Have you defined the message "error" in a properties file anywhere? Try the same test with a message from an existing message.properties file.

Thanks,
Mike

Hey MikeH,

The "error" is defined in webclient.properties. Other values from webclient.properties that I use in the webclient (in jsps that I override) are working fine.
I have tried using a resource key from an existing bundle in my webscript but it returns the same error.

Error during processing of the template 'Expression message('product_name') is undefined on line 43, column 49 in webclientextension/fileandlinkbrowser/externallink_selection.get.html.ftl.'. Please contact your system administrator.‍

Any idea?

Kind regards,

Geert

Hi Geert,

The error is occurring because the message() function is returning null, which Freemarker does not handle well. As Mike says, this is likely because the function cannot find that resource key.

Have you configured your message file into the application with Spring? You'll need to do this in order to use message bundles with Freemarker, as it uses a different mechanism to the web client JSPs. This also means that the strings defined in web-client.properties will not be available to Freemarker by default.

You can load in your own message bundle files by creating a new Spring config file (call it my-messages-context.xml or something similar) in your extension directory.

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>

<beans>

      <bean id="myResourceBundles" class="org.alfresco.i18n.ResourceBundleBootstrapComponent">
         <property name="resourceBundles">
              <list>
                   <value>alfresco.extension.my-messages</value>
              </list>
         </property>
      </bean>

</beans>

This example assumes your messages are defined in a file called my-messages.properties within your extension directory, if you change this you will need to update the resourceBundles list value appropriately in the config above.

You may be able to load in the contents of web-client.properties by adding it to the list above, but given it's size I would recommend using your own bundles instead if possible.

Cheers,
Will.

Hi Geert,
am trying to do something similar. create a web script which supports different languages. I did setup the properties file to pick up the message but how do i switch between the different languages. seems like simply switching the language of the browser does not work. do you have any details on how to do this.

Thanks
robain

heres how I managed to do it.
create the properties file in the extension directory and then load it.

<bean id="myResourceBundles" class="org.alfresco.i18n.ResourceBundleBootstrapComponent">
      <property name="mymessageBundles">
         <list>
            <value>alfresco.extension.mymessage</value>
         </list>
      </property>
   </bean>‍‍‍‍‍‍‍

now i pass the locale as a request paremeter and then set it using
I18NUtil.setLocale

I then use the following in the freemarker template files.
${message("messagename")}

hope this helps.

thanks
robain

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;
   }
}
