@EventListener＆IRequestCycle.getResponseBuilder.updateComponent未更新組件

Question

我在應用程序中遇到問題，我正在嘗試的是當有人將表單上的字段shopStatus更改爲Pass，我希望它更新我的字段shopApprovalDate爲必填項。我現在用的是下面的事件監聽器此

@EventListener(targets="shopStatus", events="onchange") 
public void onLicenseStatusChange(IRequestCycle cycle) { 
    cycle.getResponseBuilder().updateComponent("shopStatus"); 
    cycle.getResponseBuilder().updateComponent("shopApprovalDateRequired"); 
    cycle.getResponseBuilder().updateComponent("shopApprovalDate"); 

} 

這是我使用這個

<td valign="center" align="left" class="rightTD" height="30" > 
     <span jwcid="@If" condition="ognl:company.shopStatus == @valueobject.ShopStatus@Pass" renderTag="literal:false"> 
      <input jwcid="shopApprovalDateRequired@CustomDatePicker" disabled="ognl:disabled || isShopApprovalDateDisabled()" 
      value="ognl:company.shopApprovalDate" displayName="message:company.shopApprovalDate" validators="validators:maxDateToday,required" /> 
     </span> 
     <span jwcid="@Else" renderTag="literal:false"> 
      <input jwcid="shopApprovalDate@CustomDatePicker" disabled="ognl:disabled || isShopApprovalDateDisabled()" 
      value="ognl:company.shopApprovalDate" displayName="message:company.shopApprovalDate" validators="validators:maxDateToday" /> 
     </span> 
     </td> 

的事情是，如果我改變shopStatus到Pass沒有任何反應的HTML，但如果我保存頁面並重新加載頁面，然後shopApprovalDate被設置爲強制性的，所以html代碼正在工作，它就像@EventListener未更新shopApprovalDate當shopStatus被更改！我已經通過代碼調試，它是擊中聽衆，但沒有發生

有沒有人有任何想法呢？

這是因爲你需要如果添加了調用的東西，調用@IF @Else而不是實際的組件本身

更新的@If @Else外，並呼籲，在事件監聽器此應工作，然後像這樣

的<div>

<div jwcid="licenceAuthRequiredDiv@Any"> 
<td valign="center" align="left" class="rightTD" height="30" > 
    <span jwcid="@If" condition="ognl:company.shopStatus == @valueobject.ShopStatus@Pass" renderTag="literal:false"> 
     <input jwcid="shopApprovalDateRequired@CustomDatePicker" disabled="ognl:disabled || isShopApprovalDateDisabled()" 
     value="ognl:company.shopApprovalDate" displayName="message:company.shopApprovalDate" validators="validators:maxDateToday,required" /> 
    </span> 
    <span jwcid="@Else" renderTag="literal:false"> 
     <input jwcid="shopApprovalDate@CustomDatePicker" disabled="ognl:disabled || isShopApprovalDateDisabled()" 
     value="ognl:company.shopApprovalDate" displayName="message:company.shopApprovalDate" validators="validators:maxDateToday" /> 
    </span> 
    </td> 
</div> 

事件監聽器

@EventListener(targets="licensingStatus", events="onchange") 
public void onLicenseStatusChange(IRequestCycle cycle){ 
    cycle.getResponseBuilder().updateComponent("licenceAuthRequiredDiv"); 
}
