Checkbox returns string "Null" after post

[Andrew Jang]

I have a checkbox as following in my View:

@using (Html.BeginForm())

{

    @Html.EJ().CheckBox("chkVerified").Text("Verified Document?")

    

}

And here is my Action to handle Submit (Post)

        [HttpPost]

        public ActionResult Index(FormCollection form)

        {

            ViewBag.Start = form["chkVerified"];

            return View();

        }

If the checkbox is unchecked and submitted, the value of form["chkVerified"] is "false"(string), which is good.

However, if the checkbox is checked and submitted, the value of form["chkVerified"] is "null"(string), which is weird because it used to return value "true"(string) in older versions.

This behavior is suddenly introduced to me ever since I installed the latest 15.4.0.17 and it's breaking all of my forms that use the checkbox.

If I rollback my project to the older version (e.g. 15.2.0.46), everything goes back to the way it was.

Am I missing some steps after installing the new version to make it work properly?
