@kalbermattenm : You'll probably kill me for this major revision in one chunk, but could you please review ?
thanks!!!
there is a lot of commented code in admin_functions.py because in a first step I did not yet implement the filtering there
You are using `Crdppf.labels` here. This variable is defined by the success function of an Ajax request.

What happens if you defined `contentPanel` before the Ajax request has succeeded, thus you navigator has read you code before the request ended ?
