Hi,
sorry I have to ask, but the example at
http://code.google.com/intl/en-US/webtoolkit/doc/latest/DevGuideRequestFactory.html
is relative unclear to me how about making the RequestFactory work with
Persistence function NOT in the Entity and not beeing static. I have not
found any examples. Could some one please help.
I am experience the following problem/exception with my implementation and
can see were the problem is:
@Service(value = EmployeeService.class, locator = DaoServiceLocator.class)
public interface EmployeeRequest extends RequestContext {
...
InstanceRequest<EmployeeProxy, Void> persist(EmployeeProxy employee);
}
ServiceImpl:
public class EmployeeService extends GenericDAO<EmployeeGWT, ObjectId>{
...
public void persist(EmployeeGWT employee){
em.save(employee);
}
}
Client call:
EmployeeRequest request = requestFactory.employeeRequest();
EmployeeProxy newEmployee = request.create(EmployeeProxy.class);
newEmployee.setDepartment("void");
newEmployee.setDisplayName("VoidMan");
Request<Void> createReq = request.persist(newEmployee).using(newEmployee);
I get the following Exception:
java.lang.IllegalArgumentException: object is not an instance of declaring
class
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57)

at java.lang.reflect.Method.invoke(Method.java:601)
at
com.google.web.bindery.requestfactory.server.ReflectiveServiceLayer.invoke(ReflectiveServiceLayer.java:182)
I am not sure what this means and looking for clues. Is the @Service wrong
or what is missing or wrong here? Maybe this is even totally unrelated to
my question?
kind regards
