I ran into Martin Wittemann's advice on using the delegate's bindItem
method so my code now looks like this:
var controller = new qx.data.controller.Tree(null, tree,
"contents", "name");
controller.setDelegate({
bindItem : function(controller, item, id) {
controller.bindProperty("name", "label", null, item, id);
controller.bindProperty("contents.length", "appearance", {
converter : function(data) {
return data > 0 ?
"tree-folder" : "tree-file";
}
}, item, id);
}
});
controller.setModel(model);
Everything works! Thanks!
