[OGo-Users] ics calendar files

[Peter Duda]

Ok this is a bit of a bonehead move on my part - 
While testing the new thunderbird calendar, I neglected to backup my
database before playing around
Yeah I know - it says everywhere to backup your data, but . . 
So I was testing the Dav connector with the 0.8 calendar pre-release (which
doesn't seem to work right just yet), and then decided to see how ical
worked - and when I saved a new event it removed all the participants on all
my appointments, so now nothing shows up in the webui.
Somewhat fortunately 0.8 now has a cache so I can get the original ics file
that I downloaded, the problem is that it is not saving the participants
The errors that I get for individuals are
"participant has no company-id"
The errors that I get for groups are
"got a staff-id which is nil"
A single event looks like this

BEGIN:VEVENT
CLASS:PUBLIC
LOCATION:Guild Hall

So my question is - What is the format of the data that is "missing", and If
I insert this info into the ics file and reload it - will it save the
participants?

Thanks
Peter
