Populating static values in addition to database value in select one choice

Question

Hi All,
We are using jdev 11.1.1.2.0.
I am populationg a select one choice based on a read only VO. The vo is populating fine,but in addition to the values from the database I want to add two static values. I want to add 'select customer' and 'all customer'.
Currently I am doing this using UNION in the sql query of my VO. WhenI add union in my sql query its taking more time to load the value from the database.
Is this the proper adf way to do it? Is there someother way to attain it.
Following is the query I am using to populate one of the VO's
SELECT * FROM(
SELECT ID,NAME,3 SORT_ORDER FROM CUSTOMER
UNION
SELECT -1,'SELECT CUSTOMER,1 FROM DUAL
UNION
SELECT -2,'ALL CUSTOMER,2 FROM DUAL)
ORDER BY SORT_ORDER,NAME
Please advice
Susan

Hi,
You can do this usecase by populating the values to SelectOneChoice Programmatically.
<af:selectOneChoice label="List"
binding="#{MyTestBean.myTestListComponent}">
<f:selectItems value="#{MyTestBean.listOfItems}"/>
</af:selectOneChoice>
backing bean code will be:
public List<SelectItem> getListOfItems() {
List<SelectItem> items= new ArrayList<SelectItem>();
SelectItem si = new SelectItem();
//if u trying to populate data from VO then u have set the values
DCBindingContainer dcBindings = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding iterBind = (DCIteratorBinding)dcBindings.get("DepartmentsView1Iterator");
for(int i=0;i<iterBind.getEstimatedRowCount();i++)
Row row = iterBind.getViewObject().getRowAtRangeIndex(i);
if(row!=null)
si = new SelectItem();
si.setLabel((String)row.getAttribute("DepartmentName"));
si.setValue(row.getAttribute("DepartmentId"));
items.add(si);
//here you can add the static values;
si = new SelectItem();
si.setLabel("Static Value1");
si.setValue("Static1");
items.add(si);
si = new SelectItem();
si.setLabel("Static Value2");
si.setValue("Static2");
items.add(si);
return items;
}
