工作：这是我的工作丰富：当 sourceValue 和目标值是字符串列表时的 listShuttle。

1.JSF页面

<rich:listShuttle id="companyJurisdictionShutle"
            sourceValue="#{companyAdminAction.statesList}"
            targetValue="#{companyAdminAction.selectedStates}"
            var="item" orderControlsVisible="false" fastOrderControlsVisible="false"
            sourceCaptionLabel="Available"
            targetCaptionLabel="Selected" styleClass="lishShuttle">
                 <rich:column>
                     #{item}
                 </rich:column>
</rich:listShuttle>

2. 支持豆

//sourceValue                    
public List<String> getStatesList() {

    for (DMPJurisdiction dmpJurisdiction: jurisdictionList) {
        if(!statesList.contains(dmpJurisdiction.getJurisName())) {
            statesList.add(dmpJurisdiction.getJurisName());
        }
    }
    return statesList;
}

//targetValue
public List<String> getSelectedStates() {
    return selectedStates;
}

3. 价值对象

public class DMPJurisdiction implements Serializable {

    /** serial version UID **/
    private final static Long serialVersionUID = 109892748283726L;

    /** jurisdiction id **/
    private Long jurisId;

    /** name **/
    private String jurisName;

    /** description **/
    private String jurisDescription;

    /** code **/
    private String jurisCode;

    //Getters and Setters

}

不工作：我更改了列表穿梭，因此 sourceValue 和 targetValue 是复杂对象列表（DMPJurisdiction），而不是之前的字符串列表。为此我写了一个转换器。

1.JSF页面

<rich:listShuttle id="companyJurisdictionShutle"
      sourceValue="#{companyAdminAction.jurisdictionList}"
      targetValue="#{companyAdminAction.targetJurisdictionList}"
      converter="#{dmpJurisdictionConverter}"
      var="item" orderControlsVisible="false" fastOrderControlsVisible="false"
      sourceCaptionLabel="Available"
      targetCaptionLabel="Selected" styleClass="lishShuttle">
             <rich:column>
                #{item.jurisName}
             </rich:column>
 </rich:listShuttle>

2. Backing Bean：现在返回上面列出的复杂对象DMPJurisdiction的列表。

//sourceValue
public List<DMPJurisdiction> getJurisdictionList() {
    return jurisdictionList;
}

//targetValue
    public List<DMPJurisdiction> getTargetJurisdictionList() {
    return targetJurisdictionList;
}

3.转换器

public class DmpJurisdictionConverter implements javax.faces.convert.Converter {

      public Object getAsObject(FacesContext facesContext, UIComponent uiComponent, String s) {
          List<DMPJurisdiction> dmpJurisdictionList = Cache.loadAllDmpJurisdictions();
            for (DMPJurisdiction dmpJurisdiction : dmpJurisdictionList) {
                if (dmpJurisdiction.getJurisName().equals(s)) {
                    return dmpJurisdiction;
                }
            }
            return null;
      }

      public String getAsString(FacesContext facesContext, UIComponent uiComponent, Object o) {
          List<DMPJurisdiction> dmpJurisdictionList = Cache.loadAllDmpJurisdictions();
            for (DMPJurisdiction dmpJurisdiction : dmpJurisdictionList) {
                if (((DMPJurisdiction) o).getJurisName().equals(dmpJurisdiction.getJurisName())) {
                    return dmpJurisdiction.getJurisName();
                }
            }
            return null;
      }

}

4.错误： sourceId=accountWorkcaseOpenTabForm:addDmpCompanySubview:companyJurisdictionShutle[severity=(ERROR 2), summary=(javax.el.PropertyNotFoundException: /html/workcase/type/dmp/admin/AddCompany.xhtml @55,98 sourceValue="#{companyAdminAction.jurisdictionList}": Property 'jurisdictionList' not writable on type java.util.List), detail=(javax.el.PropertyNotFoundException: /html/workcase/type/dmp/admin/AddCompany.xhtml @55,98 sourceValue="#{companyAdminAction.jurisdictionList}": Property 'jurisdictionList' not writable on type java.util.List)] ||||

注意：顺便说一句，我正在为 selectOneMenu 成功使用相同的 dmpJurisdictionConverter，如下所示，在另一个不相关的JSF 页面中。

<h:selectOneMenu value="#{companyAdminAction.dmpJurisdiction}" converter="#{dmpJurisdictionConverter}">
                    <s:selectItems var="item" value="#{companyAdminAction.jurisdictionList}" label="#{item.jurisName}"
                                   hideNoSelectionLabel="true" noSelectionLabel="-- Select Jurisdiction --"/>
                    <a4j:support event="onchange" action="#{companyAdminAction.loadCompanyList()}"
                             reRender="dmpCompanies"/>
            </h:selectOneMenu>

你可以使用接缝标签“<”s:convertEntity/>

它会自动进行转换，但复杂对象必须是实体

我正在使用它的getter getStatesList加载 sourceValue="#{companyAdminAction.statesList}" 。它应该单独加载，因为在页面呈现时会多次调用 getter 和 setter。我不得不将加载 statesList 移动到在 bean 初始化期间调用的另一个私有方法。
