[xwiki-devs] Mail sender API doesn't work with template?

Hello, On Xwiki 6.4, it seem that new mail sender API doesn't work. I didn't manage to use exemple 3 and 4 from doc: http://extensions.xwiki.org/xwiki/bin/view/Extension/Mail+Sender+API#HExampl... I use Admin account and use this code: http://www.xwiki.org/xwiki/bin/view/ReleaseNotes/ReleaseNotesXWiki641#HIssue... I attached a Xwiki/Mail objetct to MailTemplatePage but no mail are sent and /bin/admin/XWiki/XWikiPreferences?editor=globaladmin§ion=emailStatus page are empty. Example 1 and 2 are working (I fixed a typo). Pascal B.
