After upgrading, I started receiving an error stating:
The PAYLOAD argument passed to the send function is not of type
coldbox.system.beans.Mail
It was simple enough to resolve. All that needed to happen was to
change the EnvironmentSafeMailService.cfc so that all references of
type *coldbox.system.beans.Mail* where changed to *any*.
This brings up the question, why would you ever type anything in CF? I
have been working with typeless or type optional languages, like CF
and Groovy, for many years and I do not really see any compelling
reason.
My two cents worth...
