我正在将应用程序从旧版本的检票口迁移到检票口 8。某些页面工作正常(登录等简单页面)。这些页面不使用扩展机制。 当我访问具有该机制的页面时，它不起作用。我不知道这是否是一个错误，但我尝试了所有方法，但找不到解决方案。 我正在使用检票口8.0.0-M5(我知道这不是一个稳定的版本)。有人有同样的问题吗？ 这是我的代码：
WerklijstPageXXX.html
<html xmlns:wicket>
<body>
<wicket:extend>
<div wicket:id="panelXXX"></div>
</wicket:extend>
</body>
WerklijstPanelXXX.html
<wicket:head xmlns:wicket>
</wicket:head>
<wicket:panel xmlns:wicket>
<div wicket:id="filter">
<div wicket:id="label"></div>
</div>
</wicket:panel>
WerklijstPageXXX.java
public class WerklijstPageXXX extends BasePage {
private WerklijstPanelXXX werklijstPanel;
public WerklijstPageXXX() {
werklijstPanel = new WerklijstPanelXXX("panelXXX"){};
add(werklijstPanel);
}
@Override
public Panel getContextPanel(String id)
{
return werklijstPanel.getWerklijstFilterPanel();
}
WerklijstPanelXXX.java
public abstract class WerklijstPanelXXX extends Panel {
private static final Logger LOG = LoggerFactory
.getLogger(WerklijstPanelXXX.class);
private Panel filterPanel;
public WerklijstPanelXXX(String id) {
super(id);
WebMarkupContainer upperPanel = new WebMarkupContainer("filter");
filterPanel = new Panel("filterPanel") {
};
add(upperPanel);
upperPanel.add(new Label("label"));
}
public Panel getWerklijstFilterPanel() {
return filterPanel;
}
编辑： 基本页面.html(其中的一部分)
<div id="body" class="body">
<div id="aside" class="aside">
<div wicket:id="contextPanel"></div>
</div>
<div id="content" class="content">
<div class="padding">
<wicket:child></wicket:child>
</div>
</div>
</div>
基本页面.java
@Override
protected void onInitialize() {
super.onInitialize();
add(getContextPanel("contextPanel"));
addTabMenu();
addMenu();
addPatientBar();
}
错误：
根源：
org.apache.wicket.WicketRuntimeException：下面的组件无法呈现。可能的原因可能是： 1)您在代码中添加了一个组件，但忘记在标记中引用它(因此该组件将永远不会呈现)， 2) 如果您的组件已添加到父容器中，请确保子容器的标记将它们包含在 中。

Java 和 HTML 组件树应该匹配。
您的 HTML 状态为：<div wicket:id="*contextPanel*"></div>，但您的 Java 代码返回一个 id 为filterPanel的面板。
public WerklijstPageXXX() {
werklijstPanel = new WerklijstPanelXXX("panelXXX"){};
add(werklijstPanel);
}
@Override
public Panel getContextPanel(String id) // HERE id is ignored
{
return werklijstPanel.getWerklijstFilterPanel(); // This returns a panel with id `filterPanel`
}
