Retrieving entities with Request Factory.
I have following method which should return a list of PollProxy.
public ListPollProxy getPollList(){
ListPollProxy polls;
requestFactory.userRequest().findUser(Cookies.getCookie(user)).with(polls).fire(
new ReceiverUserProxy(){
@Override
public void onSuccess(UserProxy user){
polls=user.getPolls();
}
});
return polls;
}
but I can't figure out how to use the list returned by user.getPolls()
outside the onSuccess() . As polls field can't be accessed inside an inner
class. Please fix this method for me?

I am able to persist this entity in a servlet with following code: PersistenceManager pm = PMF.getInstance().getPersistenceManager(); User abcd = new User(); abcd.setEmail(em...@email.com); abcd.setName(name); VerificationToken token1 = new VerificationToken(abcd,VerificationToken.VerificationTokenType.emailVerification,60); if(abcd!=nulltoken1!=null) abcd.addVerificationToken(token1); else System.err.println(Why me!); Poll poll = new Poll(); poll.setQuestion(Hello Good Morning); ListString options = new ArrayListString(); options.add(option 1); options.add(option 2); poll.setOptions(options); poll.setUser(abcd); poll.setCloseTime(new Date()); pm.makePersistent(abcd); pm.makePersistent(poll); pm.close(); -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Entity not persisted, using JDO,RequestFactory.
I am still not able to persist poll entity using Requestfactory in GWT.
Please point out if there's anything wrong with following code.
view.setMsg(preparing);
PollRequest pr = requestFactory.pollRequest();
UserRequest ur = requestFactory.userRequest();
final UserProxy[] oldUser=new UserProxy[1];
ur.findUser(Cookies.getCookie(user)).fire(new ReceiverUserProxy(){
@Override
public void onSuccess(UserProxy user){
oldUser[0]=user;
}
});
UserProxy editUser=ur.edit(oldUser[0]);
PollProxy createdPoll = ur.create(PollProxy.class);
createdPoll.setQuestion(view.getQuestion());
createdPoll.setOptions(view.asEditor().getList());
createdPoll.setCloseTime(closeTime);
createdPoll.setUser(oldUser[0]);
editUser.setPolls(createdPoll);
ur.persist().using(editUser).fire(new ReceiverVoid(){
@Override
public void onSuccess(Void arg0){
view.setMsg(POll Created);
}
});

Entity not persisted, using JDO,RequestFactory.
I am trying to persist this http://pastebin.com/7KtXaBGe entity using
following piece of code:
PollRequest pr = requestFactory.pollRequest();
PollProxy createdPoll = pr.create(PollProxy.class);
createdPoll.setQuestion(view.getQuestion());
createdPoll.setOptions(view.asEditor().getList());
createdPoll.setCloseTime(closeTime);
createdPoll.setUser(Cookies.getCookie(user));
RequestVoid createReq = pr.persist().using(createdPoll);
createReq.fire(new ReceiverVoid(){
@Override
public void onSuccess(Void arg0){
view.setMsg(PollCreated);
}
@Override
public void onFailure(ServerFailure error){
Logger logger = Logger.getLogger(PollPersistError);
logger.log(Level.SEVERE,error.getMessage());
}
});
But it doesn't get persisted.There are no exceptions. What could be wrong?

Exception while persisting an entity.
While persisting following entity I am getting a server error : null in GWT
development console. But on removing the call to pm.persist() everything
goes right. I have doubts that I have not defined this entity properly.
Maybe I am using types not supported by Datastore.Or is there anything else
I am doing wrong? Please please help it's been a week I am following this
long chain of exceptions with this GWT project.

Re: Uncaught umbrella exception.
Thanks Thomas. Your solution is right. Now I have to do this http://vivagwt.blogspot.in/2011/09/requestfactory-en-gwt-24.html but how do I add requestfactory-apt.jar annotation processor to my project manually.

Implementing a service using request factory : static method in a type vs instance methods in a service class
I'm using JDO with RequestFactory and MVP pattern. Example to implement service in firty way is very clear to me from https://developers.google.com/web-toolkit/doc/latest/DevGuideRequestFactory#entity_service But how do you implement a service as instance methods in a service class? I am not very clear with the definition and use of ServiceLocator , Locator. When do you use them?
