Hi Gonzalo, You suggest that both message and event can be one to many relation vis-a-vis the sender and receiver. Could you give example of this one to many relation for a "message"? I always was under the impression that message is a one-to-one relation

I think Jean has already explained how you can get different behavior in your example, depending on time (in general, depending on the state of the receiver), with the same operation signature, so I won't insist on it. But I would like to comment another aspect. In his answer to you, Jean seems to think that the relationship sender-receiver is one-to-one in operation calls, and one-to-many in signal sends. I don't agree that this is the case in UML. The sending of a message is the result of an action in the sender object. In the UML metamodel, each Action specifies the target of the action by means of an object set expression which resolves into zero or more instances [UML Standard, version 1.4, page 2-120], so that, in principle, both for a signal and for the invocation of an operation the receiver may be a set of objects [Reference Manual, page 334] (however, the documentation sometimes suggests that the receiver of an operation call must be a single object, while the receivers of a signal may be multiple [Reference Manual, page 333]). ************************************************************************ * Rose Forum is a public venue for ideas and discussions. * For technical support, visit http://www.rational.com/support * * Admin.Subscription Requests: [EMAIL PROTECTED] * Archive of messages: http://www.rational.com/support/usergroups/rose/rose_forum.jsp * Other Requests: [EMAIL PROTECTED] * * To unsubscribe from the list, please send email * * To: [EMAIL PROTECTED] * Subject:<BLANK> * Body: unsubscribe rose_forum * *************************************************************************
