EXT:formhandler – E-Mail – Separator for values from checkbox groups

Problem
When mailing form data from a checkbox group,
the resulting string is “value1,value2, …”

Cause
The default separator for array data is “,”.
There is no blank after the comma.

Solution
Change the separator string with config option “arrayValueSeparator”

finishers {
   1.class = Finisher_Mail
   1.config {
            ...
            user {
                  ...
 html.arrayValueSeparator = TEXT
 html.arrayValueSeparator.value = , 
 html.arrayValueSeparator.noTrimWrap = || |

             }
   }
}
