I am using GWT 2.8.0-SNAPSHOT, but the new annotations does not work for me.
I tried using @JsType(namespace = "acme", name = "MyJavaScriptObject"), as described in the new version of the JsInterop document, but apparently the namespace and name attributes are not there in the jar file. Same thing with the @JsExport and @JsNamespace, I currently have to use them or things stop working. My gwt-user-2.8.0-SNAPSHOT.jar, which contains the annotations, is from today. This is the pom I am using: https://github.com/bitwerk/jspoc/blob/master/pom.xml /Brian Den mandag den 26. oktober 2015 kl. 11.43.32 UTC+1 skrev Thomas Broyer: > > You may want to use GWT 2.8.0-SNAPSHOT and the new JsInterop annotations; > as your usecase maybe is just not supported with the "old" annotations. > > On Monday, October 26, 2015 at 11:10:28 AM UTC+1, Brian Pedersen wrote: >> >> I have a dispatch method, exposed through JsInterop, which can take >> various kinds of payloads. >> >> Once called from native javascript, I need to cast the payload, but this >> doesn't quite work as I would like it too. >> >> Here is a simplified example. >> >> *GWT:* >> @JsExport >> @JsType >> @JsNamespace("foo") >> public class Dispatcher { >> public String dispatch(String action, Payload payload){ >> if("action1".equals(action)) >> return dispatchWithCast(payload); >> return "Unknown action: " + action; >> } >> public String dispatchWithCast(Payload payload){ >> ConcretePayload w = (ConcretePayload) payload; >> return w.foo; >> } >> } >> >> @JsExport >> @JsType >> public class Payload {} >> >> @JsExport >> @JsType >> public class ConcretePayload extends Payload { >> public String foo; >> public int bar; >> } >> >> *Javascript:* >> var test = new foo.Dispatcher(); >> alert("Dispatch: " + test.dispatch("action1", {"foo": "a", "bar": 2})); >> // Uncaught java.lang.ClassCastException >> >> Everything works just fine if I replace the Payload type in the >> Dispatcher class with ConcretePayload, and removes the cast. >> >> I guess this this may be beyond the capabilities of the transpiler, I >> just need to figure out an alternative approach. >> >> Any ideas? >> >> (By the way, I am using the sso linker.) >> > -- You received this message because you are subscribed to the Google Groups "GWT Users" group.
