On that line I have studioService.save(tempStudio); DummyDataGenerator generated the dummy code for the database and it doing so using the service that are defined in the bind method. Is it possible that the services are are not defined?

Re: Creating custom service using build() failed
The service is just a hibernate service that saves data to the database.
public class StudioServiceHibernate implements StudioService {
private final Session session;
public StudioServiceHibernate(Session session) {
this.session = session;
}
public Studio save(Studio studio) {
return (Studio) session.get(Studio.class, session.save(studio));
}
}
I was looking at the execution order.
First it executes the bind method which binds all the services including
binder.bind(StudioService.class, StudioServiceHibernate.class);
After that it give control to the
@Startup
public static void initApplicationData(DataGenerator dataGenerator) {
dataGenerator.generate();
}
which should fill in the database. Since the DataGenerator is created with
the build method it then triggers this method
public static DataGenerator buildDataGenerator() {
return new DummyDataGenerator();
}
Which creates generator and then starts to generate the method. Inside it
are the services for filling the database like StudioService which is
injected into the Generator class. However for some reason it is as if the
bind method didn't bind the StudioService to its implementation.
When I remove the buildDataGenerator and manually bind it inside the bind
method all is ok. But when I put it in special method it is not.
What am I missing? Idea?
Thx for trying to help

Re: Creating custom service using build() failed
I solved or at very least I am aware how to bypass the problem. It seems that the services can not be injected into the DummyDataGenerator if I create it using the build method but if I create it in the bind it can inject the service. The only problem is that I have about 20 service so can you imagine the argument list :( Any idea if it possible to solve this in a cleaner way because now I will have to modify argument list every time I want to add or remove service.

Re: Creating custom service using build() failed
Instead of
public static DataGenerator buildDataGenerator() {
return new DummyDataGenerator();
}
try
public static DataGenerator buildDataGenerator(ObjectLocator locator) {
return locator.autobuild(DummyDataGenerator.class);
}
When you use new DummyDataGenerator(), @Inject won't work
