Actually, I took a look at these docs and it seems like we do talk about cross group transactions. There are a few areas where we talk about exceptions being thrown for transactions on entities in different entity groups, but that's expected behavior. You must specify that you want a cross-group transaction.
We'd definitely like to improve these docs, however. Do you have any suggestions or areas where this documentation seems confusing? -- Ikai Lan Developer Programs Engineer, Google App Engine plus.ikailan.com | twitter.com/ikai On Fri, Jan 13, 2012 at 12:23 PM, Ikai Lan (Google) <ika...@google.com>wrote: > Thanks!
