This can’t be an official problem since it’s an undocumented api method (this might even be intended functionality), but here it is anyway.

Whichever formula was last registered on the page will be returned by

skuid.formula.getFunction

,no matter what you put as the parameter (even nothing).

reproduction page below. Just press the register buttons and you’ll see that whichever register button you press last is called (open the console to see) when you press either call button.
