General Board / Re: Not being able to type a FlowProperty with a Signal

« Last post by EAButNotForGames on August 20, 2025, 06:09:18 pm »

In the properties window of the FlowProperty, under Type.

This worked in older EA Versions. I used it through Version 16. And I am pretty sure it worked in the release version of 17.

I was trying to model the signal flow in an IBD. And while creating the InterfaceBlocks I noticed this bug.
Based on the SysML specification: "A FlowProperty shall be typed by a ValueType, Block, or Signal."
Value Type and Block still works though.

Bugs and Issues / Re: SparxEA SQLServer Repository MFA Authentication - ActiveDirectoryInteractive

« Last post by Modesto Vega on August 20, 2025, 06:08:26 pm »

I don't know. Our users are already logged in into windows with the correct credentials, so PCS doesn't need to log them in (or use MFA)
WebEA is a different case althogether.

Geert

It is the same for our users with some very awkward authentication exceptions that have been reported to Sparx Systems.

WebEA is the main reason for the question.

Having said that, since Microsoft implemented MFA for using desktop apps, even when logged in using the right credentials, I have noticed a dilution of the boundaries between 1) using a Windows AD account to log into a laptop attached to a domain, 2) Sparx EA (plus PCS) using that account, 3) SSO, and 4) MFA; the boundary is at times so diluted that MFA is almost always required or, to use other words, those 4 things are conflated.

This is of no help to you but I can confirm it does work in 1625 and there's nothing in the release history to suggest that this functionality has been altered in any way since then.
Sorry I don't have 1710 to hand to help you out further.

Out of interest, how are you trying to apply the signal type to the flowproperty?

General Board / Re: ChatGPT enabled models?

« Last post by TomO on August 20, 2025, 09:01:18 am »

Hi All,
Indeed LLM support has been in EA since version 17.1 and it recently got a boost in build 1713.

Configuration:

• To configure it you need to be in a model with security enabled.
• After you have logged in to the model go to Settings -> Options -> Collaboration
• In build 1713 you will see a "ChatGPT Configuration" area, this will be expanded to other LLMs in coming builds.
• Enter in the required details: Service Address, API Key, Model, Group.
• And you will be up and running.

Once enabled you can then have chats and discussions with the LLM, we have a video that demos this off:
https://youtu.be/vPcu3Sui2ZY

The main features are:

• Chats are good for one off questions with no conversation memory - good for a quick question
• Discussions have full conversation memory so you can have a discussion with the LLM
• A workbench to move the result of the LLM into a workable area (Create elements, push text to notes, create glossary items and etc)
  
• #diagram# and #element# keywords to send the LLM the currently active diagram or currently selected element so you can ask specific questions of the LLM

*A few main caveats:
- We are actively working on this feature, so dialogs and functionality will change.
- The LLM configuration is a model level config meaning a) you will need to configure it for each model you want to work on and b) if you share this model with others they will also be able to make queries to your LLM API.

General Board / Re: Backward and forward compatibility between versions of Sparx EA and PCS

« Last post by Geert Bellekens on August 19, 2025, 06:43:45 pm »

In short, it is compatible but not supported.

The question here is, what does that mean?
How is "supported" different from "not supported"?

Official Sparx Systems response is below.

Please note that the latest version of Enterprise Architect (EA) is compatible with Pro Cloud Server (PCS) version 5.x.

However, we cannot guarantee that all functions will work correctly in this combination.

Therefore, we highly recommend upgrading to the latest versions to take advantage of enhanced features and bug fixes.

[..]

Kindly note that Enterprise Architect v17.x and Pro Cloud Server v6.x are the officially supported versions. Previous versions are no longer officially supported.

In short, it is compatible but not supported.

Hi Shimon,

Thank you for your reply. I am glad to hear that it works well with the latest installer.

As you guessed, currently some limited types and the profile-based types (such as ArchiMate) are supported. Please read the description of the tool to know which types are supported. This is because currently I think it is not easy for the LLMs to specify the correct Enterprise Architect element types. (For example, 'UseCase' is okay but 'Use Case' is NG).

About the Sequence diagrams, currently the MCP server supports exporting information from Sequence diagrams, to be able to generate source codes etc. from the Sequece diagrams. The server exports information about fragments too, so now I think it is enough to generate source codes from the diagrams.
Unfortunately, currently generating the Sequence diagrams are not supported, this is very difficult.

I have checked that the MCP server and Claude/ChatGPT on VSCode can generate source codes from the Sequence, StateMachine and Activity diagrams.

p.s.
Please send me the error information directly. I am the only one interested in the details.

Hi,
It indeed works as you said.
There are some SQL errors when Claude reads the model. Do you want me to post them here (or send them to you)?

I tried creating Use Cases and found that I cannot. Claude created classes ( and later Requirements, after I requested that). I assume that this is by design.

As there exist already some add-ins ( that I did not experiment with, yet) to create sequence diagrams from text, via plantUML, I assume that Claude would have no problem creating sequence diagram from log files of a running program. This opens the possibility of Reverse Engineering ( to be more exact, creating a Design Model from)  a/an existing Software Project.
Are you planning to extend the abilities of the MCP to include sequence diagrams ( and / or Statecharts)?
These possibilities are really exiting.
Sincerely,
Shimon
