invoice sending script

invoice.groovy

def run(args) {
  def invoice = args.entity

  if (invoice.confirmationStatus == ConfirmationStatus.NOT_SENT) {
    def m = Email.create("Tax Invoice")
    m.bind(invoice: invoice)
    m.to(invoice.contact)

    m.send()

    invoice.setConfirmationStatus(ConfirmationStatus.SENT)
    args.context.commitChanges()
  }
}

Hmm... Did you mean :

def m = Email.create("Tax Invoice")
m.bind(invoice)

If so, this is quite easy to implement if we want to.
