Hi, scuse my bad english, I'm french. Since 3 days I try Google App Engine to deploy a GWT app. I use JDO to manage my entities. I can persist my data in the DataStore but when I try to read joins Entities are set to null.
My joint is a OneToOne and I use the follow code to create my PrimaryKeys : @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) @Extension(vendorName="datanucleus", key="gae.encoded-pk", value="true") I can get my joins entities when I add @Persistent(defaultFetchGroup = "true") but console say's : The datastore does not support joins and therefore cannot honor requests to place related objects in the default fetch group. The field will be fetched lazily on first access. Can you help me to find a proper solution ?
