Load GridPanel via WebService fails with Server Error 500
Hi,
I get following Error:
Server error in Application. Unkown request format for an URL which ends unexpected with '/GetAllCategories'
Status Code: 500
Status Text: Internal Server Error
(translated from German: "German: Serverfehler in der Anwendung" Unbekanntes Anforderungsformat für einen URL, der unerwartet mit '/GetAllCategories' endet.)
How can this problem be solved? Please see the relevant code:
The code files are in the same directory.

(Line 40 has the entry for the web service)
