I am using a UID as the filename for new iCalendar files PUT to the server (ex. 2007-04-11T10:07:13-0600_477504818.ics) and I noticed that these files were always renamed on the server (ex. 270IQ6~Y.ICS).  But 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?
