I am working on a struts-based web application and I have an interesting design issue that I'd like to get some feedback on. I think this problem is actually quite generic and there must be some good ideas out there already that I could sponge off!
Basically I have a struts form with a bunch of fields that will be presented to the user through the usual JSP-based view. The user will have the opportunity to makes edits and then submit to an action. What I would like to do is be able to identify which fields changed and then take certain actions based on these changes. Here is one rough ideas I have so far. Any thoughts on this plus additional ideas would be greatly appreciated. 1.) Extend ActionForm and customize the populate method so that it makes a copy of the old version of the form that is already stored in the session (since it will have session scope) 2.) Populate new form 3.) Compare two forms and store list of changes in new form 4.) Discard copy of old. Any thoughts, comments?
