Problem with "plain" mail and attachments

[aogier.netangel+seamframework.gmail.com]

There is a bug with SEAM 2.1.1.GA which prevents to send mail with attachments when the body type of a message is set to plain.

<m:attachment value="#{myAttachmentFile}"/>
<m:body type="plain">...</m:body>

will not send the file myAttachmentFile.

The workaround is to set it to html.

<m:attachment value="#{myAttachmentFile}"/>
<m:body type="html">...</m:body>

I've opened an issue in JIRA : JBSEAM-3970
