I18N in Freemarker template

[geert]

Hello,

I am trying to make my  webscripts available in different languages.
On the wiki I found some information on the message(String) method, but when I try to use it I always get the following error:

Error during processing of the template 'Expression message('error') is undefined on line 25, column 82 in /webclientextension/imagebrowser/image_upload.post.html.status.ftl.'. Please contact your system administrator.

freemarker.core.InvalidReferenceException - Expression message('error') is undefined on line 25, column 82 in /webclientextension/imagebrowser/image_upload.post.html.status.ftl.

I use the message tag as follows in my ftl file:

${message('error')}‍

When I leave the message methods everything works perfect so normally my webscript configuration is correct.
I am using Alfresco Community 2.9.0C.

If you need more information, feel free to ask.

Thanks in advance!

its a seperate project where i need the internationalization for webscripts.
heres the webscript backing java code, if thats what you were asking for.

package com.someco.web.scripts;

import java.util.HashMap;
import java.util.Map;
import java.util.Locale;

import org.alfresco.i18n.I18NUtil;
import org.alfresco.repo.security.authentication.AuthenticationUtil;
import org.alfresco.web.scripts.DeclarativeWebScript;
import org.alfresco.web.scripts.WebScriptRequest;
import org.alfresco.web.scripts.WebScriptStatus;

public class LanguageHandlerScript extends DeclarativeWebScript
{
   
   @Override
   protected Map<String, Object> executeImpl(WebScriptRequest req, WebScriptStatus status)
   {
      String language = req.getParameter("language");
      
      if(language!=null)
         I18NUtil.setLocale(new Locale(language));
            
      Map model = new HashMap<String, Object>();
      return model;
   }
}
