I don't really like that idea, as it means that forge then becomes part of your build process. 

With the @AutoHome it should not really matter about IDE auto completion, the idea is to just register a bean that allows you to lookup beans by ID from the EL.

The underlying bean would probably look like:

public class AutoHomeBean<T,ID> {

  private ID id; 
  private T instance; 
  void setId(ID id) {
  if(!this.id.equals(id) ) { //need NPE check as well
   this.instance = null;
}
   this.id = id;

 }

 ID getId() //getter;

 public T getInstance() {
   if(instance == null && id != null) {
    instance = em.find(...);
  }
  return instance 
 }
}

Then if you put the AutoHome annotation on MyEntity you would get a MyEntityHome bean being registered, and you could then do things like:

#{myEntityHome.setId(10)};

#{myEntityHome.instance.name}

Not sure how practical / useful it will be in practice, but that was the basic idea.

True. I don't really see the problem with having an object that extends a base object, even if it has no additional methods.

...and if that is the solution, then the @AutoCrud could be a hint to forge to generate that class if it doesn't yet exist. Now that's an idea :)

That's good at the runtime, but develop time that really doesn't help because it won't compile and you won't get IDE auto complete.

Stuart,

You also previous mentioned...

With portable extensions we could do something like:
@Entity
@AutoHome
public class MyEntity ....

and have a portable extension that registers a new home bean for every entity with the @AutoHome annotation.

I think we all agree that "Home" is a crappy name, so perhaps @Crud or @Dao would be a sufficient name.

My original plan for EntityQuery was to use the ServiceHandler stuff in solder:

@EntityQuery
public interface MyQuery {

  @Query("Select u from User u where type=:p1")
  public List<User> users(String type);

Yeah, I agree that being declarative is the ideal.
let's say no to inheritance with generics! hehehe.

Of course there're still boilerplate code, but I think it's minimal (compared to the JEE generations before), and that's something forge can create without the need to satisfy a "framework". Yes, I admitedly am afraid of that word.

That's fine, it doesn't have to be a framework. I do think there is room for having some common scaffolding, though. If we can do that by extending the programming model (annotations, generic beans or interfaces) so that it's declarative, that's probably ideal.

I suggest that we brainstorm proposals using gists (http://gist.github.com). That will get the ball rolling. We can start with the idea Jason posted, or feel free to take a different approach.
