I thought this error comes under User Interface , so posted and this is not from the exercise question

I got this error while implementing modal window in a portal using flow action(which coontain section having buttons with action activity and close).

Did you get any solution for this?

No

Hi All,

Usually this error will display if you are performing any action after current case is closed etc.

for example if in click of a button first action as close and next calling an activity etc on that case, since the case is closed activity would not be performed as it would be outside the current transaction

Please see the order of your actions performed on events
