   });

Below is what I have on the controller side

 public JsonResult GetEmailByAdvanced(MassEmailViewModel cqv)
 {


 }    

Here is what I get for results if I turn my argument into a string

"EmailFromAddressID=1&ToAddresses=&CCAddresses=bclairmont%40harr.com&BCCAddresses=adunn%40harr.com&Subject=&Body="

Below is the MassEmailViewModelClass and all sub classes

public class MassEmailViewModel
{
    public MassEmailViewModel()
    {
        ComplexQuery = new CustomerQueryViewModel();
    }

    public int EmailFromAddressID { get; set; }

    public CustomerQueryViewModel ComplexQuery { get; set; }

    public string ToAddresses { get; set; }
    public string CCAddresses { get; set; }
    public string BCCAddresses { get; set; }
    public string Subject { get; set; }
    [AllowHtml]
    public string Body { get; set; }

}

 public class CustomerQueryViewModel
{
    public CustomerQueryViewModel()
    {
        Products = new List<CustomerProductQueryProduct>();
        Details = new List<CustomerQueryDetail>();
    }

    public Boolean IncludeOnAll { get; set; }
    public Boolean ExcludeOnAll { get; set; }

    public List<CustomerProductQueryProduct> Products { get; set; }
    public List<CustomerQueryDetail> Details { get; set; }
}

public class CustomerProductQueryProduct
{
    public CustomerProductQueryProduct()
    {
        ProductDetails = new List<CustomerProductQueryProductDetail>();
        ProductVersions = new List<ProductVersion>();
    }

    public ProductType ProductType { get; set; }
    public Boolean Exclude { get; set; }
    public Boolean Include { get; set; }
    public int VersiondID { get; set; }

    public List<CustomerProductQueryProductDetail> ProductDetails { get; set; }
    public List<ProductVersion> ProductVersions { get; set; }
}

public class CustomerProductQueryProductDetail
{
    public ProductTypeDetail ProductDetail { get; set; }
    public Boolean Exclude { get; set; }
    public Boolean Include { get; set; }
    public string Value { get; set; }
    public string Value2 { get; set; }
}

public class CustomerQueryDetail
{
    public string Description { get; set; }
    public string Type { get; set; }
    public Boolean Exclude { get; set; }
    public Boolean Include { get; set; }
    public string Value { get; set; }
    public string Value2 { get; set; }
}

The only thing not being returned is my ComplexQuery in the serialize because I am using a JQuery dialog so it takes those elements out of the form. I woudl think I woudl get a MassEmaikViewModel with all the vlaues but ComplexQuery and have a null for that but I just get a null as iff the argument never even got initialized.

Any ideas on what could be causing this?

One other thing and I don’t know if this will help give anyone any insight or not but I can post from the form and have the MassEmailViewModel as the argument in the post and it works fine filling out all the values except for ComplexQuery

I figured it out after a ton of trial and error. It seems like GetJSON can’t handle passing the data. What I did to correctly get information was to change to an AJAX get call. I will post the code below

 $.ajax({
                            url: '@Url.Action("GetEmailByAdvanced", "CustomerEmails")',
                            type: 'GET',
                            data: cqvdata,
                            success: function (data) {
                                //called when successful
                                var emails = "";
                                $.each(contacts, function (index, contact) {
                                    $('#BCCText').tagit('createTag', contact.Email)
                                });

                                return false;
                            },
                            error: function (e) {
                                //called when there is an error
                                //console.log(e.message);
                            }
                        });

I used the exact data I had in the GetJSON. In fact I commented out the GetJSON and just put this in below it and I got my model filled in on the controller side.
