組件是一箇中繼器，不能通過ajax直接重新繪製

Question

我創建了包含2個文本框的列表視圖
&我想填補那些關於ajaxbutton提交。
但我得到這個錯誤：

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.

Answer 1

你應該圍繞你的列表視圖與WebMarkupContainer和這個標記容器中，加入到請求目標。

的html代碼：

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

Java代碼

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);
