Hi, all,
I am still encountering some problem with JsonpRequestBuilder. I hope
anyone may point out what's why with my code.
Basically I have a json server which emits the following data:
====
[{'Article': {'title': 'Main test2010-03-17 19:21:54.865390'}},
{'Article': {'title': 'Main test2010-03-17 19:25:19.773520'}}]
====
On GWT front, I have
====
public void onModuleLoad() {
JsonpRequestBuilder requestBuilder = new JsonpRequestBuilder();
requestBuilder.setCallbackParam("callback");
requestBuilder.requestObject(SERVER_URL, new
MyTestRequestCallback());
}
class MyTestRequestCallback implements
AsyncCallback<JsArray<Article>> {
@Override
public void onFailure(Throwable caught) {
Window.alert("Failed to send the message: " +
caught.getMessage() +
" " + caught.getStackTrace()[0].toString());
}
@Override
public void onSuccess(JsArray<Article> result) {
Window.alert(result.get(0).getTitle());
}
====
And here is my definition of Article class
====
public class Article extends JavaScriptObject {
protected Article() {};
public final native String getTitle() /*-{ return this.title; }-*/;
}
====
The problem is: the result of "result.get(0).getTitle()" is always
null.
Setting the break point in the onSuccess() does not help much. The
content of the valuable is a 'ref n' where n is a number (in the debug
perspective of eclipse)
My questions are
1) What is the likely cause of the failure of capturing 'title'? Any
obvious error in my code?
2) I tried to debug in firebug, but failed to locate where the parsing
of json occurs. When I compiled the project, I used "output style" =
detailed. When I search for ".title" i could not find anything.
Shouldn't the native code be captured in the generated gwt code
intact?
Cheers
