I had the same issue as we needed a splash screen for our mobile
applications. What helps in my case was to just do this before loading
the "real" script:
window.qx = {};
qx.$$domReady = true;
I am not sure why this happens. Somehow the init system in qooxdoo
seems to be to modeled to one specific use case.
Not sure if it wouldn't be better when qooxdoo directly offers some
kind of splash screen feature in the future. It's not a too uncommon
need IMHO.
Cheers,
Sebastian
