Hi, Your problem is a know issue on the SDK for a long time: see http://stackoverflow.com/questions/1641697/google-app-engine-jdo-and-equals-hashcode and many others: see http://www.google.com/search?hl=en&source=hp&q=class+not+enhanced+app+engine
What I do to fix it is that I manually declare 1 by 1 my classes in go to Eclipse -> Project Settings -> Google -> App Engine -> ORM and remove the original generic definition in that place Then, the problem never appears again: classes are processed by SDK enhancer when needed. regards didier On Aug 31, 3:57 pm, leonardo battagli <leonardobatta...@gmail.com> wrote: > I am using google plugin for eclipse, I have only a jpa class and I > have been able to store some data yesterday.
