I have some AJAX in my app which works fine to add new people to a list
shown on-screen. The problem comes if I try to delete one of the new
people. Once saved, there is no problem, as there is an id to delete
with. The problem comes when I try to remove a new person from the
screen. The closest I got was a div around all people and a remove of
that div. All the delete links ( one each person) would delete the first
item on the list..(of course since it only had the div holding
everything to use). I tried div_for and content_tag, but each needed an
id to work with..
Please help.. Thanks
some code..
