I have created a standalone region and used the same in my workflow. Now when notification goes to Manager for Approval/Rejection, he can click on the link and see the details for that notification. Now, my requirement is to navigate back to notification with Back browser button once he checks the details. I am not getting that how can I acheive this. Kindly let me know how can Manager go back to that notification and take necessary action.
As per my understanding you have some link in Notification Page, which opens in same window. You can make the link open in new window by setting link item property target frame to to_blank should open the page in New Window.
If this doesn't help then you can refer Notifications (Workflow Worklist) section in developer guide.
