hi jbdhl I wish there was an easy answer too - but I suppose at least we have choice! My experience, which I hope will at least help you a bit For back ground I am transferring a prototype developed using a db4o back end, but had little done for the UI. There are a lot of relationshi

Hi Christian That's interesting ... I just felt that I wanted to manage the references (keys) myself, so I could have more control over when and how those references are instantiated - Twig seems to do that for you (great in many ways), but I have some situations with my application where I think

I didn't try, but I'm sure that if you set a Key field that doesn't exist in the datastore, it will be stored with the key you wanted. If I recall, store only auto assign a key when the key field is null or doesn't exist. @Key private long id; Christian On Mon, Apr 26, 2010 at 7:59 AM, David Sow
