asp.net mvc handleerror

how i [handleerror] filter asp.net mvc preview 5?

i set customerrors web.config file

<customerrors mode="on" defaultredirect="error.aspx">
  <error statuscode="403" redirect="noaccess.htm"/>
  <error statuscode="404" redirect="filenotfound.htm"/>
</customerrors>

and put [handleerror] above controller category this:

[handleerror]
public category dswebsitecontroller: controller
{
    [snip]
    open actionresult crashtest()
    {
        pitch new exception("oh noes!");
    }
}

then i let controllers get category crashtest() them.
visual studio halts during blunder after dire f5 continue, i rerouted error.aspx?aspxerrorpath=/sxi.mvc/crashtest (where sxi name used controller.
off impetus route can't found i "server blunder '/' application." 404.

this site ported preview 3 5.
everything runs (wasn't many work port) solely blunder handling.
when i emanate finish new digest blunder doing seems work.

ideas?
