Hi Ken, You need to be able to get the initial value of the first list in your Action Class, and then you can do the same thing the first time that you do on updates, in exactly the same way. We do this on edits, where we get the value out of the database. Always remember that Struts is two-way. If you want something to have an initial value other than the default, then in your Action class set the field in the form that gets set when the user puts a value in, in the jsp.

I do have a related question. I have a jsp page that shows a history of activities I have the same two select fields on this jsp. Each row on the page is its own form so that they can be updated seperately. Is there a way to fill the second select list based on the value of the first list when the page is populated. I have gotten it to change when the 1st select is changed, but ai want it to display correctly when the page is first displayed.
