Ajax to work in Grails Framework(repost)

The following to be written using GRAILS FRAMEWORK We need a grails GSP page displays list of person information. Name Age Description The page needs to get the data (list of person) from the controller every two seconds. The page also needs to submit the description & age input by the user (ideally all the form values of the page) and get the same reflected back and displayed on the same page. The user should be able to scroll vertically and horizontally without being affected by the ajax update. The preferred way to do this is using AJAX/Prototype.
