Good question.  I'll take a look.  I have heard of others having a similar
problem, so there may be something that we are doing in LdbBrowse (and others
do in their apps) that causes it.  I'll let you know.

Well the currently used event (TreeOpenWhileEmpty) is *not* fired at every
open, since only on the first open is that branch empty.  The event handler
for TreeOpenWhileEmpty adds children to that branch, so if you close it and
re-open it (without deleting its contents at some intervening time), the
TreeOpenWithContent event will fire, not the TreeOpenWhileEmpty event.

Uggh!  You're trying to do this without any code to reference?  That's fairly
painful!  You'll definitely want to be looking at all of the sample programs.
Sorry I neglected to point you to these earlier!  Look in:

  webapps/qooxdoo*.sdk/frontend/demo/source/html/example
  webapps/qooxdoo*.sdk/frontend/demo/source/html/test

You should find just about everything you need in the example directory.
There are examples, there, for just about all widgets, and some combined ones.
The test directory contains some obscure stuff, but if you're not getting what
you need from the examples for the widget, you may well find something useful
in the test directory.

Note that the examples still use the outdated application style, with html and
javascript mixed in the same file.  Correcting that is planned for Real Soon
Now (tm), I understand.  That should not at all effect you using them as
reference, however.

Cheers,
