BlockingOutput Activity

Activity Description

This activity facilitates synchronous execution of workflow activities other than human activities with an active form.

This is typically used in forms, whose fields need to be updated based on the output of multiple workflow activities of the same workflow, executed one after the other, without closing the form.
