there is strange behviur with routing , i do not know that am i doing wrong and what i am doing wrong

i am calling a action in a controller when i call it with id it works but when i try to call it without id it do not work

origanlly my global file was like this

"Default", // Route name

"{controller}/{action}/{id}", // URL with parameters

new { controller = "Home", action = "Index", id = "" } // Parameter defaults

"Default2", // Route name

"admin/manufecturer/Edit/{id}", // URL with parameters

new { controller = "manufecturer", action = "Edit", id = "" }, // Parameter defaults

"Default21", // Route name

"admin/manufecturer/New/{id}", // URL with parameters

new { controller = "manufecturer", action = "New", id = "" }, // Parameter defaults

new { controller = @"[^\.]*" });

but i also tried that with other variation too

"Default21", // Route name

"admin/manufecturer/New/", // URL with parameters

new { controller = "manufecturer", action = "New" }, // Parameter defaults

new { controller = @"[^\.]*" });

but without id its not workin , what i am missing ,

Ahtesham

 On your action methods in controller, id need to be nullable

 and in your route table, always set Default route as last in the list.

why is that when i put null in id it works

"Default2", // Route name

"admin/manufecturer/Edit/{id}", // URL with parameters

new { controller = "manufecturer", action = "Edit", id = (string)null }, // Parameter defaults

"Default21", // Route name

"admin/manufecturer/New/{id}", // URL with parameters

new { controller = "manufecturer", action = "New", id = (string)null }, // Parameter defaults

"Default", // Route name

"{controller}/{action}/{id}", // URL with parameters

new { controller = "Home", action = "Index", id = (string)null } // Parameter defaults

 Not exactly what I meant. I mean

public ActionResult SomeAction(int? id) {

 // Do something

}

what parameters does your controller actions receive?
