Repeating Return = Nowhere to return to

Question

The following sequence diagram fails with a message "Nowhere to return to" when duplicated in alt / else blocks, using latest version 1.2024.4:

@startuml autonumber skinparam strict uml box "app"     actor A     actor B end box A -> B  : first call alt #HoneyDew Success     return OK else #MistyRose Failure     return NO OK end @enduml

Commenting any of the return statements will render output, but without the corresponding return.

Expected: to return from B to A in both cases, but with different messages.

Answer 1

Does this work?

@startuml

autonumber

skinparam strict uml

box "app"

    actor A
    actor B

end box

A -> B  : first call

alt #HoneyDew Success
    B -> A : return OK
else #MistyRose Failure
    B -> A : return NO OK
end

Hi,
