Looks like UIDropDownMenu_StopCounting and UIDropDownMenu_StartCounting were removed in 8.3

I don't really mess with dropdowns, maybe @sylvanaar or @Pazza can look at that one.

[Pazza]

I haven't been keeping up over the years with the changes they have been making. Could you test and see what happens if you comment out that line? From looking at the diff quickly I can't see a replacement of that call, just its removal. Let me know if it things still behave.

[dartraiden]

I removed these 2 lines (because the second gives an error too)

    f.scroll:SetScript("OnEnter", function(self) _G.UIDropDownMenu_StopCounting(self:GetParent()) end);
    f.scroll:SetScript("OnLeave", function(self) _G.UIDropDownMenu_StartCounting(self:GetParent()) end);

Errors are gone, drop-down menu still works perfectly...

[Pazza]

Thanks for confirming that. Can I assume this was only removed in Retail?

[MysticalOS]

That's possibly been broken for a long time, so it'd affect classic too since it's based off retail 8.1.5. it needs testing, so don't assume

EDIT, oh op saays it's an 8.3 change so maybe not broken in classic YET. but eventually classic is supposed to migrate to 9.0 so it's probably better to rework

[Pazza]

Thanks @MysticalOS ... I think better to check for existence of _G.UIDropDownMenu_StopCounting, if so, then it'll keep executing that code. It was too long ago to remember why I had to put it in there.

[dartraiden]

Hmmm, I don't know why... but this menu looks like this on my main character (retail) - many items + scrollbars

and like this on all other characters (Retail + Classic) - only few items, so no scrollbar

Errors appear only when using menu scrollbar
