I create an Activity, which runs a Workflow which send an email. But I cannot
see how to set a link to the Activity in the email. The properties available
in the Email designer do not include a link to the Activity.
Corrent me if I am wrong, but it seems I must add an attribute (URL) to
each of the Activity Entities ( Email, PhoneCall, etc ), then a PostCreate
plugin which generates the url of the new Activity and assigns this URL to
the Activity. Then when the Activity Workflow fires it will have the link to
itself to put in the Email.
