ADF Dependent select one choice list

Question

hi all
i have two lists in my page, and the second one takes value from the first, but it is not working, the second list is empty always whatever i select in the first one.
i have searched many threads and it is not working. i also did the steps in the page http://www.oracle.com/technology/obe/obe11jdev/11/adfbc_new_features/adfbc.html#t2
this what i have did in details:
first list : LevelComboVO
select distinct group_level from mrcps_group_link
second list: GroupComboVO
select large_group_seq, group_level, symbol
from mrcps_group_link
where group_level = :selectedLevel
then i made a bind variable for the second list GroupComboVO named selectedLevel
for the first list LevelComboVO i made the following:
press plus on the ListOfValues:GroupLevel and for the list data source i have made new one for GroupComboVO and choosen the list attribute groupLevel and for ui hent i chosed groupLevel
then i have tested the AM but no data returned for GroupComboVO

Answer 1

first i have done the 2 view objects and the corresponding two select one choice list
for the first list i have made a managed bean for valueChangedListener -- > #{GrouplLevelBean.passLevel}
and i have put code as you told me :
package mrcps.view;
import javax.faces.context.FacesContext;
import javax.faces.event.ValueChangeEvent;
import oracle.adf.model.binding.DCBindingContainer;
import oracle.adf.model.binding.DCIteratorBinding;
import oracle.jbo.ViewObject;
public class GrouplLevelBean {
public GrouplLevelBean() {
public void passLevel(ValueChangeEvent valueChangeEvent) {
// Add event code here...
DCIteratorBinding testListIter1 = getItrtBindings("GroupComboVOObj1Iterator");
ViewObject vo1 = testListIter1.getViewObject();
vo1.setNamedWhereClauseParam("selectedLevel", valueChangeEvent);
vo1.executeQuery();
getItrtBindings( is giving me a red underline indication that method not found
