Why not use a list view for the comment list?
If you want to show a message with "No comments", then:
add(new Label("nocomments", "No comments") { boolean isVisible() {
return comments == null || comments.isEmpty();} });
<p wicket:id="comments">this is the listview</p>
<p wicket:id="nocomments">this is the no comments label</p>
