I am using a Tree component to hold a very large dataset. So
instead of loading the whole tree view at once, I only load the
first level and make webservice calls every time the user opens a
node using the itemOpen event handler. My only problem is that the
data shows but the scrollbar does not appear. When I close said
folder, and reopen, then the scrollbar appears.
How should I notify the Tree component that the data has
changed and that it should update the scrollbar. I dont want to use
ItemRenderer if I dont have to.
