Hello Tobias,
I didn't figured out completely what your problem is, but let's give it a
try :)

Just a hint: better use the "getLabelObject()"-method here, instead of
accessing the LabelObject directly with "_labelObject".

You can assign user-data to each of your tree-folder and access this user-data
in your "changeSelection"-handler to change the content of your atom-widget
for each of your tree-folder.
myTreeFolderInstance.setUserData("KEY", "VALUE");
and in your "changeSelection" you can use
tree.getManager().addEventListener("changeSelection", function(e) {
var data = e.getData()[0].getUserData("KEY");
this.myAtom.setLabel(data);
}, this);
to access your user-data and set it as the atom's content.
All you have to do is to provide the data for each tree-folder which should be
shown in your atom widget.
I hope this points out a solution for your problem.
cheers,
Alex
