Re: JsInterop Shared Model + REST API

Paul,

If I go with T Broyer's suggestion of making User extend JavaScriptObject then would interop-utils be able to handle an array property User[] users within User for deserialization?

I'm trying to work around the issue of having a list deserialized as its correct type.  Ultimately I'd like to get my User[] back in browser JavaScript and be able to do
var users = ...deserialized User[]
users[0].getValue();

where getValue() is a @JsMethod

I'm realizing now that I can't do that unless @JsType(isNative = false because overlay methods can't be accessed from JavaScript.  Doing that causes a casting issue when using gwt.interop.utils.client.JSON to parse my incoming JSON string.

gwt-interop-utils shows one way of doing it. This assumes you are OK using intermediate collection types.

I'm trying to create a shared model in my GWT 2.8.2 application that I can use both at the server and in GWT client code.

My research/Google Fu tells me that this might be possible with JsInterop but since I'm new to JsInterop I'm just not sure.

I've done some experiments but I've run into a couple of issues with the biggest being that I can't have my model accessor methods if I make the model native.  The compiler tells me that they have to be native or abstract.

What I'd like to do with my model is:

@JsType

public class User {

    private double id;

    private String code;

    private String name;

    @JsConstructor

    public User() {

    }

    @JsIgnore

    public User(double id, String code, String name) {

        this();

        this.id = id;

        this.code = code;

        this.name = name;

    }

    ...

    @JsProperty

    public double getId() {

        return id;

    }

    @JsProperty

    public double setId(double id) {

        this.id = id;

    }

    ...

}

Then in my GWT application I'd like to do this:

    public class JsTypes {

        public static native <T> T getJsTypeObject(JavaScriptObject result)/*-{

            return result;

        }-*/;

    }

    //called after REST response from server

    private void onCallback(String json) {

Console.log("JSON:" + json);

JavaScriptObject result = JsonUtils.safeEval(json);

User user = JsTypes.getJsTypeObject(result);

        ...

        //do something with user

   }

Any ideas or suggestions would be greatly appreciated.
