First, why not just use the open and close methods of each folder
instance.
What i don't like about the open and close methods is that they don't
work properly. Just put the code
te1.open();
te1.close();
at the end of the javascript code in "Tree_1.html". The folder "Desktop"
opens - but doesn't close again.
I don't know what your application requirements are, but it seems not to
be useful to open and directly close the same folder. (In this example
this is a problem with the display queue I think. You should do a
QxWidget.flushGlobalQueues between them to fix this.)
Normally you want to close or open folder structures on user reactions.
I don't think there is any problem with qooxdoo.
I think the best would be, if you explain more detailed what your needs are.

Second, you can save any information you like to an javascript
instance. Just do something like:
myTreeFolder._someInfo = "foo";
Also there is a nice qooxdoo interface for this type of data:
myTreeFolder.setUserData("someInfo", "foo");
alert(myTreeFolder.getUserData ("someInfo"));
Hope this helps.
This bit helped - its appreciated.
