Hi, The video describes how the when condition operates with regards to "Refresh" condition. The observation you made is the correct behavior. The property associated with the current section is considered to satisfy the when condition. If you have an activity before the "Refresh-Other section" and set a property according to your requirement on the current section's class and using that property in the when condition of "Refresh-Other section" should do it.
Immediately after activity run, i have configured reload section with when expression. after running the activity, it is not validating when rule. it is directly refreshing the other section and focus is gone.
