My Activation bar does not return in drawing. (sequence Diagram)

Question

Hi

I am trying to generate a sequence diagram, but got stuck since my activation bar does not return:

 

@startuml

title Test 1

C -> A
activate A
A -> A
activate A
A -> A
activate A
A -> A
activate A
A -> B
activate B
activate A
B --> A
deactivate B
A -> A
activate A

deactivate A
deactivate A
deactivate A
A --> C
deactivate A

Probably I am doing something wrong

Answer 1

I am not sure, but one "deactivate A" line may be missing in your example.

In you use:

@startuml
title Test 1

C -> A
activate A
A -> A
activate A
A -> A
activate A
A -> A
activate A
A -> B
activate B
activate A
B --> A
deactivate B
A -> A
activate A

deactivate A
deactivate A
deactivate A
deactivate A
deactivate A
A --> C
deactivate A
@enduml

You'll get:

Is this what you are expecting ?
