I have a form that has 2 e-mail fields. One is the entry field with an "add-email" button next to it that, when clicked, adds the e-mail to a CSV list in the other (locked) e-mail field. this is part of an overall form. Apparently, the built in Struts e-mail validator doesn't handle a null condition because it is allowing me to submit a null with the add-email button. I can't set it as required or the main form won't let me submit without an e-mail in that field which should be empty upon final form submission. The user should have clicked add-email to populate whats in the e-mail field to the CSV list of e-mails.
What can I do here? the Struts e-mail validator works in ensuring the correct format (email@example.com) but somehow it interprets nothing as being a correct e-mail too...
I can't do that because then it is required for the main form on the page. This is another form within the main form. The e-mail field has an add-email button that adds whatever is in that field to a text box with a list of multiple e-mail addresses. So when the user goes to submit the main form, they should have added the email in the email field to the multi e-mail text box therefore making the email field blank upon final submission.
