Avoiding destroy of lifelines in Sequence diagrams

[Alinen]

Hi,

when an object is created in a sequence diagram, its lifeline automatically is destroyed after the last access. An example can be seen here:


All four created objects get their lifeline destroyed. Especially object 2 and 4 have lifeline that is very short.
Hower the diagram shows only a part of the full lifecycle of these objects and they should never be destroyed in this diagram. Is there a way to achieve this?

Usually you get this if the last message has a Lifecycle Destroy.

This is not the case. All messages (except the creating ones) have no lifecycle specified.

I have been looking for this option (obviously not very hard) for years.  Allow me to update the path within the new UI:
Start | Preferences | Diagram | Sequence | Activation Indicator | GarbageCollect (auto delete).

Hehe. In the next EA version it will be in a completely different location (reminds me of Monty Python).
