MVC ActionMethod not finding passed in Value

I have a Create ActionMethod, something along the lines of:

[AcceptVerbs(HttpVerbs.Post)]
public ActionMethod Create(Journey journey)
{
  if (Request.IsAjaxRequest())
  {
    //Save values
    return Json(new { JourneyID = journey.JourneyID } );
  }
}

The Journey object that I pass in is from my LINQ2SQL datamodel. I call the above ActionMethod from my Javascript using the JQuery.Post fu开发者_C百科nction, like:

var journeyData = {
    CustomerID: $('#CustomerID').val(),
    JourneyID: $('#JourneyID').val(),
    EstimatedTravelTime: $('#EstimatedTravelTime').val(),
    RouteName: $('#RouteName').val(),
    .....
};

$.post('/Journey/Create',
  journeyData,
  function(jsonResult) {
    //deal with result
  },
  'json'
);

The issue that I am having is that in the ActionMethod Journey.RouteName is always returning as null but the JSON that I pass back has a value, I check this using

alert(JSON.stringify(journeyData));

and in the resultant JSON object RouteName has a value, e.g. 'Go to work'. Any ideas why this wouldn't be being set in the ActionMethod? All other values that I pass back are being set fine.

Just a try and error suggestion:

First thing i would try is to rename "RouteName" param with somethign different, as "RouteName" is also a property of some MVC-redirect methods..

Have you examined your request JSON object that's going to the server?
Have you tried adding quotes to your string property value?
Like this:

var journeyData = {
    CustomerID: $('#CustomerID').val(),
    JourneyID: $('#JourneyID').val(),
    EstimatedTravelTime: $('#EstimatedTravelTime').val(),
    RouteName: '"' + $('#RouteName').val() + '"',
    .....
};

There are a couple of things to consider. I'm guessing this is already in place, but your model must have a getter and setter on the RouteName property in order to be properly bound. Another thought is you might not be establishing the strong binding. This is usually done as part of the view's page declaration (e.g. Inherits="System.Web.Mvc.ViewPage") but I'm not sure this is happening prior to your post.
