I see it is a bit ugly, but oh well... this is how it works now.
in YourComponent#renderHead():
AtmosphereBehavior atmo =
getPage().getBehaviors(AtmosphereBehavior.class).get(0);
CharSequence callbackUrl = atmo.getCallbackUrl();
headerResponse.render(OnDomReadyHeaderItem.forScript("Wicket.Ajax.get({u:
"+callbackUrl+"})"));
You may need to use some flag to make sure this happens once per page
instance. Otherwise every re-render of such component will initialize a new
web socket connection (or whatever fallback you may use)
