我已经用 Group 和 Division 字段（带有值列表的组合框）构建了一个级联 LOV 。当我为 Group 选择一个值并单击Search and SelectDivision 字段的对话框时，SearchAndSelect 弹出窗口将 Group 和 Division 字段都作为搜索条件（在我的视图条件中定义）。
现在，有没有办法在弹出条件中填充Group 值，我知道 where 子句使用已经输入的 Group 值，但我想在 SearchAndSelect 弹出搜索区域中向用户显示它。
There is no declarative way of pre setting search field values in lov popup. Although it can be done by using a custom launchPopupListener for lov component. To know more about how to use lov popup listeners refer to Building Custom Lovs
Create a launchPopupListener method for your dependent lov.
<af:inputComboboxListOfValues id="inpClv2"
popupTitle="Search and Select: #{bindings.StateProvince.hints.label}"
value="#{bindings.StateProvince.inputValue}"
label="#{bindings.StateProvince.hints.label}"
model="#{bindings.StateProvince.listOfValuesModel}"
required="#{bindings.StateProvince.hints.mandatory}"
columns="#{bindings.StateProvince.hints.displayWidth}"
shortDesc="#{bindings.StateProvince.hints.tooltip}"
partialTriggers="inpClv1"
launchPopupListener="#{backingBeanScope.lovBean.stateLaunchPopupListener}">
</af:inputComboboxListOfValues>
In launchPopupListener set the value of search criteria attribute with the value from first lov.
public void stateLaunchPopupListener(LaunchPopupEvent launchPopupEvent)
{
UIXInputPopup lovComponent = (UIXInputPopup)launchPopupEvent.getSource();
ListOfValuesModel model = lovComponent.getModel();
if (model != null)
{
QueryDescriptor queryDesc = model.getQueryDescriptor();
/** Code to pre populate a Search and Select field**/
ConjunctionCriterion conCrit = queryDesc.getConjunctionCriterion();
List<Criterion> criterionList = conCrit.getCriterionList();
for (Criterion criterion: criterionList)
{
AttributeDescriptor attrDesc = ((AttributeCriterion) criterion).getAttribute();
if (attrDesc.getName().equalsIgnoreCase("CountryId"))
{
List values = ((AttributeCriterion) criterion).getValues();
values.set(0, "US"); //use the value from first lov
}
}
}
}
