TreeData is a UIComponent
that supports binding data stored in a tree represented
by a TreeNode
instance. During iterative processing over the tree nodes in the
data model, the object for the current node is exposed as a request attribute under the key
specified by the var
property. Renderer
s of this component should use
the appropriate Facet
to assist in rendering.
