Below this I have "get" and "set" methods.

My JSF code for <rich:tree> component looks like this:

You can. I do. However, you can't simply point the tree at the data, you need a treemodel wrapper just like you need a databtable model wrapper. They both help maintain the UI-specific context.

Check the RichFaces docs. In recent releases, they added a way to easily wrap things such as domain model objects so you don't actually need to construct a tree-specific data model.
