so in it's simplest form my page would look like this:
final MarkupContainer anotherComponent = add(new
Label("anotherComponent", "Updating should be pushed"));
anotherComponent.add(
new WebSocketBehavior() {
@Override
protected void onPush(WebSocketRequestHandler handler,
IWebSocketPushMessage message) {
super.onPush(handler, message);
handler.add(anotherComponent);
}
});
}
And will get anotherComponent refreshed with every WebsocketPushes..
It would be nice if there were a simple filter or way to determine if
the websocket push were relevant for the actually push..
The current implementation does feel a little lowlevel..
