Dependant LOV on Search Field

Question

Hi,
I am a newbie using ADF 11g. I am trying to create a Search page which takes 2 parameters.
1st Parameter is the Country LOV
2nd Parameter is the City LOV which is dependant on the 1st Parameter
I have done the below steps but no with no positive results.
1. The SearchVO is like this
select * from Dept
where
country = :pCountry and
city = :pCity
2. I create search in the following way
- Pull the ExecutewithParams as Search button on the screen
- Pull the table as table results
3. Process of creating the ParentLov.
- Pull the Parameter under the VO-> execute with Country params on to the screen as Select Choice Box
- Slect the CountryVO in the LOV as the View Object select required fields to be available on LOV and map with just Country Name Parameter
4. Process of creating the ChildLov.
- Pull the Parameter under the VO-> execute with City params on to the screen as Select Choice Box
- Slect the CityVO in the LOV as the View Object select required fields to be available on LOV and map with just CityNameParameter
5. Go to Page defintions,
- create a binding that maps the CityVO bind variable with the CountryName Parameter input value given in the step 3
- create a invoke action for that binding and place it before CityVO Iterator
6. I have set Partial trigger and autosubmit correctly for child and parent
Even after all this attemp I am not able to see the child getting populated. Child shows blank values
If I create a LOV for the View Object attributes that works but for Bind Variables, It simply doesnt..
Can somebdoy help me.. Most of the dependant LOV post talk abt VO attribute LOV but not abt a variable based LOV... URGENT respone/help required.
Thanks,
Shobz
