Sorry to reanimate this thread, but if closePopup(‘id’) closes the popup with the specified ID, and closePopup(’’) closes the most recently opened popup, what does closePopup() do?
I’m wondering because in v8.1.13, I tried within a click event the action Popup Action->Close with an empty ID and it doesn’t do anything, same as system.perspective.closePopup(), and I’m wondering if they are somehow related.
