Struts e-mail validator doesn't handle null?

[Ryan White]

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 ([e-mail]) but somehow it interprets nothing as being a correct e-mail too...

Thanks

<field property="email" depends="required , email">
<arg0 key="form.email"/>
</field>

use this in your validation.xml file

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.

What version of Struts are you using? Maybe you could use the validwhen rule? Or when the user pressed the Add button, you could populate a hidden field and perform validation against that field.
