ADF_186：使用ReturnPopupListener接收Input Text with LOV的返回值

运行环境：JDeveloper 11.1.2.2.0 + Oracle Database 10g Express Edition 10.2.0.1。

使用Input Text with LOV组件时，返回值会自动绑定并显示在InputText中。
如果需要通过程序获取返回值，可以定制returnPopupListener。

重要步骤说明：

1. inputListOfValues组件代码如下：

<af:inputListOfValues id="jobIdId" popupTitle="Search and Select: #{bindings.JobId.hints.label}"
                      value="#{bindings.JobId.inputValue}" label="#{bindings.JobId.hints.label}"
                      model="#{bindings.JobId.listOfValuesModel}"
                      required="#{bindings.JobId.hints.mandatory}"
                      columns="#{bindings.JobId.hints.displayWidth}"
                      shortDesc="#{bindings.JobId.hints.tooltip}" autoSubmit="true"
                      returnPopupListener="#{myBackingBean.jobIdReturnPopupListener}">
    <f:validator binding="#{bindings.JobId.validator}"/>
    <af:autoSuggestBehavior suggestedItems="#{bindings.JobId.suggestedItems}"/>
</af:inputListOfValues>

2. Managed Bean的代码

    public void jobIdReturnPopupListener(ReturnPopupEvent returnPopupEvent) {
        RowKeySet rowKeySet = (RowKeySet)returnPopupEvent.getReturnValue();
        Iterator rksIterator = rowKeySet.iterator();
        while (rksIterator.hasNext()) {
            List key = (List)rksIterator.next();
            RichInputListOfValues lovComp = (RichInputListOfValues)returnPopupEvent.getSource();
            ListOfValuesModel lovModel = lovComp.getModel();
            CollectionModel collectionModel = lovModel.getTableModel().getCollectionModel();
            collectionModel.setRowKey(key);
            JUCtrlHierBinding treeBinding = (JUCtrlHierBinding)collectionModel.getWrappedData();

            JUCtrlHierNodeBinding nodeBinding = treeBinding.findNodeByKeyPath(key);
            String[] strs = nodeBinding.getAttributeNames();
            for (String str : strs) {
                System.out.println("########################### " + str + ":" + nodeBinding.getAttribute(str));
            }
        }
    }

说明：这里可以获取到LOV的所有字段的值。

3. 运行
输出如下：
########################### JobId:eee
########################### JobTitle:EEE
########################### MaxSalary:2
########################### MinSalary:1
