While working on email templates the other day - for the grouped reminder template.  

Is it still an issue for preview ? ...ie it appeared that when I previewed what would typically be a grouped reminder.  And certainly the attached document was a grouped reminder.   The object being passed to the Email template was the customer object.  not The document as per the special template fields.

I couldnt use `openvpms:get(.,'customer.entity.firstName')` but `openvpms:get(.,'firstName')` works fine

I had assumed the `.` would be the fields associated with the special grouped reminders.  https://openvpms.org/documentation/csh/2.1/reference/reportFields#special

which would indicate customer is a field.
