工作中:这是我的工作 rich:listShuttle 当源值和目标值是字符串列表时。
<强>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>
<强>2。支持 bean
//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;
}
<强>3。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,以便 sourceValue 和 targetValue 是复杂对象 (DMPJurisdiction) 的列表,而不是像以前那样的字符串列表。我为此编写了一个转换器。
<强>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>
<强>2。支持 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;
}
<强>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;
}
}
<强>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}":属性“jurisdictionList”不可写在类型 java.util.List 上),detail=(javax.el.PropertyNotFoundException:/html/workcase/type/dmp/admin/AddCompany.xhtml @55,98 sourceValue="#{companyAdminAction.jurisdictionList}": 属性“jurisdictionList”在类型 java.util.List 上不可写)] ||||
注意:只是附注,我成功地为 selectOneMenu 使用了相同的 dmpJurisdictionConverter,如下所示,在不同的不相关 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>
最佳答案
您可以使用接缝标签“<”s:convertEntity/>
它会自动进行转换,但复杂对象必须是实体
