Sean, Thanks for your suggestion.
I have implemented ValueChangeListner to my BeanA and now I am getting the changes and basically storing the new value into the session. Doing this I am now able access changed value to BeanB. Now my further question is, can I explicitly fire the valueChangeEvent? If yes how? Because here what is happening is when my ListA is being populated I am getting the first item in the list selected, but I did not get the event fired so my session remains empty and hence I can not get that selected value in Bean B.
