Hello Sergio,<br>Look at StRoot&gt;&gt;initializeListComponent (about three paragraphs below the code you posted in the tutorial). Of course, the sortBlock instance variable needs to been defined for StListComponent as <a href="http://well.as">well.as</a> its accessor methods. Then you need to call this method in StRoot&gt;&gt;initialize<br>
