Sequence diagragram: Message destroys object

[Elvys]

Hallo there,

I have again a problem which I can't solve by myself.

I wanted in my project to show how a session-object creates new object required for the session.
This fore a sequence diagram is created and the object were inserted.
Then I created a message from the session-object to the other object and set the "Lifecycle" as new (in the Message properties).
So war everything went like expected

But now I wanted to show the after the object are created the session calls a specific method (with a message) to set them in a certain state.

The problem, when I create the message from session to another one, it appears the symbol indicate the lifetime of the object is over.

But I don't want this symbol appears. In the diagram the objects has just to be initialized.

Could you help me, please?

The help in http://www.sparxsystems.com/resources/uml2_tutorial/uml2_sequencediagram.html [Chapter Lifeline Start and End] was not sufficient.

Maybe it would also help to know how to determine when an object has to be destroyed.
Thank you in advance

Your EA is probably configured to use the "garbage collection" model in sequence diagrams for objects that are explicitly created in a sequence. You can change this behavior to explicit destruction in Tools->Options... Diagram/Sequence by unticking the Garbage Collect checkbox.

Thank you! It works fine!
