Thanks Musachy. I changed the success action forward to point to the original page (or really the action which creates that page) and that works, though it does rebuild the page, which is unfortunate overhead. But it does do what I need to do, so I'm happy.
Thank you.

Because you don't want to change the current page, you could do this by making an asynchronous request. I'm probably wrong, but I don't think you can make a post, and stay on the same page (unless you are returning the same page from the action of course). regards musachy Christopher Loschen wrote: > Hi all, > > > > I'm honestly unsure if I'm having a problem with Struts (sadly, 1.1) or > with Javascript, or something else.
