Hello,
Why is the address variable not reset to null in the doAfterBody() function
? (as is done in the doStartTag() in AddReceipientTag )
The problem I had was when I was doing:
<mt:addrecipient type="to"><c:out
value="${param.friendsEmail1}"/></mt:addrecipient>
<mt:addrecipient type="to"><c:out
value="${param.friendsEmail2}"/></mt:addrecipient>
friendsEmail1 is always set, friendsEmail2 can be the empty string.
When <c:out value="${param.friendsEmail2}"/> outputs an empty string then
the mailer taglib sends a mail with 2 times the friendsEmail1 address in the
TO field of the email.
Adding an address = null fixes this problem.
FYI: the current code I'm talking about:
public final int doStartTag() throws JspException {
// parent tag must be a MailTag, gives access to methods in parent
myparent =
(MailTag)javax.servlet.jsp.tagext.TagSupport.findAncestorWithClass(this,
MailTag.class);
if (myparent == null)
throw new JspException("addrecipient tag not nested within mail
tag");
// Make sure type is set..either "to", "cc", or "bcc"
if ((type != null) && (type.equalsIgnoreCase("to") ||
type.equalsIgnoreCase("cc") ||
type.equalsIgnoreCase("bcc"))) {
if (address != null) {
// Try to see if the address attribute was used.
if (type.equalsIgnoreCase("to"))
// set to in the parent tag
myparent.addTo(address);
if (type.equalsIgnoreCase("cc"))
// set cc in the parent tag
myparent.addCc(address);
if (type.equalsIgnoreCase("bcc"))
// set bcc in the parent tag
myparent.addBcc(address);
address = null; // reset address
return SKIP_BODY;
} else
return EVAL_BODY_TAG;
} else
throw new JspException("The type attribute is not set. " +
" Specify either \"to\", \"cc\", or
\"bcc\".");
}
