Solve the following python programming problem given the following code:
def registerExtenderCallbacks(self, callbacks) : 
    self._callbacks = callbacks 
    self._helpers = callbacks.getHelpers () 
    callbacks.setExtensionName ('AuthMatrix - v0.5.2') 
    self._db = MatrixDB () 
    self._fc = JFileChooser () 
    selfExtender = self 
    self._selectedColumn = (- 1) 
    self._selectedRow = (- 1) 
    self._userTable = UserTable (self, model = UserTableModel (self._db)) 
    roleScrollPane = JScrollPane (self._userTable) 
    self._userTable.redrawTable () 
    self._messageTable = MessageTable (self, model = MessageTableModel (self._db)) 
    messageScrollPane = JScrollPane (self._messageTable) 
    self._messageTable.redrawTable () 
    def addPopup(component, popup) : 
        class genericMouseListener (MouseAdapter) : 
            def mousePressed(self, e) : 
                if e.isPopupTrigger () : 
                    self.showMenu (e) 
def mouseReleased(self, e) : 
                if e.isPopupTrigger () : 
                    self.showMenu (e) 
def showMenu(self, e) : 
                if (type (component) is JTableHeader) : 
                    table = component.getTable () 
                    column = component.columnAtPoint (e.getPoint ()) 
                    if (((type (table) is MessageTable) and (column >= selfExtender._db.STATIC_MESSAGE_TABLE_COLUMN_COUNT)) or ((type (table) is UserTable) and (column >= selfExtender._db.STATIC_USER_TABLE_COLUMN_COUNT))) : 
                        selfExtender._selectedColumn = column 
else : 
                        return 
else : 
                    selfExtender._selectedRow = component.rowAtPoint (e.getPoint ()) 
popup.show (e.getComponent (), e.getX (), e.getY ()) 
component.addMouseListener (genericMouseListener ()) 
class actionRunMessage (ActionListener) : 
        def actionPerformed(self, e) : 
            if (selfExtender._selectedRow >= 0) : 
                if (selfExtender._selectedRow not in selfExtender._messageTable.getSelectedRows ()) : 
                    indexes = [selfExtender._db.getMessageByRow...

    
    

    Fix the buggy line: callbacks.customizeUiComponent (roleScrollPane._userTable)
