[jQuery] "No element found" when firing $.post()

[jQuery] "No element found" when firing $.post()


Hello together,
just a short question: by firing a request via POST to the server side
Firefox shows an "No element found" (in German "Kein Element
gefunden") in its Error console (Firebug displays nothing). Example:
$.post("/Portal/ReorderPortlets", { portlets: $("#portal").sortable
("toArray") });
I am a bit confused, could anyone bring some light into this?
Thanks :)
Thomas
