Undo row selection of af:table in selection listener method conditionally

Recently I have seen a question on OTN Jdeveloper forum and It was about table selection listener
Requirement is like this suppose user has to check a condition after selecting a row and if that condition is true only then new row will be selected else selected row should be previous one

It means undo row selection on validation(condition) failure
So In this post I am implementing same scenario and here I am using Departments table of HR Schema to prepare model and condition is that user should be able to select new row only if ManagerId is not null

How to queue SelectionEvent programmatically, Call af:table Selection Listener programmatically

Hello All
Hope you all are doing good :) 
Previously I have posted about defining custom selection listener for af:table and perform desired operation on selection event of table row

Selection Listener is fired when server receives a selection event from client means whenever user selects a row in table (Selection Event) then server process that event and execute selection listener defined in managed bean

And this post is about creating selection event programmatically without user interaction with table.
In ADF we can queue ActionEvent , ValueChangeEvent and in same manner we can create and queue SelectionEvent programmatically
