&我想将其填充在ajaxbutton提交上.
但我收到此错误:

I created List view which contain 2 textboxes
& i want to fill those on ajaxbutton submit.
but I am getting this error:

组件com.cerebrum.pages.ShowCalculator $ ShowCalculatorForm $ 2具有 已添加到目标.此组件是转发器，不能为 通过ajax直接重绘.而是添加其父项或其他项 标记容器位于层次结构中较高的位置.

Component com.cerebrum.pages.ShowCalculator$ShowCalculatorForm$2 has been added to the target. This component is a repeater and cannot be repainted via ajax directly. Instead add its parent or another markup container higher in the hierarchy.

推荐答案

您应该使用WebMarkupContainer包围列表视图，并将此标记容器添加到请求目标.

You should surround your list view with a WebMarkupContainer and add this markup container to the request target.

html代码:

<div wicket:id="wmc">
    ...
    put your list view here
    ...
</div>

java代码

final WebMarkupContainer wmc = new WebMarkupContainer("wmc");
add(wmc);
ListView yourListView = ...
// init your list view here
wmc.add(yourListView);

SubmitButton yourButton = new SubmitButton("yourButton") {
    @Override
    public void onSubmit(AjaxRequestTarget target) {
        target.add(wmc);
    }
}
add(yourButton);
