I am using a UID as the filename for new iCalendar files PUT to the

the original filename still retrieved the proper file.


However, it is no longer working:

I poked around in the .db.sqlite file and see that the "NAME" of the
"RESOURCE" is the same as the "UID" and there is no linkage to the actual 
filename ("2KXNZR~T.ICS" in this case).  I'm guessing that the "UID"
field used to match the actual filename on the server OR I'm doing
something wrong naming the file.  Should I submit a bug?
What OS are your running the server on? Do you have the latest top- of-trunk server code?
Mac OS 10.4 Server. I re-checked out the code today before sending an email just to be sure.
As far as I am aware the server does not rewrite the file name - it uses the last segment of the URI path as the name of the file. So I am not sure why you are seeing that truncated/changed in your file browser.

OH!! It just hit me, for viewing the files I'm connected to the server through the Finder using Samba and these filenames have a colon in them. A quick check on the command line verifies that the filename is indeed how you say it should be. Sorry for the scare, I confused myself by accident.
However, the REPORT still fails with the above error although I have no problem seeing the collection and getting files through the browser (both GETs).
Since the filename is 007-04-11T10:52:00-0600_822729681.ics and the error refers to 2007-04-11T10%3A52%3A00-0600_822729681.ics, is there an escaping issue? 

Thanks for the quick response,
