Re: Refreshing a celltree

I have the same problems. The CellTree and TreeNode API are just
*weird* to me. For instance if you want to open a node, you need to do
it through teh parent, etc... There are methods available for getting
all this straight, but they are in the class CellTreeNodeView, which
is just not available, again I don't understand why. All we need is
this class.
