Yes, a label function should only build the label string, not do anything else, especially manipulate the visual elements of the control it is being used to render. A label function gets called for every visible node in the tree, which changes when you scroll, open a node, etc. No wonder you confused the poor tree!
What is the goal of that line?

Commenting the line: //expandTree(); fixes it. I don't use Tree but I would surmise you are double handling the expand functionality. From what I can see the tree component already implements expand and by adding your own you are causing the problem. Someone else who uses tree more extensively may have a better explanation. HTH.
