Hi Frusty. I'll need some more information in order to help you: 1. Application ID 2. Content of servlet mapping to addContact endpoint 3. Definition of JDO/JPA class for your Contact data
Did you change the schema by any chance -- perhaps using a Text instead of a String? If so, there might be an issue transforming the String data in older entities to the Text type. Try removing your local.db file to clear out your local datastore to see if that fixes the issue. - Jason On Sun, Aug 23, 2009 at 3:39 PM, Frusty <[email protected]> wrote: > > Hi, > > I am having a big problem with my GAE Project. > > I want to store some Contact data and that worked perfectly. > > Since i do not like the way GAE generates the keys, I am now using the > String ID to define my own key.
