Adam, the new deserealized object doesn't contain ANY data which was in original object instance.
To put it simple 1) we have obj 2) we make a string obj.SerializetoString ( & body) 3) We parse the string into new object : newobj.ParseFromString ( body). 4) I expect obj == newobj. But it isn't so. newobj is not equal to obj ( in terms of content - field value) Thanks, Boris On Wednesday, May 29, 2019 at 1:41:48 PM UTC-4, Adam Cozzette wrote: > > Hmm, that makes me think perhaps everything is working then.
