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;
}
}
