【问题描述】：

我为我的 DiplomeBean 创建了一个复杂的数据表，它显示正确交易是当我从列表中选择一行时，没有发生任何事情

我希望当我选择一行时，它会向我显示文凭的元素。

【解决方案1】：

也许尝试稍微修改一下，使其更像Primefaces showcase example。例如，尝试这样的操作：

...

<h:form id="form">

    ...

    <p:dataTable value="#{diplome.getAllDiplome()}"  var="d" paginator="true" rows="10"
        rowKey="diplome.idDiplome" selection="#{diplome.selectedDiplome}" selectionMode="single">  
        <p:ajax event="rowSelect" update=":form:display" oncomplete="PF('diplomeDialog').show()" />

        ...

    </p:dataTable>

    ...

    <p:dialog  header="Diplome Detail" widgetVar="diplomeDialog" resizable="false"  
          width="200" showEffect="explode" hideEffect="explode">  
        <h:panelGrid id="display">

           ...

        </h:panelGrid>
    </p:dialog>

</h:form>

...

我现在无法对此进行测试，但它似乎应该可以工作，因为它与展示的示例基本相同。
