in short: since IE 11 and chrome as well as FF the browsers dont fire the DOMContentLoaded of scripts the way one would expect. This happens as the browsers branch multiple threads that each thread put together execution groups of orders leading to inline-JS getting executed and events on these fired without the knowledge of other JS resources as long as these are defered and / or / asnyc'd
Even worse, an app that may work well in local mode may break in production as network timing as well as client CPU count (influences thread) and speed of CPU and or GPU (yep... ) may change the timings the event DOMContentLoaded gets fired; even JQuery guys are plagued by this and have no real solution to it now IMHO https://github.com/jquery/jquery/issues/3271 I think we can get a real working one for wicket but had no time yet to try it out; Idea is to create the wicket object in the head at first inline script before any JS resources (defered or not) so that the page itself cant break because of this ----- Ursprüngliche Mail ----- > Von: "Andrea Del Bene" <an.delb...@gmail.com> > An: dev@wicket.apache.org > Gesendet: Donnerstag, 15.
