How to check for modifications from Palm to iCal via iSync...

Hi All,
if we modify a iCal event using iCal both “SEQUENCE” and “DTSTAMP” are modified accordingly and that’s fine.
If we modify the same event on Palm and sync (via iSync) the fields are modified in iCal but the fields “SEQUENCE” and “DTSTAMP” are unchanged.
How can we recognize with Apple Script that this event has been modified ?
We need to post the same modification on our application.
Does iCal keep a log of modification during the syncing session ?

We desperately need a solution… :frowning:

Thanks in advance.
