Hello Sergio,
Look at StRoot>>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 well.as its accessor methods.
Then you need to call this method in StRoot>>initialize
Warm regards
