What would be your suggestions? this is possible in the new version of PersistentObject (currently in beta status, but expected to get RC next Monday). In this version, we added a feature called "identity map", which allows you for example to fetch related objects of arbitrary depth in one JOIN. For more detail, take a look at the tutorial shipped with the beta [1]. I'm sorry, that the docs for this feature are not rendered online, yet. They will come on Monday, latestes.
