I have written a little controller to return a Object from passed id. All works A OK! with one exception.

If the url is submitted like this http//www.example.com/processattendees/send/50000004527-49230 all is ok.

The problem is that if the url is submitted like http//www.example.com/processattendees/send/50000004527/49230 it breaks the controller.

I'm assuming that the controller is getting lost because of the extra forward slash. Is there anything I can do in the controller to stop the extra slash breaking things?

Any help or pointers would be greatly apreciated.

The extra slash is making the controller think there's another step in the URL. You might need to tweak your url handling.
