How work function C_AuctionHouse.PostIte
 

Hey.
This code work in chat:

/run C_AuctionHouse.PostItem(ItemLocation:CreateFromBagAndSlot(0, 1), 1, 1, nil, 190080000)

but dont work in my addon:

local function OnEvent(self, event, ...)
if event == "ITEM_SEARCH_RESULTS_UPDATED"
C_AuctionHouse.PostItem(ItemLocation:CreateFromBagAndSlot(0, 1), 1, 1, nil, 190080000)
end
end

local f = CreateFrame("Frame")
f:RegisterEvent("ITEM_SEARCH_RESULTS_UPDATED")
f:SetScript("OnEvent", OnEvent)

it requires a hardware event, did you test putting it on a button?

You can show example? Thanks
