Primefaces< p:ajax update =“" @ all" />不起作用 [英] Primefaces <p:ajax update="@all" /> doesn't work
问题描述
使用p:ajax更新属性元素时出现问题.当我在代码<p:ajax update="@all" />中使用时，我会得到javax.el.PropertyNotFoundException.当我使用<f:ajax render="@all" />时，我什么也没得到.我虽然那thouse标签几乎是相同的.谁能解释发生了什么事?
I've got a problem with using p:ajax update atribute element. When I use in my code <p:ajax update="@all" /> then I am getting javax.el.PropertyNotFoundException. When I use <f:ajax render="@all" /> I don't get any. I though that thouse tags are nearly same. Can anyone explain whats happening?
我正在使用mojjara实现，primefaces 3.5和Liferay jsf portlet桥.
I am using mojjara implementation, primefaces 3.5 and Liferay jsf portlet bridge.

两个按钮:
<p:commandButton value="not working" action="#{enrollmentManagementBean.cancelEnrollment}">
<p:ajax update="@all" />
</p:commandButton>
<h:commandButton value="working" action="#{enrollmentManagementBean.cancelEnrollment}">
<f:ajax render="@all" />
</h:commandButton>
推荐答案
OptimusPrime(Primefaces的主要开发者)指出update="@all"是一个坏主意，primefaces并非通过设计实现
OptimusPrime (main developer of Primefaces) states that update="@all" is a bad idea and primefaces does not implement it by design link to forum post.
为了解决该问题，我要做的就是依靠javascript刷新页面.只需将其放在按钮的oncomplete属性中即可.
What I do in order to get around the problem is rely on page refresh from javascript. Just put it in the oncomplete attribute of the button.
oncomplete="window.location.replace(window.location.href);"
我相信，如果您仍然遇到问题，或者可以在此作为将来的参考，这应该可以解决您的问题.
I believe this should solve your problem if you still have it, or be here for future reference.
