Ben,
I am using a checkbox.
What I am planning to do is allow the user to check/select items/checkboxes on the book display page and check/select the books he wants to delete from Book store.
On submitting the form, I want to capture the set/list of checked choices so that I can take it as a array and pass it to my deleteBooks() method in my Action class.
Please let me know if I was not clear and I could append my sample code snippets.
I appreciate your swift replies
Thanks, ~Samy

not too sure what you mean by your question, but I'd say no, you don't need to pass in the array. You're using a String[] as the form property, right? Are you using multibox?
