Can we have a cycle in an activity diagram?
For example in Registeration Use case, a form must be filled out and give to the secretary. It may not be filled correctly, so the secretary would call him later to come and fill out the form again. Can we show it in activity via a cycle? or we have to have to end state in Registeration Activity Diagram, one when the form is filled correctly and one when it is not?
Thanks for any help.
