I'm quickly running out of ideas, but perhaps one of these two would work
to make sure the ObjectContextProvider is available up-front:
#1 Use an AppModule constructor
public class AppModule
{
private final ObjectContextProvider objectContextProvider;
public AppModule(ObjectContextProvider objectContextProvider)
{
this.objectContextProvider = objectContextProvider;
}
@Startup { ... }
}
#2 Use @Inject
public class AppModule
{
@Inject
private ObjectContextProvider objectContextProvider;
@Startup { ... }
}
If neither of those work, perhaps the T5 list would be more helpful. I'm
pretty sure Robert Ziegler, who wrote the T5-Cayenne module, follows that
list.
