Hi, I think at this point that Max's knowledge is needed.... Max could you report on this thread please??? Thanks datanucleus wrote: Perhaps GAE/J doesn't respect that metadata extension tag then. Raise a bug on their DataNucleus plugin for it. Not related to JDO but... parent-child relationships are really simple to define with Twig... you don't need to use keys at all. FWIW You don't need "Key"s ***in JDO*** at all either ... when the JDO interface is respected and implementation details don't leak out into user space; keys should not be presented to the user IMHO. JDO is then a very good option whether you want your code to run on another platform or not. -- Patrizio Munzi Product Specialist Viale Bruno Buozzi, 19 - 00197 Roma (Italy) tel: +39 06 4543 3540 fax: +39 06 4543 3587 mobile: +39 393 7195 164 mail: patrizio.mu...@eris4.com web: http://www.eris4.com skype: eris4_munzi --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
