Title: Communication Diagram Question
Post by: davisford on October 04, 2004, 01:39:40 pm

Hi, in the Help section on Communication Diagrams, there is an example diagram shown as a user login collaboration.  I am noting that associations are numbered and the direction is specified by an arrow with the message.  

I could not figure out how to specify the direction of the message in the Communication Diagram on the Association properties page.  I can specifiy bi-directional, source->dest., dest.->source, and unspecified, but this is for the association endpoints.  How can I duplicate the diagram shown in the help?

Thanks in advance.

Davis

Actually it is not the associations that are numbered, but the messages.

To add a message from an object to another, right-click on an association and select "Add message from ... to ....". This is how you specify the direction.

If you need to reorder the messages later, go to the Diagram menu and click on "Sequence communication messages".

If you continue reading the "Related topics" ("Messages for Communication Diagrams") from the help page that you have found, you will learn these things, and more.
