Automation Interface, Add-Ins and Tools / Re: Model Default Diagram does not start

I know its an old thread, but the following is relevant to something I am working on:

Query usys_system.Default_Diagram. It should contain the guid of your diagram

Which table is that? I can only find tables that begin with t_

I am looking for where the default diagram is set within the repository tables.

Bugs and Issues / Re: EA v 17 xml import links missing

« on: March 03, 2025, 09:29:27 pm »

Thanks for your reply

Yes you are correct in that an export / import via Native works perfectly ... however when the Model Builder (wizard) attempts to import a Native XML file ... nothing is imported 

This Model Builder bug is my main issue.

All the best

Bugs and Issues / EA v 17 xml import links missing

« on: February 18, 2025, 11:29:17 pm »

Hi All

Not sure if anyone else has experienced this bug:

1) Create a small qea repository containing two diagrams, drag one diagram onto the other as a Navigation Cell. All works as expected.
2) Export this repository to xmi v 2.1
3) Create a new qea repository and import the file created in 2) above

The navigation cell does not have it Hyperlink property and hence no longer works as expected 

I have also observed that composite activities and interaction occurrences also loose their links when imported 

Will report as a bug.

I am thinking of a script to fix the import, but cannot find where in the repository the Navigation Cell hyperlinks are stored. I thought it would be t_xref, but does not appear to  be the case. Does anyone know where Navigation Cell hyperlinks are stored?

Thanks
Phil

Automation Interface, Add-Ins and Tools / Re: Adding a legend with values to a diagram via script.

« on: January 03, 2025, 11:20:25 pm »

Hi All

I have achieved this via a Model Based add-in, but as Geert says it is NOT trivial.

In addition to creating a Text element with a subtype = 76, all the legend stuff is located in t_xref with a specific ; delimited string and the RGB values must be stored in EA's own integer values this entry is then cross referenced to the Text element. This requires a new entry per legend to be created in t_xref with each having its own GUID.

Uml Process / Re: [Ask] MDG Technology with 'stereotype PL-architecture::pl_bisapplication'

I presented two videos on how to build MDGs in two EA Global Summits 2020 and 2021, videos also on YouTube.

but again I guess no download links to my EA repositories and any supporting files

Please send me a Personal Message, and I will reply with my personal e-mail, by which you can request my repositories and any supporting files which I can then send to you.

These are both *eapx files but I will migrate them to *qea

Hope this helps

Right-click the Port
Select Advanced | Port Size Customizable

Then you can re-size your port

General Board / Re: How do you get the system of interest into the scenario context in use cases?

« on: October 16, 2024, 09:55:57 pm »

Happy to help.

I have checked my Relationship Matrix in my SysML models and the allocate relationship is set:

source is Block
target is Use Case

So if creating the allocate on a diagram I would quicklink from block to use case and select allocate to

General Board / Re: How do you get the system of interest into the scenario context in use cases?

« on: October 12, 2024, 01:49:27 am »

Not Sure if this will help but in SysML (and I assume similar would work as well), I use the relationship matrix to allocate blocks to use cases using the SysML allocate relationship. (In UML another relationship would work).

Then in the scenario, if the name of a block that is allocated to the Use Case owing that scenario the name is underlined and a hyperlink s created allowing the block to located in the Browser.

Certainly, setting a classifier for the Use Case (Ctrl +L) displays the classifier on the Use Case diagram but does not create an hyperlink in the scenario.

General Board / Re: Generate parts by associations through scripting

« on: October 04, 2024, 05:22:04 pm »

Yes its an embedded element (child of the block).

You will have to create the part element in your script and set its Parent_ID equal to the owning Block Element_ID.

