My mini server is on 10.7.3 like my Pro. Yet the server (checked Make available for home directories over AFP) shared folder "...does not support permanent version storage." from Numbers. It does from TextEdit (Revert Document... works). So does our iDisk. So it seems more like a Numbers bug than an OS or network one.
Also see first problem with saving edited files in Numbers at

I am having this error as well, except the destination is the hard drive of a different computer that is also running Lion. Any idea why I would get this error in this case?
And yet

The document versioning feature of Lion works with Mac OS Extended (HFS+) volumes that are directly connected.
Network connections to volumes over AFP, SMB, or NFS do not preserve previous versions of a document.
but TextEdit still does anyway.
