问题描述

我在 h:form

<h:panelGrid id="captchaGrid">
    <p:captcha id="captcha" label="Captcha" required="true"
        requiredMessage="required"
        validatorMessage="...">
    </p:captcha>
    <p:message id="captchaMessage" for="captcha" />
</h:panelGrid>

<p:commandButton id="submitButton" value="save"
    actionListener="#{userBean.save}" update="captchaGrid"
    onstart="doSomething()"
    oncomplete="doSomethingElse(xhr, status, args)" icon="ui-icon-check">
</p:commandButton>

如果我正确输入验证码，这工作正常.但是，如果我输入了无效值，验证码组件就会消失.

This works fine if I enter the captcha correctly. However, if I enter an invalid value, the captcha component just disappears.

我尝试删除 update="captchaGrid" 属性.这一次，验证码没有消失.相反，它没有在视觉上刷新，而是(我猜)在内部刷新.因为正确输入这两个词仍然会产生验证错误.

I tried removing the update="captchaGrid" attribute. This time, the captcha didn't disappear. Instead, it didn't refresh visually but (I guess) internally. Because typing the two words correctly still generates a validation error.

此外；我不想使用 ajax="false".

更新:我也试过 oncomplete="Recaptcha.reload()".没用.有一个错误.但我不知道是我的代码还是 Primefaces 3.0 :)

Update: I also tried oncomplete="Recaptcha.reload()". Didn't work. There is a bug. But I don't know if it's my code or Primefaces 3.0 :)

更新 2: 正如 maple_shaft 指出的那样，事实证明这是 Primefaces/Recaptcha 的问题.所以我正在寻找你可能建议的任何肮脏的黑客.

Update 2: As maple_shaft pointed out, it turns out that this is a problem with Primefaces/Recaptcha. So I'm looking for any dirty hacks you might suggest.

感谢任何帮助.

推荐答案

您不会喜欢我的回答，但这不是错误.

You are not going to like my answer, but this is not a bug.

Primefaces 问题 1642 被标记为无法修复.

Primefaces Captcha 使用 Recaptcha，它不支持也不能支持 Ajax 刷新.您必须执行整页回发才能使该组件正常工作.请记住，这也会影响在需要 Ajax 刷新面板的组件(例如选项卡视图或向导组件)中使用验证码的能力.

The Primefaces Captcha utilizes Recaptcha, which does not and cannot support Ajax refresh. You must do a full page postback for this component to work properly. Keep in mind this also affects the ability to use the Captcha in components that require Ajax refresh of a panel, such as a Tab View or Wizard component.
