Jboss Seam Mail Attachment Problem

jboss-seam-mail 2.2.0.GA library has a bug which causes mails to be rendered without attachments. An issue has been opened in Jboss's issue tracker and a patch has been released about it. (JBSEAM-4442) In spite of applying patch to the library the bug is still alive. If you are experiencing the same problem, you should switch to an older and stable version like 2.0.2 to overcome this bug.
