...more stacktrace

He creado un clon de boceto de clase exacto llamado Sketch2 y creó clones de Sketchdao, SketchProxy y SqetchRequest en mi interfaz requerida.

Excepción es de todos modos lanzada.(Intenté recompilar, reiniciar, limpiar archivos generados, intenté usar la idea - mismo problema) ¿Alguna idea de que esto está sucediendo?

Answer 1

You have to register classes that you want to use with objectify. Something like this:

factory.register(com.trial.gwtgae.server.domain.Sketch2.class);
