Hi T.,
first things first: Thanks a lot for your help.
I played around a little bit this morning. So these are the facts:
1. This issue appears only within a source version of the app
2. This issue came with Qooxdoo 1.6 (I migrated the affected app back to 1.5
and didn´t see any issues like that)
3. The workaround you proposed is the right one: Just add "require" : {
"qx.log.appender.Console" : ["qx.ui.core.Widget"] } to the source-script
build-job configuration
I wish I could publish a demo of that issue with our affected app, but I´m not
allowed to do anything like that because of non-disclosure constraints which
are very tight. But be sure...I am working on a permission to publish our apps
in terms of screenshots and a short description for your real life examples.
I´m afraid it will take some time...but some day...maybe..:-)
So...this is the bug report: http://bugzilla.qooxdoo.org/show_bug.cgi?id=5988
Once again: Thanks for your help !
Cheers,
Rob.

I'm surprised to hear that an undefined class could be a tiny issue, and that
the app continues to load!?

Indeed. I've looked through your stack trace, and I think you hit one of those
hard-to-track load dependencies. Those can go undetected for a long time, if
all classes "fall into place" due to other sorting constraints.
Changes in the class set or, (like here), in the sorting mechanics of the
generator can unveil the issue for a concrete app.
I don't think you will get much of a better answer anytime soon :-), so I
suggest you'll open a bug for it. If you can reproduce the issue in a largely
stripped-down app which you could attach, that would be awesome.
But in any case include your stack trace, and my answer here.
As a work-around, what you could do meanwhile is to explicitly require
qx.ui.core.Widget in a suitable place, e.g. in your config.json. For your build
jobs ("source", "build-script") you could add the following entry
"require" : { "qx.log.appender.Console" : ["qx.ui.core.Widget"] }
Maybe you have to play a bit with the class that is the key
(qx.log.appender.Console here), looking along your stack trace.
Best,
T.
