REST - Failure to fill multiple lined CF

I’m trying to fill a multiple value CF from a REST command using curl, but no value is added to the field.

Queue: General
Custom Field: Events (id=8) type: “Enter multiple values”

curl command to create a new ticket:

curl -s
-H “Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8”
-H “Accept_Language: en-US,en;q=0.5”
-H “Accept_Encoding: gzip, deflate”
–data-urlencode content=“id: ticket/new
Queue: General
Requestor: dummy.requestor@localhost
Priority: 0
Subject: REST Ticket
CF.{8}: This is a one lined event string
Text: Ticket description
” ‘http://hostname/REST/1.0/ticket/new?user=root&pass=password

If I change it’s type to “Enter one value” the value is added with the exact same command.

I even tried setting it manually from the web interface and making a REST request on the ticket, copying the CF.{8} line and pasting it on the curl command, to no effect.

Is this a bug on the REST interface?
