Initially i tried doing that using a call to a method on click of a link but then i realized that it will still output the entire HTML including the left navigation, header and footer. I created a custom component to capture the part of the Page. I provided 2 attributes - targetPath - where to save the Html output and isCaptured - to conditionally capture It works well. Thanks for all your help.

On click of this button I want to capture the generated HTML for the current view I am on, truncate the left navigation, header and the footer. Extract the body HTML and open a save dialog box to save this HTML page with only body as attachment. Any ideas of how it could be done using JSF?
