Similar problems are solved in Enterprise Architect 15.

Automation Interface, Add-Ins and Tools / How to simulate object flows in an activity diagram please?

« on: August 29, 2019, 11:43:55 am »

Hi there! When I draw an activity diagram, I linked two actions by an object flow. But the simulation did not work at all for the object flows. I had to add additional control flows to do the simulation succefully. Is it I use the object flows in the wrong way? Or object flows are just not simulated? If object flows cannot be simulated, how about the action pins? Thank you very much!

Bugs and Issues / Re: Activity Parameters not staying-put

« on: June 27, 2019, 05:26:16 pm »

I remember that I have send a bug report some month ago to Sparx.
Let's see if and when it will be fixed.

Hi Peter,

I am really happy to tell you that it is still not fixed yet in the year 2019, more than 3 years after you report the problem!

Bugs and Issues / Re: Problem in creating new a diagram

« on: June 26, 2019, 09:54:15 am »

I've seen errors like the one you describe, but they are always solved by reinstalling (repair install) the software. Did you try it?

Hi, thank you very much for the reply! I tried to reinstall EA several times and I also tried to restart the computer many times. But it did not work for the whole afternoon. After a night's sleep, I tried this morning and it worked well again!!! Maybe EA was tired and needed a rest.

Bugs and Issues / Problem in creating new a diagram

« on: June 25, 2019, 04:54:54 pm »

I am using the trial version of EA on windows 8. It worked very well in the past week. But today it suddenly does not create a new diagram. I can open the project and browse the models. But when I want to add a diagram or element to a package, it becomes dead and I cannot use it. I have to kill it via task-manager. I tried to re-install EA, it did not work at all. What is the problem? Thank you!

Automation Interface, Add-Ins and Tools / Re: Reuse problems in activity diagrams

« on: June 14, 2019, 03:06:12 pm »

You can't and shouldn't reuse actions. An action exists only in the scope of it's activity and is not supposed to be re-used.
The flows from and to actions are properties of these actions.

You can duplicate actions if you want by copy / Ctrl-Shift-V

Hi Geert, Thank you very much for the reply!

Automation Interface, Add-Ins and Tools / Reuse problems in activity diagrams

« on: June 14, 2019, 11:40:28 am »

When I draw an activity diagram, I reused two existing actions by a drag-and-drop. But the control flow between the two actions is copied, too. I do not want to reuse the control flow. But when I deleted the control flow, the original flow was also deleted. Is there a way to figure this out? Thank you very much!

The current version of EA does not provide support for receptions.

You can somewhat create that appearance by creating a stereotyped operation. In SysML blocks must designate whether it makes requests or handles requests for the behavioural features it defines. Hence, you need to set the DirectedFeature stereotype on the operation. Then you can add the additional stereotype 'Signal'. Ideally this keyword should appear after (prov, reqd, or provreqd), but EA cannot do this. Instead the keyword is displayed at the compartment top comma separated like this: «DirectedFeature, signal». Not very nice.

Thank you very much for the reply! It is really helpful.

My last contact with SysML is too long ago, but that looks just like a stereotyped operation. Eventually such an operation is present somewhere in the toolbox. (I would likely just create that by hand)

I don't have SysML installed, but you should find a Port element in the toolbox. Just drag that over a block. Check the tagged values of the Port to set in/out.

Thank you very much for the quick response.

For reception I mean "A reception represents a behavior that a block performs when a client sends a signal that triggers it. Stated formally, a reception is invoked by a signal event." It occupies a compartment in a block.

Hi! I tried to create reception for a SysML block, but I cannot find such an option within EA. How do I add reception to a SysML block? Thank you so much.

- Open the properties of an operation
- Lower right you see tabs: Parameter, Notes, Behavior, ...

There you are :-)

Hi qwerty! Thank you! It is very nice of you!

Hi Volkan,


Well, according to the help it is possible to get code from behavioral models, but if what's described there is any different from, or any improvement on, what's shown in the tutorial I couldn't say.

Personally, I think generating source code from UML models is a fool's errand because UML is a rubbish programming language. So on this topic I'm sitting with qwerty and Peter over here in Camp Curmudgeon. You should come visist! We've got a flag!

Hi Uffe! Many thanks for the reply!

To make a "come out" here, I do not use EA code generation at all, even not to generate the “code framework” (what would work fine from my experience). If I need code level stuff in my model I go the other direction (“reverse engineering”).
Even if generation of algorithm would be possible/good, I would not use that feature because I belief that specifying algorithms to a level of detail that code can be generated is much more effort with UML than writing the code. Further on you have to know what code the code generator generates from your model, what makes the issue quiet complex.
For me UML is a specification language rather than a programming language.
I do not say that code needs to be always written in a text editor (for control functions there exist several good graphical programming environments) but UML for me is not a graphical programming language at all (at least not as long as somebody do not only show me that doing so is not only somehow possible but making sense).

Hi Peter! Thank you very much for the advice! I really appreciate that!
