Hi, This is very probably a question related to Objectfify that is a package independent, i.e 3rd party, of App Engine. You should ask it there http://groups.google.com/group/objectify-appengine.
Question though: do you have a no-arg constructor in your class source code ? It's required. regards didier On Jan 1, 10:20 pm, Ueli Niggli <[email protected]> wrote: > Hello everyone > > I added some propertys to a class which I use to store objects in a > datastore.
