Achievement Page trouble

[vroominator]

Yes, I'm having trouble with Achievement pages. Done a quick search, and found that I'm not the only one who's had this issue, but the fixes in other threads haven't worked for me.

I know it has trouble if there's only 1 achievement, but I have 6, and some of them are sub-achieves of others in the same list. Achievements with parent achievements in this list also won't show what achievement they require, but instead show their description, without me having the parent achievement.

Here's the code I'm using, if it's any help

 

	soShiny = new Achievement(8000, "soShiny", 0, 0, ingotSilver, AchievementList.acquireIron).registerAchievement();
	addAchievementName("soShiny", "It's so shiny!");
	addAchievementDesc("soShiny", "Smelt a Silver Ingot");

	wizardHarry = new Achievement(8001, "wizardHarry", 0, 1, wand, Sorcery.anotherTable).setSpecial().registerAchievement();
	addAchievementName("wizardHarry", "You're a Wizard, Harry");
	addAchievementDesc("wizardHarry", "Craft a Wand at a Wandcrafting Table");

	loveStory = new Achievement(8002, "loveStory", 0, 2, spellbook, Sorcery.inventor).registerAchievement();
	addAchievementName("loveStory", "Still a better love story than Twilight");
	addAchievementDesc("loveStory", "Craft a Spellbook");

	babbyFormed = new Achievement(8003, "babbyFormed", 0, 3, (new ItemStack(arcanehalf, 1, 0)), AchievementList.buildWorkBench).registerAchievement();
	addAchievementName("babbyFormed", "How is Babby Formed?");
	addAchievementDesc("babbyFormed", "Craft an Incubator");

	anotherTable = new Achievement(8004, "anotherTable", 0, 4, (new ItemStack(machine, 1, 1)), Sorcery.inventor).registerAchievement();
	addAchievementName("anotherTable", "ANOTHER Crafting Table?");
	addAchievementDesc("anotherTable", "Craft a Wandcrafting Table");

	inventor = new Achievement(8005, "inventor", 0, 5, (new ItemStack(machine, 1, 0)), AchievementList.buildWorkBench).registerAchievement();
	addAchievementName("inventor", "Inventor");
	addAchievementDesc("inventor", "Craft a Tinkering Table");

	achPage = new AchievementPage("Sorcery", babbyFormed, soShiny, wizardHarry, loveStory, anotherTable, inventor);
	AchievementPage.registerAchievementPage(achPage);

 

Sorry if this is in the wrong section, I'm not sure whether this belongs under the Bug Reports or Modder Support section.

Stumbled upon the same bug, gave up searching as well, so I studied the code

 

It renders the white screen when the achievement page only containes achievements without parent achievements.

 

That prevents Gui.drawRect() (called from drawHorizontalLine() or drawVerticalLine()) from being called, which apparently is required due to some GL Options being set. If I were to make a guess, it would be GL11.glBlendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);

 

Dear MCForge devs: Please look into this. Should be only a matter of minutes to fix from here on. Thanks!

I figured out what I did wrong, and as usual, dumb mistake. I was registering certain achievements before their parent achieves, and the game doesn't like it when you do that.
