My problem statement is when I invoke the "lookup" I can see it is showing all contacts regardless whether the contact is associated to the account or not.
I would like to display only those contacts belonging to that particular account.
Can someone point me some resources or provide me some highlevel guidelines as to how to achieve that ?
