I've got exactly the same problem as this using Seam 2.0.0.CR2 on JBoss 4.2.0.GA. I've tried the async send in the mail example and it shows the same issue. Has anyone found a solution to this? I've stripped my own app back so that it has no variables in the mail template. Everything is hard-coded so I doubt it's a conversation scope issue as suggested above. All of the other types of send in the example app work aside from the async. Here's the stack trace from the example: | 17:11:35,054 INFO [MailSession] Creating JavaMail Session (localhost:2500) | 17:11:35,060 INFO [MailSession] connected to mail server | 17:11:54,872 ERROR
