Post Array from Ext.Net store into ASP.NET MVC - json

Question

I know there are other questions on the forum regarding this but found ho helpful solution up to now.
I have a controller so defined:
[HttpPost]
public ActionResult Update(int id, IList<MyObject> data)
{
return Json(new { success = false, message = "saved!" });
}
A Json Array of MyObject is inside a JsonStore and sent up on the submitData() function call. I can see everything is sent up correctly, the "data" parameter is an array of MyObject, if I manually do JSON.Deserialize<IList<MyObject>>(data) I get exactly what I need, which means that data is a valid json string... in the Headers I can see the "application/json" content-type.
I am using the JsonValueProviderFactory already, but it does not help. From my understanding it seems that the value provider should easily map arrays into IList, so I am wondering if I am doing something wrong...
Thanks!
UPDATE
As noted in one comment I have a slightly different use scenario: I am actually posting this data through a Store.submitData() call... apparently, even though the headers are similar, the store submit does not work because it actually generates a string.
Does anyone have any knowledge on how to force the store to do something similar to JSON.stringify?

You haven't shown your client code but the following should work fine:
Ext.Ajax.request({
url: '#Url.Action("update", new { id = "123" })',
method: 'POST',
headers: { 'Content-Type': 'application/json' },
params: JSON.stringify({
data: [
{ foo: 'value 1' },
{ foo: 'value 2' },
{ foo: 'value 3' }
]
}),
success: function (response) {
alert(response.responseText);
}
});
It assumes that MyObject is defined like this:
public class MyObject
{
public string Foo { get; set; }
}
but of course it could be just any complex object.
