I coded this up for your example:

MyApp.properties
================

label.attendees=All attendees include:  ${attendees}

Usage
=====

        List<String> attendees = new ArrayList<String>();
        attendees.add( "Johan" );
        attendees.add( "James" );
        add( new AttendeeLabel( "attendees", "label.attendees", this,
attendees ) );

Code
====

public class AttendeeLabel extends Label
{
    public AttendeeLabel( String id, String resourceKey, Component
component, List<String> attendees )
    {
        super( id, new StringResourceModel( resourceKey, component,
new Model( new Attendees( attendees ) ) ) );
    }

    private static class Attendees implements Serializable
    {
        private List<String> attendees;


        public Attendees( List<String> attendees )
        {
            this.attendees = attendees;
        }


        public String getAttendees()
        {
            StringBuffer sb = new StringBuffer();

            for ( Iterator<String> iterator = attendees.iterator();
iterator.hasNext(); )
            {
                String attendee = iterator.next();

                sb.append( attendee );

                if ( iterator.hasNext() )
                {
                    sb.append( " " );
                }
            }

            return sb.toString();
        }
    }
}


HTH,

Enrique
