Tasks with mail notification (notify="yes") fail if the assigned actor has no e-mail address. --------------------------------------------------------------------------------------------- Key: JBPM-850 URL: https://jira.jboss.org/jira/browse/JBPM-850 Project: JBoss jBPM Issue Type: Patch Affects Versions: jBPM 3.2.0 Reporter: Bruno Dumon Fix For: jBPM 3.3.0 Attachments: noaddress_mail_patch.txt In our system, it can occur users have not configured an email address, in which case they should not (and cannot) receive email notifications. So our AddressResolver implementation returns a null email address in that case. Currently this will make jBPM try to send a mail with no recipients, causing JavaMail to raise an exception. The attached patch (against current CVS) changes things such that a mail is not send when there are no recipients.
