Hi Steve, We try to avoid backwards incompatible changes as much as possible.
You will get an expando when the decoded proto does not have a key (as in this case the correct model class cannot be determined, see http://code.google.com/p/googleappengine/source/browse/trunk/python/google/appengine/api/datastore.py#1086). Are you passing in an empty string to the decode function? Anything that produces an expando should have failed to encode and decode before (with an exception). Do you have a byte string ("print '%r' % encoded_proto") you can send me for testing? Thanks, Alfred On Sun, Jun 3, 2012 at 2:30 PM, Steve <unetright.thebas...@xoxy.net> wrote: > I'm mistaken.
