Summary - #3229 - @-sign in UID make caldav/lightning not working 
Hello, 

 I try to create an event by importing a ics through thunderbird/lightning. The event get's created but it does not show up in lightning anymore. I suspect the @ in the filename to be the bad point. I am not sure if egw or lightning is to blame, so also a bug at mozilla is filed.

 https://bugzilla.mozilla.org/show_bug.cgi?id=766977 

 I attached a wireshark log and the ics file.

 Lightning is 2.4a2 and egw is uptodate svn 1.8.004.

 Thanks

 Christoph

Hi Ralf, 
 I think the problem is, that lightning constructs a filename from the UID which contains a @ sign. 

 The file is created in egw, it is there and found by other clients, but not by lightning anymore. 

 In the query for files I can see the hex description for the @sign, and egw doesn't deliver the file. 

 Maybe it is a lightning bug, but I am not sure.

 Doing some tries with cadaver the point seems to be if the @ is masked in the get command, I don't know what is the correct behaviour:

 dav:/egroupware/groupdav.php/calendar/> get BAHN@Fahrplan.ics hhhfff.ics
 Downloading `/egroupware/groupdav.php/calendar/BAHN%40Fahrplan.ics' to hhhfff.ics:

Hi Christoph,

 EGroupware does NOT generate UIDs with an @-sign. Our UIDs use following form 

 --

 But you can import ics files or CalDAV clients can add events, which contain arbitrary UIDs.

 AFAIK there's no strong specifiction about format of UIDs.

Just tested with a trunk from yesterday, it doesn't work here either.
