Oracle I Expense
1) The Back and Next button are common to all pages. So to refer these buttons i am planning to use the below logic
Get the event using pageContext.getParameter("event");
Compare this event with GOTO_EVENT
Get the source using pageContext.getParameter(SOURCE_PARAM)
Compare it with OIENavBar
I guess this will help us to handle the Back and Next buttons on any OIE page.
To put the validation on a particular page, i am using NavigationUtility.getCurrentPage(pageContext) and comparing it with the OIE page which i need to validate
