We're working on a web application using Tiles and Custom Tags (JSP). Has anyone had any luck explicitely setting tab order with these technologies?
One of the requirements is to offer all the same functionality from the keyboard, (so tab order becomes important). I can't think of any way to ensure that there will not be tab order conflicts if the same tabIndex value is set in two different elements in two different custom tags or tiles (short of preprocessing the page to generate unique tab indicies on the fly).
Right now, I'm recommending to not set the tab order at all and let the page layout dictate the tab order.
