[appengine-java] Re: Problems with entity groups in transactions

[Patrizio Munzi]

I'm using these annotations, but it's not working. -----------------------     @PrimaryKey     @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)     @Extensions({         @Extension(vendorName="datanucleus", key="gae.encoded-pk", value="true"),         @Extension(vendorName="datanucleus", key="strategy-when-notnull ", value="false")     })     protected String encodedKey;     @Persistent     @Extension(vendorName="datanucleus", key="gae.pk-name", value="true")     private String id; ----------------------- I don't know if something else is needed. datanucleus wrote: No idea if GAE/J's plugin supports this extension property but we provide it in DataNucleus as a whole to only impose the "value strategy" for the field when it is null (i.e not already set by the user). Add this to the PK field that is being set @Extension(vendorName="datanucleus", key="strategy-when-notnull ", value="false") -- 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.
