The OpenJPA documentation is very spare about it (Chapter 5.7 of the reference guide just lists the interface's methods - there are no hints about the results and the Magazine entity is not complete).
My questions: 1) There is no way to dynamically create a new FetchPlan at runtime? I have to declare FetchGroup by annotations first in order to use the FetchPlan feature? 2) When I have an entity with 15 fields and I would like to load only two of them (no relations), I have to create a FetchGroup accordingly. In the next step I execute OpenJPAPersistence.cast(...), add my FetchGroup and then what exactly do I get? My entity with the two fields only? My entity with two fields filled and the remains initialized to default values? 3) What will be the result if the entity has some relations? Are they initialized with "null" if they are not defined in my custom FetchGroup? I'm using OpenJPA 1.2.3 so please keep that in mind when answering.
