    Hello!

    I just discovered a problem on my server - When I relog my scoreboard goes away, and does not come back. If I try to turn my scoreboard on, it gives me an error, Player name can not be null (I clear the objectives..) Here is the scoreBoard class..


    PHP:
    package me.sgavster.qmc.func;

    import me.sgavster.qmc.util.MSG;

    import org.bukkit.Bukkit;
    import org.bukkit.OfflinePlayer;
    import org.bukkit.entity.Player;
    import org.bukkit.event.EventHandler;
    import org.bukkit.event.Listener;
    import org.bukkit.event.player.PlayerJoinEvent;
    import org.bukkit.scoreboard.DisplaySlot;
    import org.bukkit.scoreboard.Objective;
    import org.bukkit.scoreboard.Score;
    import org.bukkit.scoreboard.Scoreboard;
    import org.bukkit.scoreboard.ScoreboardManager;

    public class     scoreBoard implements Listener {

        public static     ScoreboardManager man = Bukkit.getScoreboardManager();
        public static     Scoreboard sameBoard;

        public static     void setNewBoard(Player p) {

            if (    sameBoard == null) {
                    Scoreboard b = man.getNewScoreboard();
                    Objective o = b.registerNewObjective("QuadularMC", "dummy");
                    o.setDisplaySlot(DisplaySlot.SIDEBAR);

                    Score votes = o
                            .getScore(loginHandler.getThings(p).getInt("votes") == 0 ? "§2None. /vote"
                                    : "§2" + loginHandler.getThings(p).getInt("votes"));
                    votes.setScore(1);

                    Score votez = o.getScore("§bVotes:");
                    votez.setScore(2);

                    Score deaths = o.getScore(loginHandler.getThings(p)
                        .    getInt("deaths") == 0 ? "§2None!" : "§2"
                            + loginHandler.getThings(p).getInt("deaths"));
                    deaths.setScore(3);

                    Score deathz = o.getScore("§bDeaths:");
                    deathz.setScore(4);

                    p.setScoreboard(b);

                    sameBoard = p.getScoreboard();

                    updateBoard(p);
            }
        }

        @    SuppressWarnings("deprecation")
        public static     void updateBoard(Player p) {
                sameBoard = p.getScoreboard();

            if (    sameBoard != null) {

                if (    loginHandler.getThings(p).getString("settings.scoreboard")
                        .    equalsIgnoreCase("yes")) {

                    if (    sameBoard.getPlayers() != null) {
                        for (    OfflinePlayer players : sameBoard.getPlayers()) {
                                sameBoard.resetScores(players.getName());
                        }
                    }

                        setNewBoard(p);
                        Objective oldO = sameBoard.getObjective("QuadularMC");
                        oldO.setDisplayName(MSG.quadularmc);
                        Score votes = oldO.getScore(loginHandler.getThings(p).getInt(
                                "votes") == 0 ? "§2None. /vote" : "§2"
                                + loginHandler.getThings(p).getInt("votes"));
                        votes.setScore(1);

                        Score votez = oldO.getScore("§bVotes:");
                        votez.setScore(2);

                        Score deaths = oldO.getScore(loginHandler.getThings(p).getInt(
                                "deaths") == 0 ? "§2None!" : "§2"
                                + loginHandler.getThings(p).getInt("deaths"));
                        deaths.setScore(3);

                        Score deathz = oldO.getScore("§bDeaths:");
                        deathz.setScore(4);

                        p.setScoreboard(sameBoard);
                        oldO.setDisplaySlot(DisplaySlot.SIDEBAR);
                } else {
                        setNewBoard(p);
                        p.getScoreboard().clearSlot(DisplaySlot.SIDEBAR);
                }
            }
        }

        @    EventHandler
            public void onJoin(PlayerJoinEvent e) {
                Player p = e.getPlayer();
                setNewBoard(p);
        }
    }
    I have no idea why this happens.. Thanks for any help!

    **Note, when I reload, or restart the server and I log on, it shows..

    EDIT: Anytime I call the updateBoard method when I have relogged I get an error. I really need this fixed.. Thanks.
    This is the code I would use for updating the scoreboard:

    PHP:
    scoreBoard.updateBoard(p);

    Please follow java naming conventions,
    Don't abuse static
    Can we see the stacktrace?
    From what I understand player variable turns to null for some reason. A little debug will help you

    @mine-care I was using static to acess it from another class...

    Here is the stacktrace:
