[rt-users] adding custom field type, how to force single value

In order make sure that we're solving the correct problem, since my
previous post was terse, and I'm not sure whether I used all the right key
words, please allow me to elaborate:

Based on a similar treatment by a colleague, I have created
local/html/Elements/CustomField_Local.pm

 15 #$FieldTypes{JSON_Encoded_Resource_Field} = {
 16 #  sort_order => 36,
 17 #  selection_type => 0,
 18 #
 19 #  labels => [
 20 #    'Fill in one Encoded Resource Text Area',
 21 #  ],
 22 #};

The I
created local/html/Elements/EditCustomFieldJSON_Encoded_Resource_Field and
 local/html/Elements/ShowCustomFieldJSON_Encoded_Resource_Field

Which do what I need them to - pretty print the JSON so a human can read it
and edit it if necessary.

But RT thinks this custom field type allows multiple entries per field, and
so pukes all over the pretty-printed JSON.

When I use a straight "Fill in one text area" RT is ok with the JSON, but
the JSON is not pretty printed.


Thank you again.

Len.
