Squence Diagrams with embedded Components

[Major Peanut]

Is it possible to create Sequence diagrams that shows embedded Components grouped together (similar to the Inline Sequence Element link below)? As I could not see how to do in EA 10 (10.0.1005).

E.g. I have a component [CompA], which has with in it two 'sub' components [CompA1 & CompA2] and a separate component [CompB].
- CompA1 has a required interface [IntX] and a provided interface [IntY]
- CompA2 has a required interface [IntY] and provided interface [IntZ]

- CompB has required interface [IntZ]

So I want to show flow from CompA through to CompB including the sub-components on a sequence diagram, but also show CompA as the parent of CompA1/A2, i.e. grouped lifeline for CompA1/A2 under CompA, including their interfaces.

BTW is this possible if CompA has IntX and IntZ as interfaces which are delegated to the internal components? (Not sure if/how delegated interfaces work/show on sequences diagrams.)

The page you have linked to is a description of how to do exactly that.

The part that it doesn't mention is that it has used a class that is already modeled with child parts and ports.

This feature seems quite useful, but it is not standard UML, is it?

Yes, it is. See Figure 14.21 in UML 2.4.1 (or 17.21 from UML 2.5)

Wow, I missed that one. Time to update my sequence diagrams :-)
Thanks!
