I have followed your tut and liked it a lot.

At my appspot I get:

[RPC Fault faultString="[MessagingError message='Destination 'Data' either does not exist or the destination has no channels defined (and the application does not define any default channels.)']" faultCode="InvokeFailed" faultDetail="Couldn't establish a connection to 'Data'"]

Also, locally I can not run the server. I get:

One blog says something about adding -services to Flex Compiler settings but not sure what this all about.

Can you include the source code as zip? Just so that I can compare

Great article. Thanks for sharing.

Not sure which part is not right. After I followed everything, I kept on getting

Great job on the tutorial, I have been able to follow the steps and get it to work.
I am trying to build an application using these technologies.
My problem is that I can not figure out how to pass user defined objects from Flex to the server.

Basically, I would like to have the ability to pass Objects back and forth as bellow:

public void createDataItem(Data data) {
....
...
}

I would appreciate some help with this.

Thanks

Am also keen to know if you have any insights of using Flex client v/s GWT in the context of GAE-J

Many thanks!

2010-01-02T04:20:22.509-08:00

Thanks you for the nice tut. I've followed it step by step and able to finish with success. I'm having problems while getting KEY from datastore. I'm querying like;

EntityManager em = EMF.get().createEntityManager();
Query query = em.createQuery("select from MenuItem");
return (List) query.getResultList();

Everything works fine except the KEY field, I couldn't get it but all other fields are retrieved. Is there and special way to get the key fields? I've been searching for 3 hours but couldn't find an answer about it. BTW I've declared my key field as;

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Extension(vendorName="datanucleus", key="gae.pk-id", value="true")
private Long KEY;

Thanks for the nice tut again.
