Hi,
Please let me know if this is not the place for this kind of questions...
I am using *Objectify* with *RequestFactory*. I have an objectify
*Entity*called
*Entry* with an attribute of type Ref*<?>*. Following
*Objectify*recommendations, I declare the getter and setter for that kind of
argument
as:
* @Parent Ref<Topic> topic;*
*public Topic getTopic() {*
* return topic.get();*
* }*
**
*public void setTopic(Topic topic) {*
*this.topic = Ref.create(topic);*
*}*
*(Topic is an Entity as well)*
Now on the client side I want to create a new *Entry* with some user
content and attach to that *Entry* the *Topic* which I happen to have
already in the client (brought it before with *RequestFactory*). So I do:
entry.setText(review); //an String
entry.setTopic(topic);
entryService.saveEntry(entry).fire(new Receiver......)
However, I always receive a very weird null Exception on the Receiver's
onFailure:
- getMessage gives: Error: Server Error: null
- stacktracestring is null
- requestContext is com.mmr.shared.service.EntryServiceImpl@5d95bef6,
which is my service implementation but I have put a breakpoint and it never
gets in.
When I remove the *setTopic* call, the service succeeds (as long as I deal
with the then null argument). So I believe the problem is in the setTopic
but I don't know how to solve it neither how to workaround.
Can you help me? I am a newbie to GWT and Web programming in general but
this seems to me like pretty basic functionality in order to add items to a
graph.
Thanks!
