> 1. Go to the extendedDataTable showcase
> 2. Turn on ajax loading.
> 3. Open the debugger of your browser and watch the network communication
> 4. Scroll down in the table untli new data has to be fetched.
> => one POST request is sent. This is fine.
> 5. Change the width of a column in the table.
> => one POST request is sent. This is fine.
> 6. Scroll again in the table untli new data has to be fetched.
> -> 2 POST requests are sent. WHY?
> From now on, on each scroll, the table always sends 2 requests. This behavior
> stops only when your relaod the table.
> Due to this behavior I get some perfromance issues, as I have to execute some
> own javascript after each request.
> Is there a possibility to prevent the 2nd POST request. I would be happy even
> with a dirty hack, or just a hint showing me from where the 2nd request is
> triggered.
> Best regards
> wlh
