ScrollList not displaying data...

[Phinix]

This feels like one of those mysterious undocumented language failures that just doesn't work in ZOS's LUA implementation and fails without warning or error.

I have a ScrollList that I populate with data when I click some navigation buttons, and this works fine.

I try and populate the same list from another function and it fails without error, displaying nothing.

What is odd is if I print the data strings I am pushing to the datalist table they all show up correctly formatted just like the data lists I push from the buttons that work.

There is literally no reason this shouldn't work, and yet, it doesn't.

Is there some undocumented failure with ScrollLists?

Works:

function PLD.ScrollList(list)
	ZO_ScrollList_Clear(MainFrameListFrameList)
    local datalist = ZO_ScrollList_GetDataList(MainFrameListFrameList)
	local known
	local nametable
	local listsize = PLD.TableSize(nametable, list)
	for i = 1, listsize do
		local level = nametable[i].Level
		local saved = PLDGetTierSavedVar(i, list, 0)
		if IsItemLinkRecipeKnown(nametable[i].Link) == false then
			if saved == 1 then
				known = "|cffffff[s] |r"
			elseif saved == 0 then
				known = "|cc3c3c3[  ] |r"
			end
		else
			known = "|cffff00[*] |r"
		end
		datalist[i] = ZO_ScrollList_CreateDataEntry( 1, 
		{
			RecipeName = known .. "|c3a92ff" .. nametable[i].Name .. "|r" .. "|cffffff " .. level .. "|r",
		}
		)
	end
	ZO_ScrollList_Commit(MainFrameListFrameList, datalist)
end

Doesn't work:

function PLD.Test()
	ZO_ScrollList_Clear(MainFrameListFrameList)
    local datalist = ZO_ScrollList_GetDataList(MainFrameListFrameList)
	local known
	local searchtext = MainFrameSelectionFrameSearchBox:GetText():gsub('%W',''):lower()
	for i = 1, 486 do
		local name = ProvisioningLabels[i].Name:gsub('%W',''):lower()
		if (string.find(name,searchtext) ~= nil) then
			local ln = tonumber(ProvisioningLabels[i].Position)
			local level = ProvisioningLabels[ln].Level
			local saved = PLDGetTierSavedVar(i, 15, ln)			
			if IsItemLinkRecipeKnown(ProvisioningLinks[ln].Link) == false then
				if saved == 1 then
					known = "|cffffff[s] |r"
				elseif saved == 0 then
					known = "|cc3c3c3[  ] |r"
				end
			else
				known = "|cffff00[*] |r"
			end
			datalist[i] = ZO_ScrollList_CreateDataEntry( 1, 
			{
				RecipeName = known .. "|c3a92ff" .. ProvisioningLabels[ln].Name .. "|r" .. "|cffffff " .. level .. "|r",
			}
			)
		end
	end
	ZO_ScrollList_Commit(MainFrameListFrameList, datalist)
end

No errors, just fails to populate the list. Debug text shows all values are correct.
INFURIATING.

In the working code the index counter i of datalist is continous, while in the not working code, datalist could have gaps, because some values of i are not inserted to datalist.
Try to use a new index counter: datalist[rowNumber] instead using i. or table.insert

Wow, you're a life saver man!

I created a new local variable in the main function and iterated it + 1 for each match and used that as the datalist index and it is working like a charm.

If you are using integer index for the tables you could just use the function
table.insert(tableName, value).
