Expanding the TreeView bean

Hello,
Regarding the DBTreeView, i am expecting that this method:
.setNodeLevelVisible(100,true)
called on the bean, would expand the tree to the fullest, if it has less than 100 nodes. But sometimes, a tree which has less than 100 nodes is fully collapsed instead of being fully expanded.
Is there a reason why it would behave like this?
