Hi,
as you didn't give very detailed information about your circumstances
(which version of qooxdoo) and the exact kind of error you're getting, I
can only assume, what's not working.

QxTree.prototype.add.call(this.folder); // folders never show

I assume this is your problematic area.
Why are you referencing the "folder" variable by "this.folder" here,
while declaring it as a local variable via "var"?
And why don't you call "add()" on your instance of QxTree but instead
via the prototype?
If you want to keep this coding style and use a closure as event
listener, then do something like
<code>
var currentTree = this;
</code>
before adding the eventlistener, and then make the call to add() like this:
<code>
currentTree.add(folder);
</code>
But I recommend refactoring the event listener into an instance method
of your tree class and adding the event listener like this:
<code>
this._ajax.addEventListener('complete', this.<yourMethodName>, this);
</code>
If this doesn't help, or I miss your point ;) then please post more
details of your case, along with exact error messages.
Cheers
Benjamin
