I did have a mail with a whole spiel as to how to go about it, but then thought that it wouldn't take long and be more of help if there was a "scratch-n-sniff" example you could go through also, so the solution is attached (requires everything needed to run Struts and the nested extension in the /WEB-INF/lib dir. Nightly build has it all, or older Struts with the nested extension's jar ( http://www.keyboardmonkey.com/struts )).
How it goes about it...
...in the list, the rows are marked up from separate objects in a list
and each has a submit button.
When one is clicked, because of the underlying nested property, the
individual objects' setter for the submit button will be called when the
form goes back to the struts servlet. From this setter it tells the root
bean that it's now to go to edit mode and set a standard property
("editingObject") in the root bean to return the object to be edited.
Then the action goes to the edit page which edits any object under the
"editingObject" property. Submit this form and it will update bean, the
action will set everything back, and there you have it.
When you consider this is the sum total of the entire process it's
really quite simple. And no hidden input fields or javascripts.
If you're not running the nightly build, get the nested extension from
here...

Another example using "edit view" style functionality...

For all the info you want about the nested extension, go to the "/struts
" link above.
