ASP.NET MVC ViewData (using indices) -

-

i had working solution using asp.net mvc preview 3 (was upgraded preview 2 solution) uses untyped viewmasterpage so:

public partial class home : viewmasterpage

on home.master there display statement this:

<%= ((genericviewdata)viewdata["generic"]).skin %>

however, developer on team changed assembly references preview 4.

following this, code no longer populate viewdata indexed values above.

instead, viewdata["generic"] null.

as per this question, viewdata.eval("generic") works, , viewdata.model populated correctly.

however, reason solution isn't using typed pages etc. because kind of legacy solution. such, impractical go through large solution , update .aspx pages (especially compiler doesn't detect sort of stuff).

i have tried reverting assemblies removing reference , adding reference preview 3 assembly in 'bin' folder of project. did not change anything. have tried reverting project file earlier version , still did not seem fix problem.

i have other solutions using same technique continue work.

is there can suggest why has stopped working , how might go fixing (any hint in right direction appreciated)?

we made change because wanted bit of symmetry [] indexer. eval() method uses reflection , looks model retrieve values. indexer looks @ items directly added dictionary.
