You could also write it like this
// Return the whole JSON array, as is
private final native JsArray<Customer> getCustomers() /*-{
return new Array();
}-*/;
That way, the json structure doesn't have to be in your html.
Next, you could write an set method like this -
public final native void set(int i, E e) /*-{this[i] = e;}-*/;
So, now you can create and add elements to your JsArray entirely from Java
code.
