Incomplete Activity diagram from use cases

[seamoh]

Hello ,I transformed a usecase to Structured Scenario by using structured specification under Scenario tab of the usecase in enterprise architect(basic and alternate) .then I made an activity diagram generate diagram ---> activity . Enterprise Architect generated incomplete Activity diagram just showing the basic path without showing any alternate path. I am looking forward your answer ,thank you very much for your attention.

Hello all : I finally found the solution .I had just linked the alternative path to the basic path ,I hadn't assigned the steps to the alternate path ,therefore enterprise architect hadn't  showed the alternate path on the diagram .then I started to assign the steps for any alternative path and it worked completely .Thank you very much for all the people that read my question.
