QuestInfo Bug
 

Did anyone encounter this too?

GetJournalQuestInfo(questId) returns a empty array if on a german client and has crafting quest Alchemy writ with completed steps?

Yes. Wandamey figured out how it's correct:
Because the questIndex does not change, if you complete another quest with a lower index.

Uh, so when I'm iterating for i = 1, GetNumJournalQuests() I'm doing it wrong? Because that function returns the number of active quests, but they can be index 5, 7 and 13? :confused:

Quest index is not a quest ID. It is just an order representation number for the stock quest tool. So, you have to check the number if its valid before doing anything else.

Yes. That was a trap in Potion Maker. It was reported, that the writ potion was not found. After Wandamey told me, that the index does not change and I should use MAX_JOURNAL_QUESTS, I found that IsValidQuestIndex function in ESO code.

Apparently the only purpose of GetNumJournalQuests is to display that "Quests : num/25"

but the indexes change as soon as you complete a new step of any quest i think (i didn't exactly figured that one), which made this hard to detect. (not to mention that getting no nil error when iterating an empty array is a bit counterintuitive)

I found an even easier way to iterate recently but never used it and i didn't keep the test, maybe something along getnextquest. But anyway, it's just a 25 lines array.

What a mess, thanks all for the informations!

That was the main reason why I had to fix MiniMap quest pin updates so many times :)

What about QUEST_TRACKER.tracked, can't you just loop through it to get the quest indices? Every quest appears to be added to it. Although there is a function to remove a quest from the tracker
it doesn't look like its used. There are a few checks to call it & remove a quest from the tracker if QUEST_TRACKER:IsFull(), but since:
I don't see how that would ever happen, unless some addon manually removed a quest from the tracker.
