Aaron,
I have a sample that does something similar to what I think you are asking.
I did not use a single submit. I used multiple submits and sent them to the
same Action class.
Here is the full JSP page from the application I developed for Wrox Pro JSP
2nd edition chapter 21 on Struts.
See comments added in the JSP page and the comments at the end of the page.

I provided the ability for the user to change the quantity of the shopping
cart item. I would assume that you would want the ability to change the
salary. You could accomplish this in much the same way by making the
employee name or id (assuming you have access to an id) and the salary both
hidden parameters for each individual form that represents a row.
Granted this may not be the most elegant solution, but I believe that it is
a simple solution. Sometimes simple is not elegant! :-)
Hope this helps...
If I can every get NewParticles to update my source code you will be able to
download the latest edition from the http://www.newparticles.com/struts web
site. The latest version is similar to new one, but I've started using the
commons packages and I've clean up the JSP pages to use less scriptlet
coding.
Enjoy,
Steve
