Java 使用ace:tabSet和ice:tree动态创建xhtml页面

我创建了一个动态页面，其中包含一些ace:tabPane，每个页面中都有一棵树 xhtml页面：

在页面后面有一个bean configProfilesBean，我在其中创建绑定在页面中的选项卡集，并动态创建一些ace:tabPane:

tabSet = new TabSet();
tabSet.getChildren().clear();
tabSet.setId("tabSetConfigProfiles");
tabSet.setClientSide(false);

for (FunzioneDTO f : funzioni) {                        
    tabSet.getChildren().add(createTabPane(f));         
}

方法

createTabPane（FunzioneDTO函数）

：

然后这是树模型的类：

public class TreeModel implements javax.swing.tree.TreeModel{

    private DefaultTreeModel model;
    private DefaultMutableTreeNode rootTreeNode;
    private FunzioneDTO function;    

    public TreeModel(FunzioneDTO function){

        this.function = function;      

        IceUserObject rootObject = new IceUserObject(getRootTreeNode());

        rootObject.setText("ROOT");         
        rootObject.setExpanded(true);

        getRootTreeNode().setUserObject(rootObject);

        if(function.getAzioni().size()>0){
            for(AzioneDTO a : function.getAzioni()){
                getRootTreeNode().add(addActionChildNode(a));
            }
        }
    }

    private DefaultMutableTreeNode addActionChildNode(AzioneDTO action){

        DefaultMutableTreeNode childAction = new DefaultMutableTreeNode();
        IceUserObject actionObject = new IceUserObject(childAction);
        actionObject.setText("A_"+action.getId());      
        actionObject.setLeaf(true);
        childAction.setUserObject(actionObject);

        return childAction;

    }

    public DefaultTreeModel getModel() {
        if(model == null){
            model =  new DefaultTreeModel(getRootTreeNode());   
        }
        return model;
    }

    public void setModel(DefaultTreeModel model) {
        this.model = model;
    }

    public DefaultMutableTreeNode getRootTreeNode() {
        if(rootTreeNode == null){
            rootTreeNode = new DefaultMutableTreeNode();
        }
        return rootTreeNode;
    }

    public void setRootTreeNode(DefaultMutableTreeNode rootTreeNode) {
        this.rootTreeNode = rootTreeNode;
    }

    public FunzioneDTO getFunction() {
        return function;
    }

    public void setFunction(FunzioneDTO function) {
        this.function = function;
    }

    @Override
    public Object getRoot() {

        return getModel().getRoot();
    }

    @Override
    public Object getChild(Object parent, int index) {

        return getModel().getChild(parent, index);
    }

    @Override
    public int getChildCount(Object parent) {



        return getModel().getChildCount(parent);

    }

    @Override
    public boolean isLeaf(Object node) {

        return getModel().isLeaf(node);
    }

    @Override
    public void valueForPathChanged(TreePath path, Object newValue) {

        getModel().valueForPathChanged(path, newValue);
    }

    @Override
    public int getIndexOfChild(Object parent, Object child) {

        return getModel().getIndexOfChild(parent, child);
    }

    @Override
    public void addTreeModelListener(TreeModelListener l) {

        getModel().addTreeModelListener(l);

    }

    @Override
    public void removeTreeModelListener(TreeModelListener l) {

        getModel().removeTreeModelListener(l);

    }
}

当我转到页面时，我有一个由nullpointerexception引起的stacktrace，我不知道如何解决：

有人知道怎么解决吗？

谢谢

在bean的初始化中，您在哪里调用

选项卡集

创建代码？但是如果我从选项卡窗格中删除树，我可以看到所有的tabPane都是空的。可能树中有一个元素是必需的，而您尚未初始化它。我认为您是对的，但我不知道是什么组件……首先尝试在设计时创建树组件，即创建一个基本的Facelet，向您展示树在页面中的位置。然后检查是否在代码中动态初始化了所有这些属性。我不是IceFaces的用户，所以我想我帮不了你更多。
