Hi Dave,
it seems to me this is a general problem, because the
qx.ui.core.queue.Manager use in the qx 1.0 version a try/catch statement
which makes the queue robust. But this could brake the stack trace.
Please apply my attached patch to the __executeAndRescheduleOnError
method from the qx.ui.core.queue.Manager. I hope this solve you problem
I also opened a bug report, that the try/catch should only be done in
the build version.

Cheers,
Chris

I've been using the free Microsoft debugger called Visual Web Developer 2008
for a while now. It's great: when something bad happens you get a nice stack
to look at and an immediate window where you can evaluate expressions. In
other words, a real debugger, even in IE.
However, since I upgraded to qooxdoo 1.0, I'm finding that many stack traces
are bogus. If I refer to a nonexistent property -- due to a typo for example
-- then I get an alert box in the debugger saying something sensible like
"object does not support this property or method", but when I break and look
at the stack trace, it's always the same: it starts with a "mouseup" event
handler and ends up in some mystery function with these locals:
callback: {...}
finallyCode: {...}
self: {Class qx.ui.core.queue.Manager}
e: {Object does not support this property or method}
and the debugger shows me some totally unrelated lines of code in the source
view.
This happens with both the 2008 and the 2010 Beta 2 versions.
QooxDoo gods, any clues what's hijacking my stack when exceptions occur?
This makes debugging typos take about 100 times longer.
Dave
