I use extensions TreeTable and populating the all nodes is quite expensive. So I would like to display initially only first level of the nodes and keep the nodes with children collapsed. Only if they are getting expanded, I would populate the children of the currently expanded node. I have hard time figuring it out just from javadoc. Is there a way to do that for TreeTable or do I have to populate all tree nodes when I display the TreeTable even if the nodes with children are collapsed.
