Jsf 2，在dataTable中顯示驗證消息

我有一個問題，顯示由嵌套在dataTable中的UI組件觸發的驗證錯誤，它是。Jsf 2，在dataTable中顯示驗證消息

這裏是xhtml頁面，其中包含一個帶有靜態上部的表單，其中可以輸入地址。

它下面顯示訂單項目，用戶可以輸入他們想要訂購的物品數量。這些項目正在從數據庫表中檢索並顯示在dataTable中。

驗證表單的地址部分是完美的。不被顯示只爲形式的這部分消息：

<h:dataTable id="items" 
        styleClass="listing_large" 
        value="#{supply.supplyItems}" 
        headerClass="heading" 
        var="item"> 
        <h:column> 
         <f:facet name="header"> 
          #{msg['supplies.id']} 
         </f:facet> 
         <h:outputText value="#{item.supply_id}" /> 
        </h:column> 
        <h:column> 
         <f:facet name="header"> 
          #{msg['supplies.amount']} 
         </f:facet> 
         <h:inputText value="#{item.amount}" id="amount" styleClass="text" size="3" maxlength="3" style="width:50px"/> 
        </h:column> 
        <h:column> 
         <f:facet name="header"> 
          #{msg['supplies.description']} 
         </f:facet> 
         <h:outputText value="#{item.description}" /> 
        </h:column> 
       </h:dataTable>

驗證正在通過BeanValidation進行：

public class SupplyItem implements Serializable { 

private static final long serialVersionUID = 1L; 

@Id 
private long supply_id; 

private String description; 
private int orderNo; 

@Transient 
@Max(value=200) 
private int amount; 

/* 
* constructor 
*/ 
public SupplyItem() { 
    super(); 
} 

public long getSupply_id() { 
    return supply_id; 
} 

public void setSupply_id(long supply_id) { 
    this.supply_id = supply_id; 
} 

public String getDescription() { 
    return description; 
} 

public void setDescription(String description) { 
    this.description = description; 
} 

public int getOrderNo() { 
    return orderNo; 
} 

public void setOrderNo(int orderNo) { 
    this.orderNo = orderNo; 
} 

public int getAmount() { 
    return amount; 
} 

public void setAmount(int amount) { 
    this.amount = amount; 
}

}

它得到實際被驗證，但是消息未被顯示...

嘗試將輸入字段的ID動態設置爲 h：「=」的消息無效，通過h：messages globalOnly =「true」顯示。

任何幫助將高度讚賞。

您還沒有爲數據表中的任何位置的輸入字段設置<h:message>。你需要把一個

<h:message for="amount" />

在數據表中的某個地方準確地在那裏你想要顯示它們。

<h:messages globalOnly="true">只顯示帶有null客戶端ID的消息，因此對於具有非null客戶端ID的消息肯定不會起作用。您需要刪除globalOnly="true"才能顯示未在其他地方顯示的消息。
