title: ASP.NET MVC 2 - ViewData empty after POST
body: <p>I don't really know where to look for an error... the situation: I have an ASPX view which contains a form and a few input's, and when I click the submit button everything is POST'ed to one of my ASP.NET MVC actions.</p>
  
  <p>When I set a breakpoint there, it is hit correctly. When I use FireBug to see what is sent to the action, I correctly see data1=abc&amp;data2=something&amp;data3=1234. </p>
  
  <p>However, nothing is arriving in my action method. ViewData is empty, there is no ViewData["data1"] or anything else that would show that data arrived.</p>
  
  <p>How can this be? Where can I start looking for the error?</p>
