org.apache.wicket.markup.MarkupNotFoundException：找不到组件的标记：[TreeTableItem [Component id = 0]]

问题描述

将Wicket框架从6.x升级到8.x后，出现错误提示。在哪里更新了以下依赖关系，以将弃用的TreeTable代码保留在wicket 8.x中。

<dependency>
    <groupId>org.wicketstuff</groupId>
    <artifactId>wicket15-tree</artifactId>
    <version>8.0.0</version>
</dependency>

@SuppressWarnings({ "deprecation" })
private void myTreePage() {
    TreeTable myTestTree = new TreeTable("myTestTreeTable",new DefaultTreeModel(myTestRootNode),cols);
    statusImport();
    myTestTree.setRootLess(true);
    myTestTree.setoutputMarkupId(true);
    addOrReplace(myTestTree);
}

如我发现如果删除标签，则页面正在加载而没有任何错误。我认为这里的问题是标签位置或标签定义。

解决方法

将TreeTable类替换为TableTree类后，我解决了该异常。

请参考以下代码：

    private final DefaultMutableTreeNode rootNode = new DefaultMutableTreeNode("<root>");
DefaultTreeModel treeModel = new DefaultTreeModel(rootNode);

        ITreeProvider<DefaultMutableTreeNode> modelProvider = new TreeModelProvider<DefaultMutableTreeNode>(treeModel,false) {
            private static final long serialVersionUID = 1L;
            @Override
            public IModel<DefaultMutableTreeNode> model(DefaultMutableTreeNode object) {
                return Model.of(object);
            }
        };
        
        TableTree<DefaultMutableTreeNode,String> myTestTree = new TableTree<DefaultMutableTreeNode,String>("myTestTreeTable",createColumns(),modelProvider,Long.MAX_VALUE) {
            private static final long serialVersionUID = 1L;
            @Override
            protected Component newContentComponent(String id,IModel<DefaultMutableTreeNode> model) {
                //return new CheckedFolder<DefaultMutableTreeNode>(id,this,model);
                return new Folder<DefaultMutableTreeNode>(id,model);
            }
        };
        
        //myTestTree.getTable().addTopToolbar(new HeadersToolbar<>(myTestTree.getTable(),null));
        //myTestTree.getTable().addBottomToolbar(new NoRecordsToolbar(myTestTree.getTable()));
        myTestTree.setOutputMarkupId(true);
        myTestTree.add(new WindowsTheme());
        //myTestTree.setItemReuseStrategy(new ReuseIfModelsEqualStrategy());
        //myTestTree.getTable().add(AttributeModifier.replace("class","table table-striped table-condensed"));
        myTestTree.getTable().add(AttributeModifier.replace("style","width: 100%; background-color:white;"));
        addOrReplace(myTestTree);

树表日期显示完美，但表列标题的名称未显示在页面中。请参考列创建代码。

    private List<? extends IColumn<DefaultMutableTreeNode,String>> createColumns() {
    columns.add(new TreeColumn<>(new Model("Tree"),"obj.text"));
    columns.add(new PropertyColumn<>(new Model("FileStatus"),"FileStatus","obj.fileStatus"));
    columns.add(new PropertyColumn<>(new Model("StartDate"),"StartDate","obj.startDate"));
    columns.add(new PropertyColumn<>(new Model("LastDate"),"LastDate","obj.lastDate"));
    columns.add(new PropertyColumn<>(new Model("Count"),"Count","obj.count"));
    return columns;
}
