Hi,
first of all if you need to escape your results use Freemarker's built-ins for Strings (and many other objects) as stated here http://freemarker.sourceforge.net/docs/index.html
Your ftl should look like

{
"Results" : [
  <#list countries as country>
    {"label":"${country.label?js_string}", "value":"${country.value?js_string}"},
   </#list>
   ]
}‍‍‍‍‍‍‍

where js_string converts your results in Javascript compliant strings.
Then the it's up to you to build up a correct json structure.
Remember that here you are creating the View part of a MVC pattern.
You can find more info about JSON here http://www.json.org/

Hi,
you get this error when the json is not well built. In this case, your problem is the comma.

Your code should be like that:

<#escape x as jsonUtils.encodeJSONString(x)>
{
"Results" : [
<#list countries as country>
    {"label":"${country.label}", "value":"${country.value}"}<#if countries_has_next>,</#if>
   </#list>
   ]
}
</#escape>

Regards
