Public action method was not found on controller

Question

I have the following controller method:

public ActionResult GetResults(string viewToReturn, int resultsPerPage, 
          string classification = null, string sessionId = null, int? lastId= null)
{
               ...
}

Calling the method above via the following url:

http://localhost:63455/Home/GetResults?viewToReturn=grid&resultsPerPage=30

results in an exception thrown with this message:

A public action method 'GetResults' was not found on controller 'MyWebSite.Controllers.HomeController'.

and here is the RegisterRoutes:

......    
routes.MapRoute("Home", "home/{action}/{*qualifier}",
       new { controller = "Home", action = "Index", qualifier = UrlParameter.Optional });
......
routes.MapRoute("SearchTitle", "{*path}",
       new { controller = "Home", action = "SearchTitle", path = UrlParameter.Optional });

Why am I getting this error and how do I fix it? Thanks!

Solution

I had the [HttpPost] attribute on the method. I could swear that I removed it earlier, but somehow after I took a break and came back, I saw it. After removing it, everything now works fine.

Yes how confusing, this "gotcha" will surely catch new developers sooner or later. Perhaps the best practice should be AcceptVerbs only then until Microsoft fix this un-necessary limitation, e.g. stackoverflow.com/questions/3843875/…
