Filter ViewObject using bindings in ADF

Question

Hi All,
Jdeveloper Version : Oracle Jdeveloper 11.1.1.5.0
We are Creating 2 View Objects 1) DeptVO and 2) EmpVO . Dept VO : Select Depno,Dname From Dept, and we created Deptno as LOV  and Emp  VO : Select Empno From EMP Where Deptno = :P_Deptno
When we Drag and Drop Dept VO(Deptno) From Data Control to JSP Page we Created as ADF Select One Choice.
and for Emp VO(Empno) from DC to JSP Page as ADF Select One Choice.
Our requirement is Emp VO  contains list of Empno associated to Deptno we selected.
for example : Deptno 10 :   7782,7839 AND 7934.
                    Deptno 20 :   7369,7566,7788 etc..
this is we achieved through Backing Bean. but is there any other option we filter EmpVO through Bindings without writing Backing Bean.
Thanks,
kmr.

Hi
Excuse me,My English isn't very good.
you can set bind variable through EL, you should add Depno from Dept VO to the page binding and then set it to the bind variable
but After you choose Deptno you should run the second View Obj(Emp VO) through bean.
