MVC Surface Controller & Umbraco Current Node

I am trying to write a childaction function in a surface controller that is called by a macro to render a PartialView.

I need this function in order to access my current page properties, then to customize the rendering of PartialView with.

I got this from Jorge Lusar's ubootstrap code, and it works fine in the HttpPost ActionResult function:

var renderModel = (UmbracoRenderModel)ControllerContext.RouteData.DataTokens["umbraco"];
var currentPage = renderModel.CurrentNode.AsDynamic();

The problem is that this error occurred while using the [ChildActionOnly] PartialViewResult function :

Unable to cast object of type 'System.String' to type 'Umbraco.Cms.Web.Model.UmbracoRenderModel'.
on 'var renderModel = (UmbracoRenderModel)ControllerContext.RouteData.DataTokens["umbraco"];'

The data in DataTokens ["umbraco"] seems to change between the two functions. If I am diplay DataTokens ["umbraco"]. ToString () for each of them, this is what happens:

In [ChildActionOnly], PartialViewResult Init () → "Surface" is displayed .

In [HttpPort] displayed publicly available HandleSubmit (model MyModel) → "Umbraco.Cms.Web.Model.UmbracoRenderModel" .

Thanks for any advice here.

I am using Umbraco 6.0.4 and it is as simple as:

var currentNode = Umbraco.TypedContent(UmbracoContext.PageId);

The same problems that I encountered getting Current Node Id in Surface Controller during Ajax Post, when we lose the hidden value uformpostroutevals.

Even if I try to post this value by taking it from the form displayed

@using (Html.BeginUmbracoForm("<ActionName>", "<Controller Name>Surface"))

null UmbracoContext, , .

HOTFIX. CurrentNodeId , Ajax:

javascript:

<script type="text/javascript">
  var Global = {
    //..List of another variables which can be usefull of frontend
    currentNodeId: @CurrentPage.Id
  };
</script>

Global.currentNodeId data:

var sendData = {
    currentNodeId: Global.currentNodeId,
    // another params 
};

$.ajax({
    method: 'POST',
    data: JSON.stringify(sendData),
    contentType: 'application/json; charset=utf-8',
    url: '/Umbraco/Surface/<ControllerName>Surface/<ActionName>',
    dataType: 'json',
    cache: false
})
