It seems mail node is blocking, I just tried. I would like to handle when the sending of a mail fails. I saw that this node can handle exceptions, so I added one : <mail-node name="notifier_valideur" to="#{demande.valideur.email}" template="task-assign"> | <subject>#{mailSubject}</subject> | <text>#{mailText}</text> | <exception-handler exception-class="javax.mail.SendFailedException"> | <action class="InvalidEmailAddressExceptionHandler" name="mailFailed"></action> | </exception-handler> | <exception-handler exception-class="com.sun.mail.smtp.SMTPAddressFailedException"> | <action class="InvalidEmailAddressExceptionHandler" name="smtpFailed"></action> | </exception-handler> | <transition to="valider_demande"></transition> | </mail-node> Result is that I still get the exception, and workflow stops here. I even don't get inside the InvalidEmailAddressExceptionHandler class. What's wrong? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4227438#...
