I am able to edit the metadata of files within containers successfully, but editing container metadata appears to be impossible. When I attempt to edit a container's metadata (to enable versioning for example) a "System.ArgumentOutOfRangeException" is thrown when I leave the metadata tab and return to it. Also, unlike editing file metadata the container is not immediately re-uploaded to the server like files are.
The Log Drawer does not display anything to reflect this issue.
Add a header (any kind, it doesn't seem to matter) to a Rackspace Cloud Files Container.
Note that container is not updated in the Log Drawer.
Switch to another tab in the info window.
Return to metadata tab.
Receive error window and notice that the added header is now missing.
