This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
An action on Input.jsp returns Output.jsp as outcome to the Actor. How do we display this basic interaction in sequence diagram? By default the return arrow comes back to where we started from (which is Input.jsp) but that is not what actually happens.
Is it fair to remove the return arrow from Controller to Input.jsp
Actor --> Input.jsp --> Controller --> Backend
Will - If "return" arrow (as you depicted) is synchronous invocation to Output.jsp from OtherStuff, then will Actor invoke same "execution occurance" on Output.jsp (verical rectangle running down) for the next activity? I hope that does not break any UML standard.
