Aparna and Andre have been investigating a bug where Andre gained read-write access to a Chandler item he received via email by adding it to a second shared collection he has read-write access to.

As a result, Aparna and I were seeing Andre's non-emailed edits on the item and vice versa, even though we never set up a formal sharing relationship by exchanging read-write ticket URLs for a commonly shared collection.

Randy, Morgen, could you give us on the design list an update on where you are wrt this issue (or point us to the latest dev-list write-up)?

Ah yes my favorite topic.  I've started a page with some notes:

http://chandlerproject.org/Journal/CosmoAccessControlNotes

There hasn't been much discussion on the cosmo-dev list so far (probably because people go crazy after reading the notes). Morgen and I talked about ideas today (I've updated the notes page with thoughts at the bottom) and both of us are leaning towards storing copies of items on the server (one item per account) rather than a single item (the way it is now). This is actually going back to the way the server *used* to work. The only problem with this is that it presents some problems with the web ui when an item in multiple collections is updated (mainly that the webui doesn't support this and will only update a single collection).

Also, the client bug for this is:

I don't think there is a server bug opened yet.
