Object representation inconsistent

[cpns]

In EA, on an object diagram, the <object name>:<classifier> label is underlined, whereas on the communication diagram they are not. Is this correct, and if so, what is the purpose of the distinction?

I note that the user manual shows objects on communication diagrams with the underline!

I also found that thomaskilian raised a similar issue, albeit several years ago, but the conclusion seemed to be that the underline should be there.

Should it not also be there for objects on sequence diagrams (in fact objects anywhere)?

Am I just missing some preference selection possibly?

Yes. Have a look in the UML 2.1 specifications under "InstanceSpecification" and "Lifeline" for full descriptions of the notation, along with examples of both.

The page that describes communication diagrams is one of many that have been updated for EA 7.0.
