Luke,
I'm not in the situation where I can oversee all of what you are
writing, but if you have reasonable concerns about some behaviours of
qooxdoo I strongly urge you to open a bug report. Just write the things
as you have found them, and attach any code that might reproduce the
issue. This will most likely result in a proper answer, sooner or later :).

Hi,
I would like to re-open this thread and add the results of my
investigations. Even if it is a quite old theme, it helped me most with
drag&drop on tree.
I am attaching the original file from Christian with changes that solves
most of the problems I have found in this thread.
In my case, I wanted to enable D&D only for items under the same parent
folders, but it is easy to change it, if somebody needs.
However, during testing I found probably buggy behavior of methods addBefore
and addAfter inside AbstractTreeItem.js.
addAfter() - works correctly only when adding after the last children, but
when adding after e.g. 2nd child from 5, the item is added after 3rd item
addBefore() - doesn't work correctly at all, not possible to add before the
last child and when adding before e.g. 3rd child from 5, the item is added
before 4th item (expected behavior of addAfter() method)

Christians Solution is the best I've seen so far ... Also I frequently get
uncaught exceptions like
"037866 qx.event.Registration.getManager(null) was called!" or "target is
null"
Agree with Phil. I had also this problem, and couldn't find out how to
prevent it or fix it (maybe only if(!target) return; :)). The error causes
qx.event.Manager.dispatchEvent(target, event), because the "target" argument
is somehow lost after the drag drop event model is completed.
As I didn't find any reported bug on addBefore/addAfter methods for tree, I
am not sure if it is considered as a bug. Anyway, it is possible to test the
mentioned problems with the attached file.
And I would really appreciate if there is some explanation or fix for the
qx.event.Manager.dispatchEvent() method.
Thanks and happy New Year,
Luke
