What type is the component state?

[joblini]

He he good question, for V3.2.2 it is:

     protected DataComponentState componentState;
//     protected TreeState componentState;

[joblini]

import org.ajax4jsf.model.DataComponentState;

@Name("treeController")
@Scope(ScopeType.CONVERSATION)
public class TreeController 
{
        protected DataComponentState componentState;
//      protected TreeState componentState;

        public DataComponentState getComponentState() {
            return componentState; 
    }
        public void setComponentState(DataComponentState componentState) {
            this.componentState = componentState;
    }
}

Two things:

1)  I had to deploy the Richfaces jars in the .ear instead of the .war

2)  All the state saving is done by Richfaces in calls to getComponentState, which returns a reference to the ComponentState object.  setComponentState is only called once, during initialization.  This was a source of confusion to me while debugging.

Sadly, right now, it is impossible to control the expanded/collapsed state of the tree nodes from the bean model (but if could please vote for RF-4129 I'll be really nice of you)

You can do this in Richfaces V3.2.2 using the adviseNodeOpened attribute.  See example here
