[news.eclipse.tools.uml2] Re: Order of Messages on Interaction

["James Bruck" <jbruck@xxxxxxxxxx>]

Hi Leila,

I'm not familiar with Magic draw but from a UML perspective, the order of
lifelines, messages or events within interactions cannot be guaranteed.
That is to say that they can occur in any order and still be part of a valid
model.
The only way you can draw conclusions about ordering of messages is by
finding out the OccurrenceSpecifications that the message refer to.
OccurrenceSpecifications would be placed in the fragments collection of the
interaction and that collection is ordered.   The OccurrenceSpecifications
refer to events.

Cheers,

- James.
