Hey,

You'll have to call attachThread() in the new thread.

Also, calling attachThread() manually (and not having it as a consequence of grabbing the update lock) is a tell-tale signal of interacting with the widget tree without holding the lock.

final WApplication theApp = WApplication.getInstance();
new Thread(()->{
  theApp.attachThread(true);
  //change something
  // actually, to change something you should have grabbed theApp's updatelock.
}).start();

Wim.
