我想使用自定义 JSF 验证器显示错误消息。

验证后，我没有呈现任何消息！

已编辑

我添加了更多 xHTML 代码，我有一个包含许多字段的弹出窗口和一个a4j:commandButton.

public void validate(FacesContext facesContext, UIComponent uIComponent, Object object) throws ValidatorException{
    String enteredValue = (String)object;
    if(enteredValue.contains(",")){
        enteredValue = enteredValue.replace(",", ".") ;

    boolean isANumber = false;

尝试将另一个字符串参数传递给 FacesMessage 构造函数，第二个字符串将显示在客户端。

FacesMessage msgErreur = new FacesMessage("La valeur n'est pas un nombre valide.", "validation error msg") ;
