h：inputSecret redisplay =「false」required =「false」><s：validateEquality：確認字段要麼不需要檢查

Question

我使用seam 2.2.0.GA. 我的密碼/確認字段有redisplay =「false」，所以當前密碼不在html中。 validateEquality在確認字段中。

我想要以下行爲：當我創建一個新的實體時，應該都需要密碼/確認字段。當我編輯一個實體時，不應該要求這兩個字段，但在任何情況下都應該檢查相等性。爲此我有h：inputSecret required =「＃{required}」並計算param「required」。

有是兩個問題：

1）S：validateEquality有「需要」太屬性，但它看起來馬車：如果我硬編碼真的還是假的，它工作正常，但如果我使用所需= 「＃{required}」並且在對話期間這個參數改變了，驗證器仍然表現得好像param沒有改變。

2）s：validateEquality required =「false」如果confirm字段爲空，則不檢查相等性。

Answer 1

問題1：

下面的代碼將您的 「要求」 現場靜，我相信：

<ui:param name="required" value="#{sandboxBean.required}"/> 

問題2：

http://seamframework.org/Community/CustomValidatorUsingTwoFields

使用標有相應的註釋自定義驗證，然後你可以自定義驗證調用。

@Validator 
public class PasswordValidator implements javax.faces.validator.Validator, Serializable{ 
... 
throw new ValidatorException(new FacesMessage("Passwords do not match.")); 

Answer 2

public class PasswordConverter 
    implements Converter 
{ 
    public static String DONT = "__dontchange__"; 

    public Object getAsObject(FacesContext context, UIComponent component, String value) 
    { 
     if (DONT.equals(value) && component instanceof UIOutput) { 
      return ((UIOutput)component).getValue(); 
     } else { 
      return value; 
     } 
    } 

    public String getAsString(FacesContext context, UIComponent component, Object value) 
    { 
     if (value instanceof String && component instanceof UIOutput && ((String)value).length() > 0) { 
      return DONT; 
     } else if (value == null) { 
       return null; 
     } else { 
      return value.toString(); 
     } 
    } 

}
