I have a problem with the following things:
@PersistenceCapable(detachable = "false", identityType =
IdentityType.APPLICATION)
@Inheritance(strategy = InheritanceStrategy.SUBCLASS_TABLE)
public abstract class Person {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName = "datanucleus", key = "gae.encoded-pk", value
= "true")
protected String id; //encoded string
}
public class Employee {
... // some persistent attributes
}
public class FemaleDaoImpl extends RemoteServiceServlet implements
FemaleDao {
/**
* Persists one employee obj
*/
public Employee create(Employee entry) {
PersistenceManager pm = PMF.get().getPersistenceManager();
try {
pm.makePersistent(entry);
}
finally {
pm.close();
}
return entry;
}
}
//THE CALL
public Request daoCreate(Employee entry) {
AsyncCallback<Employee> callback = new
AsyncCallback<Employee>() {
public void onFailure(Throwable caught) {
}
public void onSuccess(Employee result) {
Window.alert(result.getId()); //
<-------------- RETURNS NULL???
...
}
};
return dao.create(entry, callback);
}
----
Okay, when debugging this, the debugger tells me that , at the 'return
entry' line, it has a generated id. So I know that on the server it
gets an ID. but when it comes back the id is null again!
I used detached=false, because of this serialization issue, but that's
not a problem. I also tried copying the object I return attribute-by-
attribute, but it also ended up with an id being reset as soon as the
onSucces() is called.
Any ideas?
Oh lastly, i got another object, which is not part of a inheritance,
eg.
public class Hobby {
String id;
}
Storing this in a similar function works fine!
I've run into a wall here, is it a GWT bug? Or am I missing something?
