I am building XLL + RTD in the same dll. The RTD is not called directly from Excel but through wrapper formula. Similar to sample here Custom Functions in Excel: Part V, XLL-RTDs
The functionality seems to be working but when I edit formula inputs manually Excel confuses the edited formula with the one with topic number 0. Both ConnectData for edited item and DisconnectData for old item are called with correct topic ids.
What might be solution for this?
