Ah, found it! Thanks!

General Board / Setting the type of Activity Parameter

« on: May 12, 2025, 09:22:40 pm »

On addition of an Activity Parameter to an Activity, the default type of the parameter is an Integer. According to https://sparxsystems.com/enterprise_architect_user_guide/17.0/modeling_languages/activityparameternodes.html the type of the parameter can be changed via the 'Parameter' tab of the 'Properties' dialog. That tab seems to be missing from the dialog however, or am I overlooking something? How can the type of an Activity Parameter be changed? I'm using EA 17.1 build 1710.

General Board / SysML MDG technology in version 13?

« on: February 25, 2020, 10:16:10 pm »

According to this page SysML should be an included MDG product in the EA Corporate edition. Our company is running the Corporate Edition version 13.0.1309 and that version seems to be lacking SysML support. SysML is not included in the list of MDG Technologies.

How do I enable SysML support in this Edition/version?

I just registered a support request. (That took some time as I had an issue with share-it in renewing my subscription.)

General Board / Add trigger directly to element

« on: January 05, 2013, 09:24:53 pm »

In EA version 9.2 I was able to add a Trigger directly to an element by selecting Add Element in the  Project Browser package context menu.  I thereto had to select <default> as the active toolset and then I was able to select a Trigger as the type of the new element.

In version 10 the default toolset seems to be UML::Class and there seems to be no way to select all available UML types. Furthermore, the Trigger type is - as far as I can see - no part of any toolset.

So, how do I add a trigger directly to an element in version 10?

General Board / List of values for tagged value?

« on: August 12, 2007, 08:10:48 am »

Hi,

In a profile I created a stereotyped class S and an enumeration E with three possible values: 1, 2 and 3. To the stereotype S I added an attribute A with type E.

I then created a model based on this profile and added an instance s of the stereoptype S. The attribute A shows up as a tagged value A of the instance s as expected. In the pull-down list for the values I can select a value for the tagged value.

Now, when I appply a multiplicity (e.g. [0..5]) to attribute A in the profile, indicating that A comprises a numer of enumerations E, and instantiate the stereotype it seems that this multiplicity does not apply to the tagged value A. Is there a way to apply this multiplicity to tagged values?

In other words: is it possible to select multiple values for a tagged value in the drop-down list?

General Board / Package indication in class generalization

« on: October 13, 2006, 06:39:44 am »

Hi,

When a class inherites from a number of parent classes each having an attribute, the inheritated class can be shown with the parent classes indicated in the attributes compartment. However, when the parent classes have the same name and are in different packages, the attribute compartment of the inherited class just shows the class name (as shown in the figure below).



Is it possible in EA to also show the package of the classes inherited from (i.e. "Package1::Class1" and "Package2::Class1" instead of just "::Class1") as in the custom (Visio) drawing in the right of the image?

Regards,

Jos

General Board / Re: cool class diagram feature: how'd I do it?

« on: March 31, 2006, 01:40:54 am »

Did you by any chance create a generalization relationship from the concrete class to the interface class (i.e. the concrete class inherits from the interface class)?

This relationship can only be drawn when "strict UML syntax" is off but then produces the result you described?

Jos

General Board / Re: Specialization of stereotypes in profile

« on: February 16, 2006, 11:01:51 am »

Hi Olaf,

Thank you for your extensive reaction.  I will file bug reports for the problems I noticed using profiles.

And you are right, I was trying to do something odd, defining a profile for EMF ecore by simply copying most of the ecore metamodel in the profile. I now abonded that approach for a more simple version of the profile.

I will investigate the use of "MDG Technology" files. Thank you for pointing me in that direction.

Regards,

Jos

General Board / Re: Specialization of stereotypes in profile

Actually I wasn't aware that I was doing something complicated  

I simply draw the three stereotype classes and draw the generalization relationships on the profile class diagram using the icons from the profile toolbox. Seemed nothing special to me...

Perhaps this is a version issue? I'm using build 786. I'm under the impression that the profile support is not yet matured. I cannot get the Synch Tagged Values to work and when I try to draw a profile connector to a diagram as described in paragraph 6.6.2.4 of the User Guide, EA actually crashes!

I'm not yet sure I will use this profile support at all...

General Board / Specialization of stereotypes in profile

« on: February 12, 2006, 08:54:38 am »

Hi,

When trying to create a profile I noticed the following behaviour. In the profile I created three stereotypes, "Association", "EReference" and "EStructuralFeature". Association is a specialization of EReference which on its turn is a specialization of EStructuralFeature.

When I apply the stereotype "Association" to an element the attributes of "Association" and "EReference" turn up as tagged values of the element; the attributes of "EStructuralFeature" however don't. Is this a feature or a bug?

General Board / Re: UML 2.0 XMI Export

« on: November 12, 2005, 03:24:43 am »

The subject of XMI export doesn't seem to be very popular as few people react to topics of this kind...

This being the case I drew my own conclusions and wrote a stylesheet to transform EA's XMI format to - in my case - EMF ecore format. This isn't too hard to do, although writing a stylesheet for a complete UML2 model (including all diagrams) probably would take some time.

General Board / Setting font of connector labels?

« on: January 21, 2006, 03:21:00 am »

Hi,

The context menu of elements contains an option to change the font used for the element (Appearance/Set Font). Is there a similar option for the label on the connectors?

The context menu of the connector contains an Appearnce menu-item but that allows one just to set line color and thickness; the context menu of the label on the connector allows one set the label color and mark the label bold, but no option to set the font. So how can I change the font used for connector labels?

Regards,

Jos

General Board / XMI export to UML2

« on: October 15, 2005, 03:11:18 am »

Hi,

As I wanted to be able to import a State Transition Diagram from EA to Eclipse UML2 I delved into XSLT and wrote a simple stylesheet to transform parts of an EA XMI file to a .UML2 file. Now two questions arose:

1. I based my stylesheet on EA's XMI 1.1 as I read in this forum that that version should be EA's "native format". Is that a wise decision or should I  use XMI 1.2?

2. Is it possible to deduce from EA's XMI 1.1 file in which region (concurrent substate) a state is in? The only region information the XMI file seems to contain is a tagged value $ea_xref_property for the state containing the regions. The fields in this tag however do not contain the relevant information?

Best regards,

Jos

General Board / Linking activity diagrams

« on: June 18, 2004, 07:17:11 am »

Hi,

In EA I can create an "activity overview diagram" which  shows the relation between several activity diagrams. I draw this diagram by dropping the activity diagrams as a diagram reference from the project browser onto the overview diagram and linking them with control flows.

In the overview diagram multiple control flows from different sources will lead to an activity diagram and multiple control flows will leave an activity diagram to different targets. These different control flows obviously have to be present in the nested activity diagram too.

Is there a way to express the linkage between the control flows in the overview diagram to the control flows in the nested diagram (and vice versa), something like the gate concept in interaction diagrams or the entry and exit points in state diagrams?

Any suggestion is welcomed,

Jos Fries
