General Board / Master is lost, how to create a new Master
« on: August 14, 2011, 06:37:45 pm »
I lost the Master to a Replica. How can I convert one of the Replicas to become the new Master?

General Board / Replica Master does not except Replica
« on: August 09, 2011, 04:51:34 pm »
I am pretty sure that the replica I worked on has been drawn from a certain master. Trying to synchronize the master tells me that the replica does not belong to the set of replicas.

Ok, does not matter much. Now I want to forget that master and like to declare the replica I worked on most as the new master.

Tried several things without success. Is there a knowledge base for this problem?

Kind Regards


General Board / Requirements Traceability
« on: June 20, 2011, 10:40:14 pm »
 I have got two models behaving different and I like to know why:

 It is about Reruirements, Use-Cases, and Components.

 In a diagram I have connected a Use-Case to some Requirements using a Realization association. In another diagram I connected a Component with a Use-Case also using a Realization association.

 In one model I can find the Requirements in the Tagged Values properties of the component, what is a needed service to me. It tells me, that the component is affected by this requirements.

 I did the same in another model but it does not have that trick. Could you think of, what could be different that hinders this Traceability service?

 Kind Regards


p.s. I am using EA 8.0.864

General Board / How to hide Namespaces in all Diagrams?
« on: April 28, 2011, 11:25:19 pm »
I have seen it ones to hide all "::" seperated parts of a name in an element showing only the most specific one, but I can not get it to work again with EA 8.0:

I have a lot of hierarchically sorted interfaces. On Class diagrams that are hosting interfaces as boxes, each name of the interface is preceded by all parent interfaces.

I unchecked "Show Additional Parents" and "Show Namespace" in the properties of diagrams but the huge list of parents still appear in each box.

Any idea what I miss here?

Thank you for help


General Board / image resolution in jpg or png
« on: February 24, 2011, 09:29:20 am »
Is it possible to enhance the quality of images exported with xmi in a pixel format such as jpg or png?

General Board / Generate Diagram Images
« on: January 30, 2011, 01:32:15 am »
exporting XMI you may get all images as JPEG files. That is terrific!

JPEG files contain information about their print size.

Is it possible to change that? E.g. is it possible to go for 120 dots/inch instead of 72 - making the picture smaller but looking better?


General Board / sync glossary

What is the best way to synchronize the glossary with an external file, e.g. xls or csv?

How to get a report of what I have put into Settings/People?

General Board / linking use-cases and components
« on: January 13, 2011, 02:16:36 am »
What is the best practice to express that components shall be aware of certain use-cases?

What I did for a quick solution, is to create a composite diagram for the use case (that is not detailed any further) in order to paste the regarding components into it as Simple Links and surrounded them with a Boundary named "Affected Components".

Is there a better or more-common method?
Will it be possible to get a report, inverting that information: What use-cases affect component XY?

Any comment welcome.

General Board / eap vs. xmi
« on: January 04, 2011, 02:36:17 am »
I exported a milestone of the top-model node as xmi. Than I imported the xmi again in a newly generated project, deleting the default model node. At a first glance it seems to be no difference between the UML content of the newly generated eap file to the older eap version saved for that milestone.

Is everything contained in the new eap file or have I lost something in the conversion eap -> xmi -> eap?

I am thinking about versioning and distributing model milestones as xmi files. Is anything wrong about this approach?


General Board / diagram appearance configuration
« on: December 22, 2010, 02:52:46 am »
Dear long-established EA users

if the appearance of diagrams is configurable could you help me to find the place where information about configuration is available?

The problem at hand: When I drag an interface to a component it manifests as a port of that component. My diagrams get cluttered up from all the stereotypes that comes with the ports name if I name it just like the interface. However, the interface itself shall be bound to a stereotype. It simply shall not show up at ports but just the name of the interface.

Thank you for your kind help.  :)

Bugs and Issues / An error occurded loading the requested project
« on: August 22, 2012, 11:59:29 pm »
Installed EA 9.3 Ultimate as a trial version.

When loading an existing eap file I get the above error with the note: DOA.Database (3159).

The project gets not loaded and EA exits.

Any idea what I did wrong here?

Any help welcome. Rolf

Bugs and Issues / XMI 2.1: same xmi:id to different elements
« on: September 04, 2011, 03:24:45 am »
My generator builds on the XMI export.

It assumes that xmi:id uniquely identifies an item.
Now I am faced with the fact that the exported XMI contains three different and independent lifelines from different sequence diagrams exposing the same xmi:id.

Now I am not able to determine the sender object to a message (using the sendEvent attribute of the message): its one of the three.

Is this an error in exporting or do I think something wrong here?

Any suggestion welcome.


Uml Process / are "generic sequences" allowed in UML?
« on: July 14, 2014, 04:24:05 am »
I am not a specialist in reading superstructure, just a S/W architect in real projects. However, I wonder about the meaning of (I called them) "generic sequences" that I came accross several times:

I understand if a user sends an "add" meassage with a 1 and a 2 as parameters to an object of class "calculator", getting a 3 as a return.

But what does it mean - and I do see this really often - when a user sends an "add" message with two "integers" and get an "integer" as a return?

As there is no further constrain, sending the message "add(1,2)" and get a "4" as a return should be a valid example of that generic sequence. It does not violate add(integer,integer):integer, but obviously it is wrong.

Has someone or can point me to the right words whether such "generic sequences" are part of UML? Whether they are of more value than sketchy remarks (which imho should not appear in a precise technical specification - may be in a clearly marked and non-binding introduction)?

Hope for some enlightening response, Rolf.

Uml Process / Active Class and its State Machine
« on: June 29, 2011, 03:31:45 am »
What is the best practice or the UML specification to express that a certain Active Class behaves as described in a certain State Machine?
