How can force rich:tree to show a node handle(i.e. not to treat the node as a leaf) even if this node doesn't have any children for the time nodes are composed on the current level. I want to implement lazy loading of nodes, and load nodes only in the particular level at once. Children nodes beneath the current one will be loaded and added to the model on the expand event handling.
Please, give me a clue how to realize this functionality.
Many thanks in advance, Alexey
Implement org.richfaces.model.TreeNode.isLeaf() to return false for nodes not yet loaded.
