Re: [eGroupWare-users] Iphone calendar and CALDAV

Yup that is the same error we get as well... 404 Not Found and we
haven't figured out why.

Hi,
the 404's in a 207 Multistatus are no problem, it just tells the client,
which attributes are not supported by the server.
Here's the interesting part:
REPORT /eg/groupdav.php/calendar/ HTTP/1.1
Host: 192.168.252.241
User-Agent: DAVKit/4.0 (728.3); iCalendar/1 (34); iPhone/3.0 7A341
Authorization: Basic (password_removed)
Content-Type: text/xml

Connection: close














So the iPhone asks for all calendar events after 21th Mai 2009 22h.
And EGroupware answers there are none.

Just from looking at the request and response, I can not tell if that's
correct, or if EGw can not parse the query.
One problem could be, that time-range only has a start but no end attribute.
Do you get anything in Apache's error_log like:
- calendar_groupdav::_report_filters(...) unknown filter --> ignored
- calendar_groupdav::_report_filters(...) param-filter=3D'xxxxxxxx' not
(yet) implemented!"
Looking into iPhone problems with our CalDAV is on our (Stylite GmbH)
todo. It will happen in next 1-2 weeks probably.

Hi friends
I have the same problems with syncing my iphone with the egroupware
calendar. I realized, that the iPhone automaticly removes the last "/" when
I insert the eGroupware link. For my config it means, that I write
"http://mysite.com/myegroupware/groupdav.php/calendar/" and the iPhone
removes the last slash. So the url changes to
"http://mysite.com/myegroupware/groupdav.php/calendar" and as I red in some
other threads, this creates problems with syncing.
Could that be the reasen for all of our problems with the iPhone 3.0?
greets

Just one question
Is CalDav a real sync or a remote access ?
I mean : for me, sync is a process which takes tada from server and paste
them in the client (the first time) and after compare data in the client and
server and finaly add or remove each side if necessary. With this, in the
client (ie iPhone), you have data independently and you can read / modify
them without connexion to the server. In the case of a remote access, you
need to have access to the server to read or modify data.
This is important, because in the iPhone case, I don't think that remote
access is a good solution, just because i'ts a mobile device and you can't
have the guaranty that you will have an Internet access all the time you
need to. That's why I think thas pure sync like syncml is a better solution.
It's not the case of PC which is allways connected : in this case, remote
access is a better solution.
YL

Hi Lannehoa,
with CalDAV it depends on the client.
Client can do a PROPFIND to get the etag's of all entries. If the etag
is different from the one he caches, he can use a GET or MULTIGET to
request just the updates.
