General Board / Transitions between States linked with Activities
« on: January 20, 2012, 07:49:17 pm »

On a statechart diagram, is there a way to associate a transition with an activity or a use case in the model?
Let's say that you have states of your system defined in a diagram, and you would like to show the effect of your use cases on the system.

This way you could also trace the effect of a given use case onto a selected statechart


General Board / Reverse code engineering : ssprofiler75 crash
« on: December 22, 2011, 01:49:18 am »

I'm trying to run via the Execution Analyser a workbench instance of a class (imported from C# src code). I'm getting an SSProfiler75.exe error which appears to be EA reverse engineering application.

I only found the following page mentioning this app :

Issue: When attempting to Debug or Profile an application the Debugger/Profiler crashes
Solution: Ensure that SSampler and SSProfiler75 have WinXP as their windows version.

Any idea how can I overcome this issue? I'm running EA v9.2 on Windows 7.


General Board / Use case structured scenarios : activity name
« on: December 16, 2011, 11:25:19 pm »

I created my scenario in a use case, detailling each step though the structured scenario tab. I then generate the activity diagram (which I update/synchronise as I update the scenario, so far so good .
Only down side is that I have to manually rename the name of the activity generate since the name used is meaningless. Instead could EA be tweaked so the activity and the activity diagram are named after the scenario? This would be useful as we specify more and more scenarios under a use case.

Should it be logged as a feature request?


General Board / Components, ports, interfaces & operations on SD
« on: December 15, 2011, 12:18:03 am »

I have a number of components that have several ports, which expose interfaces (themselves having operations defined)
When I put a component onto a sequence diagram, I've got show the embedded elements (ports & interfaces) so I can get the list of available operations.
Problem is that the diagram gets too crowded for the taste of my client, so I'd like to know if there's any way to get all operations that are exposed throughout all interfaces provided by the component on the component itself (without having to define the operation directly onto the component).
In other words, can I make a component inherit from the embedded elements' operations on a SD?


General Board / Reference data and SVN
« on: November 23, 2011, 11:54:40 pm »

Setting up version control for an EA project using SVN often leads to a recurring question about the .EAP file
Currently we shared via XMI files all model elements, packages, and diagrams.
But as far as images, templates, glossary, matrix profiles, audit, and other reference data are concerned, these are stored in the EAP file so one 'ugly' way to apply is to share the EAP other SVN (not ideal since it's a binary file)

Since EA lets us export reference data as XMI, we could alternatively share reference data via XMI exports.

My question is : could or does EA (in recent version) allow to share reference data over XMI files like it knows how to do it with packages/elements/diagram.
A few examples of nice to have features :
- if you want to copy an image, you could via the Resources View run a Check Out on the Images resource to update its content (images could be split over packages like your models) > updating the images on SVN will require an SVN update
- if you want to update the glossary, you could run a check out, etc.


General Board / Components & services model + Physical model
« on: November 10, 2011, 08:44:46 pm »

I defined a components model that stores a number of components
Each component has a number of ports and exposed interfaces
Each interface has a number of operations defined

I need to create a physical model to show a number of servers that will contain some components. Two separate servers can realize the same component : the need is to show all the interfaces that are already defined and maintained in the components model
I tried to use the deployment diagram but the same component cannot be copied twice. If I create a UML part, I cannot show all interfaces on the diagram (only the ports can be show via the embedded elements)
Has anyone got any advice on how to model this? Should I use a component diagram to represent the servers?


General Board / Show all inherited embedded elements ?
« on: November 12, 2011, 01:54:32 am »

I created a set of components with ports and required/provided interfaces in one model.
I needed to allocate these software components onto 'physical components' (e.g. a server) - to do so, I created an instance of the software component under the physical component.
When I instanciate a component and choose to include all embedded elements, all ports & interfaces are shown.
If I update a port or interface, it gets updated fine
BUT if I create a new port, it doesn't show and I have to manually show it

Is there a way to show all embedded elements on a selected object?

