I couldn't reproduce the IntParser problem with following test:
@JsType(namespace = JsPackage.GLOBAL)
public static class IntParser {
public static int parseArray(String[] args) {
return Integer.parseInt(args[0]);
}
}
public void testStringArray() {
assertEquals(42, callIntParser());
}
private native int callIntParser() /*-{
return $wnd.IntParser.parseArray(["42"]);
}-*/;
Also in your earlier example, you are casting { qux: 42 } to Baz which will
fail because ({ qux: 42 } instanceof com.acme.Baz) is not true as { } is
instance of global Object. You can change Baz to point to that:
@JsType(isNative = true, name="Object", namespace=GLOBAL)
class Baz implements Foo {
public int qux;
}
