Hi Everybody, Here's my problem with JDO and unowned relationships :
I have several entities of the same kind that are organized in a hierarchical way, maintained with unowned relationships. JDO can generate keys for my entities when they are written to the datastore, but with this option, I can't know my entity's keys until they are saved to the datastore. If I want to make a reference to an entity A from an entity B, it seems to be impossible because at this time I don't know A's key, that will be generated when transaction is committed. One solution would be to use several transactions, each one would persist an entity, but it's not good because I want to persist all the entities in the same transaction. I know that defining keys myself could solve the problem, but maybe there is an other solution that would be better ? Thank you for your help. And thank you to the GAE team for the fantastic work you did ! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
