hmmmmmmm... Strange. I do attache u a screenshot. It is made from the "firebug"-Debugview. Firebug is cool, it runs as an extension for firefox.
In the shown view, u have can see the transfered response from the PHP-File. When I do call the file directly, I get the right json-structure like u.
I would advice u to write a new, very simple PHP File (with a different filename ;-) ). The new file should just echo the json data.
