Separate getStatusMessage function

[eileenmcnaughton]

Overview

Separate getStatusMessage function

Before

Parent & child class use the same getStatusMessage function but follow different paths within it

After

Child class implements the function itself, functionality separated

Technical Details

The CRM_Event_Form_Task_Register form was once part of CRM_Event_Form_Participant

It now extends it & the goal is to disentangle it from the parent.

In general _single is only set for the parent & describes actions for that whereas the Register form is a task that can act on many
