I think your issue is the use of 'this' inside the eventlistener. At that
point, 'this' might not refer to what you think it does. I suggest creating
a variable of 'this' prior to the eventlistener code and use the variable
inside the function. That should clear up any ambiguity it might have.

Well, I tried your suggestion, it returns valid Element, but now I got
another
problem. I did this:
layout.addEventListener('appear', function() {
count = 300;
for(var i = 0; i < count; i++) {
var id = 'p' + i;
this.debug(id);
var element = document.getElementById(id);
this.debug(i + ' = ' + element);
if(element == null) continue;
for(var j = 0, list = this.controls[i], len = list.length; j <
len; j++) {
this.debug('c = ' + list[j].getElement());
element.appendChild(list[j].getElement());
}
}
qx.ui.core.Widget.flushGlobalQueues();
}, this);
And now list[j].getElement() returns null... Actually, is there a way to
generate the elemnt of widget inplace? I thought that flushGlobalQueues
should help? I even added:
qx.ui.core.Widget.addToGlobalWidgetQueue(text);
qx.ui.core.Widget.addToGlobalElementQueue(text);
But nothing helps.
Thanks,
