RichFaces TreeNode - невозможно передать в javax.swing.tree.TreeNode

Я пытаюсь использовать реализацию дерева RichFaces. Я подклассифицировал класс TreeNodeImpl - ниже мой суперкласс класса декоратора. Я получаю вышеуказанную ошибку. Конечно, я не реализует javax.swing.tree.TreeNode - Я реализую org.richfaces.model.TreeNodeRichFaces TreeNode - невозможно передать в javax.swing.tree.TreeNode

package com.base.view.tree; 

import org.richfaces.model.TreeNode; 
import org.richfaces.model.TreeNodeImpl; 

import com.iLearn.model.base.Typed; 

public abstract class TreeNodeDecorator<T extends Typed> extends TreeNodeImpl implements TreeNode { 

    public TreeNodeDecorator(T theData) { 
     super(); 
     setData(theData); 
    } 

    private T data; 
    public abstract String getDisplayString(); 
    public abstract boolean isLeaf(); 

    public T getData() { 
     return data; 
    } 

    public void setData(T theData) { 
     data = theData; 
    } 

    public String getType() { 
     return getData().getType(); 
    } 
}

Замечательная ... публикация, где вы получите эту ошибку, будет очень полезной (stacktrace) – Kukeltje

RF 4.5 добавлена модель дерева Swing для поддерживаемых моделей компонентов дерева. Видимо, что-то там не получилось. – BalusC

Я создал альтернативный суперкомпьютер декоратора, который реализует javax.swing.tree.TreeNode. Это позволяет избежать вышеуказанной ошибки, хотя я вынужден реализовать Enumerator (код в классе swing выглядит старым). Однако я не получаю выбранное событие. – Ramesh

Это похоже на ошибку в коде RichFaces, пока я не узнаю о разработчике RichFaces, который говорит иначе. Я перепроектировал дерево в PrimeFaces, и теперь он отлично работает.
