Question

这是我的代码 -

def sendAcceptInvitationMail(invitation: Invitation) {
  val signupLink = Props.get("base.url").openOr("http://localhost:8080") + "/accounts/signup?code="+invitation.code.is
  S.eval(<lift:embed what="/templates-hidden/emails/accept_invitation">
            <lift:bind-at name="name">{invitation.name.is}</lift:bind-at>
            <lift:bind-at name="link"><a href={signupLink}>{signupLink}</a></lift:bind-at>
        </lift:embed>) match {
    case Full(msg) =>
      MailHelper.sendMail((invitation.email.is, invitation.name.is), S.?("subject.invitation.sent"), msg, MimeType.MIME_HTML)
      debug("Accept invitation mail sent for: "+invitation.email.is)

    case _ => warn("Invitation Accept Email not sent to: "+invitation.email.is+". Problem preparing message")
  }
}

我得到了这个例外。

我进行了调试，发现使用S.?('subject.invitation.sent')从资源中读取属性时会抛出此异常。但我在许多其他代码片段中使用相同的函数调用，没有任何异常。需要帮助。

S包中的大多数项都要求有效的会话可用，并且通常要求访问发生在与Http请求相同的线程中。 MailHelper你写的是什么？我知道电梯的Mailer.sendMail是通过一个演员异步发生的，所以这可能与它有关。

如果您还没有尝试，可以尝试检索翻译。类似的东西：

case Full(msg) =>
      val i18nConfirmation = S.?("subject.invitation.sent")
      MailHelper.sendMail((invitation.email.is, invitation.name.is), i18nConfirmation, msg, MimeType.MIME_HTML)
      debug("Accept invitation mail sent for: "+invitation.email.is)
