I have a requirement to navigate back to a standard OAF page from a custom OAF page

I have launched a custom OAF page using " pageContext.setForwardURL" from a COTS/standard page. Now after completing the transactions from a custom page, want to navigate back to COTS/standard page. I have added a "GO BACK" button and trying to use pageContext.setForwardURL method to navigate back to the page but it does not work.

Is there any standard way of doing this in the framework ?
