Apparently 8.1 broke a function in VFL that ended breaking all editbox in RDX (typically for Vars Scripted nodes)
The fix I found consisted in changing the function VFL/UI/Indent.lua:getCaretPos(editbox) (line ~880), replace all the code in this function by :
Code:
local function getCaretPos(editbox)
return editbox:GetCursorPosition()
end
I still have a somewhat workable version of RDX if it still interest anyone. I'm not sure I really want to spend the time to "officially" maintain it though.
