Before I post I already have a look to the demo and documentation, but I don't undertand the meaning of many tags like stateAdvisor. The documentation say is a "ValueBinding pointing at instance of class implementing org.richfaces.component.state.TreeStateAdvisor interface.", ok but what it does?
Is it necessary to sorround the the tag tree with the <h:form> tag?
I'd need a easy example with the minimun necessary.
TreeStateAdvisor is used to "advise" change to node state, e.g. expand it or select it.
Tree of client switch type does not need form, another switch types require it.