General Board / EA 9.1 Simulation with statechart
« on: November 04, 2011, 09:08:41 am »

I opened EA Example project to try the simulation tool.
If find it useful with the activity diagram, but the statechart isn't as straightforward.
- the Pedestrian Crossing statechart executes well but it's full of variables and behaviour written for On Entry and On Exit operations, plus these variables are checked on guard conditions.
If I just want to simulate the statechart depending on the event to move from one state to the other, couldn't EA suggest the possible next moves ? Better, could it react depending on operations called against the class and values on the attributes (as these values could be affected by operations' behaviour)
Considering the Operating States statechart, this model doesn't execute this Play is not defined > how can I fix this according to EA's logic? Does I have to On Entry/exit operations?


General Board / Model Validation bug?
« on: October 13, 2011, 05:50:21 pm »

I tried EA model validation feature and found a bug (even on v9.1) : in the help, it shows as an example  that if you link a class to an activity, it should yield an error within the results of the Model Validation.

However despite enabling all validation rules, and association a class to an activity and a class to an object, no error is returned by EA.
Only an inheritance on the same class yields an error.

Any clue?
Another point : can it be compared with Doors Analyst check feature?


General Board / EA Audit and shared projects
« on: October 12, 2011, 10:50:25 pm »

I enabled EA user security to enable the Auditing.
All models are shared as XMIs via SVN + the EAP file is sometimes committed to SVN when images are added to the project (otherwise we run a Get All Latest to retrieve the latest definition from XMIs)

I wonder how audit logs can be managed in such approach : if each user has its audit log stored in its own EAP, they're lost as far as SVN is concerned. Do we have to force each user to commit an XMI export of its audit log? Or else?
Anyone came across this and can explain a workable solution?


General Board / Sorting elements in the projet browser
« on: October 12, 2011, 10:31:39 pm »

When you define elements (e.g. classes) in your model, they're automatically sorted by alphabetical order in the Project Browser under their package.

You can manually sort them with the Project Browser green arrows and once you've done that, each element that has been moved around has its order manually managed by the user.
Question is : is there any way to re-affect all elements within the package to EA automatic sorting system?

Thanks !

General Board / Swimlanes display bug (ea v7.5)
« on: July 12, 2011, 04:15:24 pm »

I'm using EA v7.5, currently working with activity diagrams that use swimlanes. For some odd reasons, when I open a diagram the widths of all swimlanes is reset to the default one from time to time

Is this a known bug on v7.5 (build 850)?


General Board / Activity diag: control flow to 2 accept events
« on: July 07, 2011, 06:16:25 pm »

I have an activity diagram where I need to represent the following :
My control flow goes to an activity that once completed goes the first event that's occured : 'event 1' or 'event 2'

If I model 2 control flows from the activity to each of the Accept Event Action, will it definitely mean from a UML definition that my control token will go to the first event that's accepted (so if event 1 occurs, my control token goes from there - if event 2 occurs after then, there's no token available)

does it seem correct to you?
Hope it makes sense


General Board / updated objects with activity diagrams
« on: June 28, 2011, 01:12:33 am »

I created an activity diagram where I have an activity that reads properties from 2 objects to update 2 objects (one object being an input to the activity, another object existing before the activity started).
I use a combination of control flow and object flows (object flows being the pre/post cons of my activity)
Is it possible and even suggested to create a dependency or any other type of association (e.g. trace) to associate the same object "obj2" that has changed states before and after the process of an activity ?


Note : I hope the inserted image will be displayed on this post (otherwise the url is

General Board / find a connector in other diagrams
« on: June 10, 2011, 06:25:43 pm »

I'd like to know if there is a way to select a connector between 2 elements (e.g. an association between 2 classes) and find out where this connector is displayed on other diagrams
This is possible for elements and I would find it useful for connectors/associations
