Controlling View Criteria Hints At Runtime

I came across a requirement where in I need to control view criteria hint(Display/Hide) based on logged in user or some user parameter.

I will now discuss & show a reusable way of controlling at a single point.

Model:

In EmployeeVO, I have defined a view criteria for employee search as below.

Department Id is a list of values defined on DepartmentVO.

I will show case here how to control display of DepartmentId LOV based on logged in user role.

I created EmployeeVOImpl & overridden below method: 

If you notice, getCriteriaItemAttributeHints calls a Util method to determine whether to display/hide view criteria item based on logged in users role. If user is in role "super-user" then the Department Id LOV is displayed otherwise hidden.

For testing purpose, I enabled security in application & defined two test user & roles as below.

Now when I login as user barber, I don't see the Department Id LOV:

If I login as scott, I do see Department Id LOV:

Hope this helps!!!
