GWT Native Method Warning

2012-11-19 Thread Patrax 
 
  
I'm doing a project in GWT to deploy in AppEngine and I'm getting a warning 
in Eclipse saying: JavaScript parsing: Expected an identifier in JSNI 
reference Any ideas on what's causing this?

public void callFacebookAPI(String url) {
JsonpRequestBuilder requestBuilder = new JsonpRequestBuilder();
requestBuilder.requestObject(url, new AsyncCallbackFbUser() {

public void onFailure(Throwable caught) {
System.out.println(FAIL );
}

@Override
public void onSuccess(FbUser result) {
facebookUser = result;
System.out.println(Facebook name: + facebookUser.getName());
}

}); 
}


private final native void doFbLoginFunction() /*-{


FB.login(function(response) {
if (response.authResponse) {
// connected
//return response.session;
var accessToken = response.accessToken;
var url = http://graph.facebook.com/me?access_token=;;

var facebookUrl = url + accessToken;

@com.google.gwt.smartpark.client.map.SmartPark::callFacebookAPI(Ljava/lang/String;Ljava/lang/
String;)(facebookUrl); 

} else {

This is an instance method.


 FB.login(function(response) {


[FYI, you should probably wrap your callback in $entry().  See
https://developers.google.com/web-toolkit/doc/latest/DevGuideCodingBasicsJSNI#calling
]


@com.google.gwt.smartpark.client.map.SmartPark::callFacebookAPI(Ljava/lang/String;Ljava/lang/
 String;)(facebookUrl);


You're calling the instance method without a receiver object.  You either
need to change the instance method into a static method, or add a receiver
object like foo.@[...](facebookUrl);  See
https://developers.google.com/web-toolkit/doc/latest/DevGuideCodingBasicsJSNI#methods-fields

Re: GWT Native Method Warning

2012-11-19 Thread Colin Alworth 
In addition to matthew's comment, you are invoking a method that apparently 
has two arguments

callFacebookAPI(Ljava/lang/String;Ljava/lang/String;)


with only one:

(facebookUrl)


Delete one of the two Ljava/lang/String; parts on the method invocation so 
you actually point to your method 

callFacebookAPI(String url)

correctly.
