General Board / Re: Activity diagrams - sub diagram capability?

« on: September 25, 2002, 11:59:08 am »

thanks Jason, still not sure though. I can drag the "sub" onto the "main" but I can only do this once, which defeats the object as I want to use it in several places in the "main". I think you are suggesting that I create an activity in the "main" and create an association link to the "sub"; am I right? This works but is not intuitive, and the reader would find it unwieldy to trace back to the "sub". Can you confirm if I'm interpreting you correctly? Thanks once again.

General Board / Activity diagrams - sub diagram capability?

« on: September 25, 2002, 06:50:52 am »

UML permits several activities, states, decsion blocks and objects to be connected up as a general work flow and to be bundled up as a sub-diagram, which can then be used as a single activity in other diagrams. Does EA permit this? I've looked in the help section but I can't see how; and I've tried experimenting but failed to find a way.

General Board / roles Vs instances in collaboration diagrams

« on: August 13, 2002, 04:13:25 am »

Collaboration diagrams can be specification or instance level. specification level uses class roles rather than instances. The syntax differs between a role and an instance: the role name is NOT underlined, whereas the instance name is. I've found with EA that a role can only be acheived if the role is NOT anonymous (in other words, you add text to the role field). But the UML spec suggests that un-named roles are permissible. The following would be a role: :BankAccount, whereas an instance would be: :BankAccount. Is it me that is missing something, or EA?

General Board / Re: How to link diagrams to use cases?

Hey Frank, this was one of my concerns. Mr Sparx points out that a diagram is not a UML element so there is no direct UML linking. However, from a CASE tool viewpoint you should be able to hyperlink from where you want to where you want. I would suggest that this becomes a requested feature.

General Board / alternative branch in collaboration diagram

« on: August 05, 2002, 11:58:21 am »

I'm a newbie but I'm led to understand that conditional paths can be drawn in collaboration diagrams. i.e. 2a[modemResponded]:setBaudRate with an alternative path 2b[timeout]:sendErrorMessage. Problem is that if you add a message to an association on the diagram the numbering order is added automatically, leaving you powerless to add 2a followed by 2b. Instead, you're left with 2 followed by 3. I can't see anyway of overriding the system to add your own numbering system.
