Somewhere in the doco I found that you *sometimes* need to call validateNow() or the visual represntation may not be what you desire. So I now *a;ways* call validateNow() and all is well. I am still looking for an answer to how to use the default TreeDataDescriptor to get the set of first children (those with no parent) for a tree with no root item.
