我尝试显示带有服务器信息的数据表，并在弹出窗口中显示服务器的详细信息，但是当单击该按钮时，服务器的详细信息不会出现在弹出窗口中，我不知道如何设置服务器在bean中的选择和在弹出窗口中显示它。

Answer 1

在bean中存储服务器标识符（名称或ID）（请参阅my answer）并在弹出窗口中重复使用。

示例：

    <h:form id="notesForm">
        <rich:messages />

        <a4j:jsFunction name="selectRow" oncomplete="#{rich:component('noteDetails')}.show()"
            render="noteDetailsForm">
            <a4j:param name="noteId" assignTo="#{chNotesAction.currentNoteId}"
                converter="javax.faces.Long" />
        </a4j:jsFunction>

        <rich:dataTable id="noteTable" style="width: 100%"
            value="#{chNotesAction.notesList}" var="rs"
            rowClasses="oddrow, evenrow" columnClasses="nowrap,"
            rows="#{referenceData.recordsPerPage}" sortMode="single"
            onrowclick="selectRow('#{rs.noteLogId}')"
            rowKeyVar="currRow">

            <rich:column id="date">
                <f:facet name="header">
                    <h:outputText value="#{msg.entryDate}" />
                </f:facet>
                <h:outputText value="#{rs.changeDate}" />
            </rich:column>

            <rich:column>
                <f:facet name="header">
                    <h:outputText value="#{msg.notesType}" />
                </f:facet>
                <h:outputText value="#{rs.noteType}" />
            </rich:column>

            <f:facet name="footer">
                <rich:dataScroller renderIfSinglePage="false" for="noteTable"
                    stepControls="show" fastControls="hide" />
            </f:facet>
        </rich:dataTable>
    </h:form>

    <rich:popupPanel id="noteDetails" autosized="true">
        <f:facet name="header">
            <h:panelGroup>
                <center>
                    <h:outputText value="#{msg.noteTitle}" />
                </center>
            </h:panelGroup>
        </f:facet>
        <f:facet name="controls">
            <h:graphicImage value="/images/close.png" 
                style="cursor:pointer" onclick="#{rich:component('noteDetails')}.hide()" />
        </f:facet>
        <h:form id="noteDetailsForm">
            <rich:messages />

            <h:panelGrid columns="2" columnClasses="nowrap,">
                <h:outputText value="#{msg.notes}" />
                <h:inputTextarea value="#{chNoteForm.noteText}" label="#{msg.notes}"
                    rows="10" cols="50" style="resize:none;">
                    <f:validateLength maximum="4000" />
                </h:inputTextarea>

                <h:outputText value="#{msg.clientInitiated}" />
                <h:selectBooleanCheckbox value="#{chNoteForm.clientInitiated}" />
            </h:panelGrid>
        </h:form>
    </rich:popupPanel>

Bean部分：

    private Long currentNoteId;
    public void setCurrentNoteId(Long noteId) {
        this.currentNoteId = noteId;
        // setup popup related data here
        }
    }

Richfaces：在弹出窗口中显示详细信息[commandbutton，action和popupPanel]
