accessing Controller.ViewData.Model is always null

[Sean Chambers]

I am trying to convert my spark views to use ViewData.Model instead of
the namevaluecollection so that I can use AutoMapper to map my dto's
to entities before it gets into my action method.

I can access the viewdata.model from the view, but upon posting back
the data, viewdata.model is null. here is some sample code:

in my view:
<viewdata Message="string" model="MyDto" />
${Model.Id} < -- displays MyDto.Id

In my filter, OnActionExecuting on the server I am trying to do:
var model = filterContext.Controller.ViewData.Model;

but ViewData.Model is null. This is during OnActionExecuted. Is there
a trick to get the ViewData.Model to grab the values from the posted
view?

thanks

ViewData is for passing data from the controller to the view, not for reading input in the controller/action layer.
