I have two value encoders: LibrarianEncoder and ReaderEncoder.
*LibrarianEncoder.java*
@SuppressWarnings("rawtypes")
public class LibrarianEncoder implements ValueEncoder {
private Session session;
public LibrarianEncoder(Session session) {
this.session = session;
}
public String toClient(Object arg0) {
return ((Librarian)arg0).getId().toString();
}
public Object toValue(String arg0) {
return session.load(Librarian.class, new Long(arg0));
}
}
Seccond Encoder is like this one.
*AppModule.java*
@SuppressWarnings("rawtypes")
public static void contributeValueEncoderSource(
MappedConfiguration<Class, ValueEncoderFactory>
configuration,
@InjectService("session") final Session session) {
ValueEncoderFactory librarianFactory = new
ValueEncoderFactory() {
public ValueEncoder create(Class arg0) {
return new LibrarianEncoder(session);
}
};
ValueEncoderFactory readerFactory = new ValueEncoderFactory() {
public ValueEncoder create(Class arg0) {
return new ReaderEncoder(session);
}
};
configuration.add(Librarian.class, librarianFactory);
configuration.add(Reader.class, readerFactory);
}
The problem is that i have conflict:
Exception constructing service 'ValueEncoderSource': Error invoking service
builder method
org.apache.tapestry5.services.TapestryModule.buildValueEncoderSource(Map,
InvalidationEventHub) (at TapestryModule.java:2287) (for service
'ValueEncoderSource'): Error invoking service contribution method
com.fit.library.services.AppModule.contributeValueEncoderSource(MappedConfiguration,
Session): Service contribution (to service 'ValueEncoderSource') conflicts
with existing contribution (by
org.apache.tapestry5.hibernate.HibernateModule.contributeValueEncoderSource(MappedConfiguration,
boolean, HibernateSessionSource, Session, TypeCoercer, PropertyAccess,
LoggerSource) (at HibernateModule.java:89)).
How to resolve this?
