    copied!<p>I'm getting an intermittent exception saying that asp.net mvc can’t find the action method. Here’s the exception:</p> <blockquote> <p>A public action method 'Fill' could not be found on controller 'Schoon.Form.Web.Controllers.ChrisController'.</p> </blockquote> <p>I think I have the routing set up correctly because this application works most of the time. Here is the controller’s action method.</p> <pre><code>[ActionName("Fill")] [AcceptVerbs(HttpVerbs.Get | HttpVerbs.Post), UserIdFilter, DTOFilter] public ActionResult Fill(int userId, int subscriberId, DisplayMode? mode) { //… } </code></pre> <p>The route:</p> <pre><code>routes.MapRoute( "SchoonForm", "Form/Fill/{subscriberId}", new { controller = "ChrisController", action = "Fill" }, new { subscriberId = @"\d+" } ); </code></pre> <p>And here is the stack:</p> <blockquote> <p>System.Web.HttpException: A public action method 'Fill' could not be found on controller 'Schoon.Form.Web.Controllers.ChrisController'. at System.Web.Mvc.Controller.HandleUnknownAction(String actionName) in C:\dev\ThirdParty\MvcDev\src\SystemWebMvc\Mvc\Controller.cs:line 197 at System.Web.Mvc.Controller.ExecuteCore() in C:\dev\ThirdParty\MvcDev\src\SystemWebMvc\Mvc\Controller.cs:line 164 at System.Web.Mvc.ControllerBase.Execute(RequestContext requestContext) in C:\dev\ThirdParty\MvcDev\src\SystemWebMvc\Mvc\ControllerBase.cs:line 76 at System.Web.Mvc.ControllerBase.System.Web.Mvc.IController.Execute(RequestContext requestContext) in C:\dev\ThirdParty\MvcDev\src\SystemWebMvc\Mvc\ControllerBase.cs:line 87 at System.Web.Mvc.MvcHandler.ProcessRequest(HttpContextBase httpContext) in C:\dev\ThirdParty\MvcDev\src\SystemWebMvc\Mvc\MvcHandler.cs:line 80 at System.Web.Mvc.MvcHandler.ProcessRequest(HttpContext httpContext) in C:\dev\ThirdParty\MvcDev\src\SystemWebMvc\Mvc\MvcHandler.cs:line 68 at System.Web.Mvc.MvcHandler.System.Web.IHttpHandler.ProcessRequest(HttpContext httpContext) in C:\dev\ThirdParty\MvcDev\src\SystemWebMvc\Mvc\MvcHandler.cs:line 104 at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean&amp; completedSynchronously)</p> </blockquote> <p>Here is an example of my filters they all work the same way:</p> <pre><code>public class UserIdFilter : ActionFilterAttribute { public override void OnActionExecuting(ActionExecutingContext filterContext) { const string Key = "userId"; if (filterContext.ActionParameters.ContainsKey(Key)) { filterContext.ActionParameters[Key] = // get the user id from session or cookie } base.OnActionExecuting(filterContext); } } </code></pre> <p>Thanks, Chris</p>
