错误

/index.xhtml @xxxxx父级不是EditableValueHolder的实例：javax.faces.component.html.HtmlPanelGrid@5790b5bb

我已经检查了类似的问题，但他们没有帮助。

IDE：NetBeans

服务器：GlassFish

试试这个：

<h:inputText id="isim" value="#{degiskenBean.eposta}" required="true" validatorMessage="Geçersiz E-posta"  requiredMessage="E-Posta Alanı Zorunludur" >
   <f:validateRegex pattern="^([_a-zA-Z0-9-]+(\\.[_a-zA-Z0-9-]+)*@[a-zA-Z0-9-]+(\\.[a-zA-Z0-9-]+)*(\\.[a-zA-Z]{1,6}))?$"/>
</h:inputText>
<h:message for="eposta" />

f:validateRegex应位于h:inputText代码

中

<f：validateregex>父级不是EditableValueHolder的实例：javax.faces.component.html.HtmlPanelGrid
