Sequence Diagrams

[EA_Nj]

I was trying to setup location  marks e.g. {location = Server} on the instances in my sequence diagram. But I didn't find any menu option that would help me do this.  Am I missing something?

Also how can I set the sequence numbers on the messages in my sequence diagram? I tried looking up the properties but that didn't help.


Thanks,
Jamal

Hello,

We have recently added this ability (build 465, due out in the next couple of days) to show location information for classes and objects, however sequence objects are not as easy, so we will be looking at including this into a future version.  

Currently EA does not support numbering sequence messages, however we will take note of your request and see if we can include it in a future version.

In build 465, can I specifiy location information in a Logical Diagram (e.g. class diagram) or deployment diagram? In either case I didn't see anything new on the GUI that specifically indicates location information.

I also checked the help file to see if it had any information about this new feature that you were referring to.

Can you point it out?

Hi,

The implementation is based on setting a tagged value:

tag='location'
value='<wherever>'

for the class or object. If you then use the 'Set Feature Visibility' context menu option for a Class or Object and check the 'Tagged Values' check box, the element will display an extra compartment detailing tags - including the location tag.

Hope this explains,

I created an object on my sequence diagram (made sure that the object type was "Object" or "Class"...tried both of them).

Then I added the tag value as you had suggested.  I set the visibilility feature as well. But the tag value still didn't display on the diagram. I have build 480 v. 3.1.0

Hi,

Referring back to my earlier post I indicated that Sequence diagrams were a special case and would be looked at in the future. The functionality described was for logical, deployment, component diagrams etc., and for a limited set of elements - mainly for classes.

In a logical diagram for example, you create a class, set responsibilites, tagged values and/or constraints, then in the Specify Feature Visibility dialog for that class, enable the required compartments ... you should get something like the example below:



This is what you can do now - we will look at sequence diagrams in the future.

Yeah, I would very much like to see sequence number optionally available on the message sequence diagram.  We have system engineers that use Visio to generate MSCs.  It takes them a while to "get it just right."  If you can add sequence numbers to the diagram then I can convince them that Enterprise Architect would provide them a "near replacement" to Visio; as far as their needs are.

Also, our seqence charts have many objects interacting with a large number of messages in the sequence.  Is it possible to indicate page breaks (either for portrait or landscape layout) on the sequence chart layout window and use the page breaks as a point where to break the SC into multiple pictures in the generated RTF file?

Hi Raymond,

What sort of numbering system is required?

IN a Collaboration diagram it is possible to set message groups like 1.1, 1.2, 1.3 then 2.1, 2.2 etc.

Simple 1,2,3,4,5 is easiest of course.

Let me know the sort of thing you are looking at,
