Question

我有一个rich：dataTable，并且当用户点击详细信息按钮时，喜欢向rich：popupPanel中的每一行显示详细信息。

我这样做

                <h:panelGrid columns="3" columnClasses="titleCell">
                    <h:form id="form">
                        <rich:dataScroller for="table" maxPages="5" />
                        <rich:dataTable value="#{tournSelectionBean.tournaments}"
                            var="tourn" id="table" rows="10">
                            <rich:column>
                                <f:facet name="header">
                                    <h:outputText value="Name" />
                                </f:facet>
                                <h:outputText value="#{tourn.name}" />
                            </rich:column>
                            <rich:column>
                            <a4j:commandButton value="Detail"
                                action="#{tournSelectionBean.setCurrentTournament(tourn)}"
                                render=":detailpopup"
                                oncomplete="#{rich:component('detailpopup')}.show();" />
                        </rich:column>
                        </rich:dataTable>
                        <rich:dataScroller for="table" maxPages="5" />
                    </h:form>
                </h:panelGrid>

                <rich:popupPanel id="detailpopup" modal="true" resizeable="false"
                    autosized="true">
                    <f:facet name="header">
                        <h:outputText value="#{tournSelectionBean.currentTournament.name}" />
                    </f:facet>
                    <f:facet name="controls">
                        <h:outputLink value="#"
                            onclick="#{rich:component('detailpopup')}.hide(); return false;">

                        </h:outputLink>
                    </f:facet>
                    <h:panelGrid columns="2" columnClasses="titleCell">

                        <h:outputLabel value="City" />
                        <h:outputLabel
                            value="#{tournSelectionBean.currentTournament.city}" />

                    </h:panelGrid>
                    <a href="#" onclick="#{rich:component('detailpopup')}.hide()">Close</a>
                </rich:popupPanel>

setPropertyActionListener正确设置ID，弹出窗口按预期打开。但弹出窗口显示创建视图时bean中的锦标赛的详细信息（而不是由propertyactionlistner设置的锦标赛）。

我怎样才能做到这一点？

编辑：更新了上面的代码并添加了Bean：

@Named("tournSelectionBean")
@ViewScoped
public class TournamentSelectionBean implements Serializable {

  @EJB
  private TournamentControllerInterface tournamentController;

  private List<Tournament> tournaments;

  private Tournament currentTournament;

  @PostConstruct
  public void init() {
    tournaments = tournamentController.loadTournaments(true, false);
  }

  /**
   * @return the tournaments
   */
  public List<Tournament> getTournaments() {
    return tournaments;
  }

  /**
   * @param tournaments
   *          the tournaments to set
   */
  public void setTournaments(List<Tournament> tournaments) {
    this.tournaments = tournaments;
  }

  /**
   * @return the currentTournament
   */
  public Tournament getCurrentTournament() {
    return currentTournament;
  }

  /**
   * @param currentTournament the currentTournament to set
   */
  public void setCurrentTournament(Tournament currentTournament) {
    this.currentTournament = currentTournament;
  }

}

你需要告诉JSF在打开它之前重新渲染弹出式HTML：

<a4j:commandButton value="Detail" 
    action="#{tournSelectionBean.setCurrentTournament(tourn)}"
    render=":detailpopup"
    oncomplete="#{rich:component('detailpopup')}.show();" />

注意：如果popupPanel中有<h:form>，则重新渲染完整弹出窗口时可能会出现问题。将所有内容放在表单内的<h:panelGroup>中，然后重新呈现该表单。

在rich：popupPanel中显示bean值
