Re: JsInterop Array

I had a similar problem with DataTables requiring a String[] argument. The one generated from java had some hidden fields that DataTables choke on. I ended up creating a JsString type that casts from/to String, but at the time I didn't know or didn't exist the gwt-interop-utils.

In your case however I would suggest the following:

*** NOTE:  int and int[] are not represented in javascript *** and you may have a problem during casting in/out. I would suggest using double if/when you hit the problems. Traceback and browser's debugger is invaluable.

@JsType(isNative = true, namespace = JsPackage.GLOBAL, name = "Object")

public class NodeSet {
  public int id;
  public int x;   <-- conside use of double
  public int y;
  public int[] nodes;

  @JsOverlay
  public static NodeSet create(int id, int x, int y, int[] nodes) {
      final NodeSet ns = new NodeSet();
      ns.id = id;
      ns.x = x;
      ns.y = y;
      ns.nodes = nodes;
      return ns;
  }
}

Hello guys, so I'm getting crazy with this.

I need to inject a java array inside a javascript library.

The problem is that the Js library will iterate over an integer array, and if the element is not an integer it exits the function.

When I create the integer array and pass it to plain javascript array, for some reason it carries garbage inside, I already tried everything with no success.

So this is my java nodeset (https://pastebin.com/AdJqj80p)

I'm using the gwt-interop-utils -> https://github.com/GWTReact/gwt-interop-utils/blob/master/src/gwt/interop/utils/client/plainobjects/JsPlainObj.java

And when I inspect the javascript object in the browser you can see it has lots of garbage, and I cant clean it. See the nodes array I have (_clazz_0_g$,__elementTypeCategory$,_elementTypeId$"......).

And when I do the same with Js I don't have this garbage (obvious).

I already used the JsArray and everything, but no luck =/.

Do you have any Idea how to have a plain javascript array with jsInterop?

Thanks a lot.
