i come up with easy solution. thanks for help:
.properties
attendees.names=All attendees include: {0}
webpage
// example list, but do not know size of list at all times
List<String> attendees = new ArrayList<String>();
attendees.add("Attendee 1");
attendees.add("Attendee 2");
attendees.add("Attendee 3");
add(new Label("attendee-names", new StringResourceModel("attendees.names",
this, null, new Object[]{ Arrays.toString(attendees.toArray()) })));
output:
All attendees include: [Attendee 1, Attendee 2, Attendee 3]