BUT ... the "EA magic" that keeps the part association role name and multiplicity in sync is handled within our good old friend t_xref. The exact details I don't remember, its something like

XrefID,Name,Type,Visibility,Namespace,Requirement,Constraint,Behavior,Partition,Description,Client,Supplier,Link,

{BF1D8DE6-5274-40b0-AD03-7B05C4B6B036},CustomProperties,element property,Public, , , , ,0,@PROP=@NAME=_connectorRef@ENDNAME;@TYPE=string@ENDTYPE;@VALU=<SOURCE>@ENDVALU;@PRMT=@ENDPRMT;@ENDPROP;@PROP=@NAME=isReference@ENDNAME;@TYPE=boolean@ENDTYPE;@VALU=0@ENDVALU;@PRMT=@ENDPRMT;@ENDPROP;,{31294601-A49A-438f-AD49-59030143FD21},{DD41CA65-BE91-481b-919C-17AB0DFDB25D}, ,


In your script you will have to create this entry in t_xref which will involve you creating a new guid for the new t_xref record.

Have fun!

General Board / Re: Class operation parameter types

« on: September 05, 2024, 09:01:00 pm »

Here's what I found in t_xref for a test parameter multiplicity of 1..*

XrefID,Name,Type,Visibility,Namespace,Requirement,Constraint,Behavior,Partition,Description,Client,Supplier,Link,

{D8433594-6904-416a-B247-DA7EC76655B5},CustomProperties,parameter property,Public, , , , ,0,@PROP=@NAME=lower@ENDNAME;@TYPE=Integer@ENDTYPE;@VALU=1@ENDVALU;@PRMT=@ENDPRMT;@ENDPROP;@PROP=@NAME=upper@ENDNAME;@TYPE=UnlimitedNatural@ENDTYPE;@VALU=*@ENDVALU;@PRMT=@ENDPRMT;@ENDPROP;@PROP=@NAME=isUnique@ENDNAME;@TYPE=Boolean@ENDTYPE;@VALU=0@ENDVALU;@PRMT=@ENDPRMT;@ENDPROP;,{4E9BC795-3D5A-4eb7-A916-65648B6F004E},<none>, ,

The multiplicity encapsulated within the Description field is here:

@PROP=@NAME=lower@ENDNAME;@TYPE=Integer@ENDTYPE;@VALU=1@ENDVALU;@PRMT=@ENDPRMT;@ENDPROP;@PROP=@NAME=upper@ENDNAME;@TYPE=UnlimitedNatural@ENDTYPE;@VALU=*@ENDVALU;@PRMT=@ENDPRMT;@ENDPROP;

t_xref.Client is the GUID of the operation parameter

t_xref.Type = parameter property

So

1) Extract required row(s) from t_xref using a SQL Query
2) Split t.xref.Description into its parts using ; storing in a String[]
3) Extract the info you want from the String[] using subscripts (you can work out the value from the above example) ...


Hope this helps

Uml Process / Re: SysML > IBD > connectors: Is there a customary & agreed notation for data rate ?

« on: July 18, 2024, 06:57:17 pm »

One possibility is:

1) Create a Signal element with an attribute rate and default value equal to your rate
2) On the SysML Connector between the parts, use EA's Information Flow Realized and set that to your Signal

The effect is a solid black triangle pointing in the direction of the Connector labelled with the name of your signal (I do not believe however there is a way to show the attribute and initial value)

There is a cheat and name your Signal rate = 1G / sec

Automation Interface, Add-Ins and Tools / Re: JavascriptAddin using session.prompt causes EA to freeze

« on: May 23, 2024, 05:54:22 pm »

Hi

Yes me too!

I developed a Model based Add-in which uses Session.Prompt in addition to Session.Output

Both "freeze" with the "blue circle of death" ... eventually EA will respond to the user click, say OK in the Session.Output.

I have found, that when "freeze" happens, clicking the EA title bar, springs EA back into life and the user interact with the dialog. Not ideal.

As this was for a client, I reverted to write the addin as a conventional C# dll

Automation Interface, Add-Ins and Tools / Re: Access to baseline creation date

« on: May 14, 2024, 10:45:52 pm »

Wot qwerty said plus you may find the following fields useful as well to filter out baselines for other documents stored within the t_document table

t_document.DocID       : which despite its name is actually a GUID (the guid of the actual document entry?)
t_document.ElementID : which despite its name is actually a GUID (the GUID of the baseline?)
t_document.DocName  : the name of the baseline
t_document.DocType    : this has the value Baseline for a Baseline in the t_document table
