General Board / error DAO.Recordset [3197]
« on: March 06, 2018, 01:08:15 am »
I am getting an error that I have not seen before when saving a model and also when exporting a package:

DAO.Recordset [3197]
The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time.
I am using a local EAP file! No-one else is using it and I have only one instance of Sparx EA open..... So what causes this error and how do I resolve it?
Sparx EA version 12.0.1215

General Board / Re: Duplicate attribute error

Ok, Thanks!

The error was in a template indeed. I could not figure out where but I recreated the template and this resolved the issue.

Case closed....  :)

General Board / Duplicate attribute error

When I try to generate a report, I get the following error. I have no idea how to resolve this and I would appreciate any tips!

Code = 0xc00ce554
Source = Line : 157; Char : 136
Error Description = Duplicate attribute

I am using version 12.0.1215 on Windows 10

General Board / Re: Status colors not displayed in Archimate diagrams
« on: February 20, 2018, 06:12:32 am »
I recommend you use an auto color legend. Drop a Legend on the diagram (from the "Common" toolbox), in its properties tick "Apply auto color", set Filter to "Element.Status" and set the fill color or line color as required. These were added at 12.0.1213.

With Archimate elements, legends do not seem to work; colours of elements and connectors are not changed. Is there away around this apart from using straight UML elements?

General Board / Connector titles not shown in HTML report
« on: October 27, 2017, 06:17:54 pm »
When I generate a HTML report from a package, the result does include all the components, attributes and connectors, however the connector titles are not shown!  :-[ . The connector notes are shown but the titles are missing.
Is there a way to create an HTML document template to fix this?

Thanks for your help!

General Board / Re: Diagrams in report cropped! - Resolved
« on: September 05, 2017, 07:11:46 pm »
Glassboy, thanks for the help. But today my problem has magically disappeared without having changed any settings..... Diagrams are now shown in the reports as before. Completely weird behavior, probably due to Windows...  ;). The issue had nothing to do with the documentation template I used and neither with the particular model since it occurred also when I created a new model and used a standard template. It happened also with small diagrams that easily fit on one page; they were cut off at the right and lower side to a size of less than 10x10 cm.
But everything is back to normal now. So the advice to anyone experiencing the same problem is: do nothing and try again tomorrow....:).

General Board / Diagrams in report cropped!
« on: September 04, 2017, 10:33:58 pm »
Suddenly, for no apparent reason, the diagrams in my reports are printed incompletely: They are cropped so that large parts of the diagrams on the right side and underside are invisible! I am not aware of having changed any relevant settings and this is a very serious impediment to my work!

Any help is greatly appreciated!!

I am using the EA Document generator to generate reasonably large documents (50-150 pages).
From one model, I generate two different documents by using two different Model Documents.

The two documents share a number of packages from the model but.... I want those packages placed at different paragraph-levels. This seems not to be possible in a Model Document: all included packages are placed at the top level.

Is there a trick to accomplish what I want? One might think of creating a "package link" that points to the actual package and can itself be included at a different loction in the project browser tree. But I dont think that exists :-(.

Thanks for any suggestions!

General Board / ISA99 Industrial Automation Security and EA
« on: July 17, 2017, 07:04:23 pm »
Has anyone used EA to model industrial automation? Using which meta-model?
I am especially interested in security aspects. I would like to model the various layers, components, requirements and implementations of those components.

Thanks for any tips or suggestions.


General Board / Re: Communicating State Machines
« on: November 29, 2016, 05:20:37 am »
Ok, but I dont see how this solves the problem that a Trigger cannot be invoked from within an Activity (the only element allowed as Effect). EA does not support the use of  a Trigger in an Activity diagram.

Ok Peter, but this doesnt seem to work. An activity can invoke an Action which can be a Send Signal action (right pointing pentagram). But it cannot invoke a Trigger! But a Transition can only be triggered by a Trigger, not by a Send Signal action. So I'm kind of stuck here!

So the problem is that the output of a Transition is of a type (Activity) that cannot be connected to the input of a transition (Trigger).
It is completely unclear to me why Triggers should not be allowed as both input and output of transitions, that would make perfect sense and life very much easier! Or at least allow Triggers in an Activity diagram. Because the strange thing is that on the one hand State Charts and Activity Diagrams are connected via the Effects which can only be Activities, but on the other hand they are completely disconnected and do not allow for each others elements to be mixed in one model. Very annoying!


General Board / Variables in Activity Diagram simulations
« on: November 28, 2016, 01:21:04 am »
Can I use variables in activity diagram simulations? E.g. to use on guards for branching.

If so, how and where do I declare and set these? I find the Sparx documentation unclear on this.

I read about using an Action to set a variable but I dont see how I can do that.

Thanks, Michiel

But Peter, an Action cannot be the effect of a transition in EA.... It is impossible to specify anything else than an Activity! So we still have the problem of linking state machines in a clear way.

@Rodney: There are good reasons foe wanting to use the state of one machine as the guard of another, certainly when creating conceptual models. Such models must be simple and clear. Introducing intermediate variables make diagrams complex and are something you will do when coding the stuff later.

Hi Helmut,

Thanks for these pointers.
Yes, individual state machines can be modeled easily. However I am talking about a (small) set of interacting state machines.
Have you experience with the modelling of interacting state machines?

Two important and very realistic interactions are:
1. The transition of one state machine triggers a transition on another state machine. I cant find a proper way of modeling this in EA: An Effect can be an Activity but it cannot be a Trigger!  I do not see how to model the fact that an Activity results in a Trigger that is input for another state machine.

2. The Guard of one state machine is the State of another state machine. It seems that Guards in EA are nothing more than words without any formal connection to other elements.

So, I will look at the links you sent but I am doubtful if they address my problem...... I definitely hope to be proven otherwise!

Regards, Michiel

General Board / Communicating State Machines
« on: November 04, 2016, 10:25:56 pm »
I am creating models with several state machines that communicate. Communication consists of Triggers that are Effects of Transitions and Guards that correspond to the States of other state machines.

How can I best do this in EA? I have noticed that:
  • It is possible to choose an existing (or ad-hoc created) Activity element as Effect of a Transition
  • It is possible to choose an existing (or ad-hoc created) Trigger element as Trigger of a Transition
However, this is not enough to model relationships between State Machines, because:
  • It is not possible to select an existing Trigger (or list of triggers) as an Effect (via "effect is behaviour")
  • It is not possible to choose an existing State as a Guard (or element in a guard expression)

So, what is your experience, advice or work-around here? Should I choose another tool for my goals?

Thanks, Michiel
