在我的 crud 应用程序中，我想选择一行，然后在弹出窗口中显示该行数据。导航到另一个页面有效并显示数据。当我尝试在弹出窗口中显示它时，不会显示任何值。我可能是错的，但我认为在方法 prepareView 完成之前会打开弹出窗口。

代码块：

<h:column>
                            <f:facet name="header">
                                <h:outputText value="&nbsp;"/>
                            </f:facet>
                            <h:commandLink id="myLink" value="Action" action="#{timeLoggingDetailController.prepareView}" rendered="#{item.timeLoggingId eq AdminTimeLogging.filteredId}" styleClass="auto-style5">
                                <rich:componentControl target="popup" operation="show"/>
                            </h:commandLink>
                        </h:column>
                    </h:dataTable>
                </h:panelGroup>
            </h:form>
            <rich:popupPanel id="popup" modal="false" autosized="true" resizeable="false" domElementAttachment="form">
                <f:facet name="header">
                    <h:outputText value="Approval level" />
                </f:facet>
                <f:facet name="controls">

                            return false;">
                        Close
                    </h:outputLink>

您可能想要使用<a4j:commandLink>，它提供oncomplete了在操作完成时触发的事件。

这应该适合你：

<a4j:commandLink id="myLink" value="Action" actionListener="#{timeLoggingDetailController.prepareView}" rendered="#{item.timeLoggingId eq AdminTimeLogging.filteredId}" styleClass="auto-style5">
    <rich:componentControl event="complete" target="popup" operation="show"/>
</a4j:commandLink>
