AK, I'm not 100% positive, but it looks like this is how the Objective-C client is handling HTTP 413 Precondition Failed errors. This means that the entry you're trying to edit has already been modified by another process, and the Calendar API is preventing your changes from taking effect to avoid clobbering somebody else's update and losing data. Can you confirm that nobody else (including your application) has edited that entry since the last time you retrieved it? (If somebody else has edited it, the fix is simply to re-fetch the entry and try your edit again.) -- Trevor Johns --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Calendar Data API" group.
