Help need on how to load lov accoding to the locale value select

Question

Hi,
My scenario is , i'm having two button. One button for English locale(En) and another button for Dutch locale(Nl).
I'm having a database table which hold 2 columns, which are En and Nl.
I'm loading this columns value using an Lov
when i click the En button, Lov sholud load according to valus in En database column, and like that when i click Nl button it sholud load Lov according to values in Nl column.
I'm using a Session managed bean which used to set the locale.
i have implemented this scenario, but i got few bad problems.
1) my implemented method is not recommended as best practice
2) lov dosesn't change until i click a value on it.
In lov select query i used bind variable and put it value as adf.context.expressionEvaluator.evaluate('#{UserPreferences.language}')
this is not a best practice, so please help me to do this with in best practice.
Thanks.

Dear akash,
my scenario excatly same as this.
[http://biemond.blogspot.com/2009/02/change-language-locale-in-adf.html]
when user select dutch language i want to load the lov with dutch langage.
in this example lov values are hardcoded in the program, it didn't use any database columns.
in my scenario my lov is based on database table. that table contain two columns.
English | Dutch
One | een
Two | twee
Three | drie
in my view object i use a query like below.
Select English Mul
From User_Loacle
Where :plocale='en'
union all
Select Dutch Mul
From User_Loacle
Where :plocale='nl'
i assign a bind variable plocale.
i want to pass the above selected locale to this bind variable.
