primefaces命令按钮更新不起作用

问题描述

我已将代码最小化，以更好地向您展示什么不起作用.

I have minimized my code to better show you what is not working.

<h:body>
<f:view>
    <h:form id="wbSelectForm">
        <p:commandButton id="viewWorkbenchButton" icon="ui-icon-show"
            title="View Workbench" update=":wbTestPanel"
            actionListener="#{WorkbenchControllerBean.test}">
        </p:commandButton>
    </h:form>

    <p:panel id="wbTestPanel">
            Test: Active Wb: #{WorkbenchControllerBean.number}
    </p:panel>
</f:view>
</h:body>

当我按下commandButton时，我希望'wbTestPanel'正在更新，但不会发生.我知道这是因为未调用WorkbenchControllerBean.getNumber().

When i press the commandButton, i would expect that 'wbTestPanel' is being updated, which does somehow NOT happen. I know that because WorkbenchControllerBean.getNumber() is not called.

我正在使用primefaces 3.5.我已经尝试过为'process'-attribute分配differend值，并将RequestContext.getCurrentInstance().update("wbTestPanel")放入WorkbenchControllerBean.test()-method.

I am using primefaces 3.5. I already tried differend values for 'process'-attribute as well as putting RequestContext.getCurrentInstance().update("wbTestPanel")in WorkbenchControllerBean.test()-method.

我认为代码也许是正确的，但是项目或运行时环境(Java 7 + JBoss 7.1.1)中的任何设置都阻止了primeface更新其他面板.您能给我一个提示，搜索什么吗?

I think that maybe the code is right, but there are any settings in the project or runtime environment (Java 7 + JBoss 7.1.1) that prevent primefaces from updating the other panel. Could you please give me a hint what to search for?

提前谢谢！

推荐答案

您确定调用了test()方法吗?如果是，您可以尝试使用以下更新表达式吗?

Are you sure that test() method is invoked?If yes, can you try with following update expression?

update="@([id$=wbTestPanel])"

否则，可能由于验证错误而未调用test()方法的情况.如果是这样，您可以使用debug或firebug对其进行检查.

Otherwise, it maybe the case that test() method is not called because of a validation error. If that is the case, you can inspect it with debug or firebug.
