We have a requirement that the user be prompted if any changes have been
made on a form, and they try to navigate away. I've divided this up
into sub tasks:
- Iterating through properties of a bean.
- Render properties as hidden fields.
- Render some JavaScript to check for modifications.
The last one's going to be the tough one, but it's manageable. Before I
start writing some custom tags, I was wondering if Struts or its
dependent libs had any of this functionality already. I'd likely need
some type of property class, and a way of discerning, in JSP tags
(preferable), if a property is nested, a collection, a boolean or a
string. I think those four types should cover it. I've no problem
writing the facility myself but I'd hate to duplicate work that's
already there.
Thanks,
Scott
