General Board / SysML Simulation : output of 1.#QNB  value
« on: October 08, 2010, 03:28:00 am »

I'm trying out SysML parametric diagram and EA simulation module for a customer.
I defined the script for my constraint block before creating my parametric diagram.
When I instantiated my constraint block as a constraint property, put my parameters and entered values in the simulation module, it worked ok

I then instantiated my constraint block again to create a second constraint property - for some odd reasons, I'm now getting values with 1.#QNB

any idea what's going on?

General Board / UML Profile for SCRUM ?
« on: March 09, 2010, 06:55:23 pm »

I'm looking at using EA with an agile project involving SCRUM.
Does anyone know if a UML profile is available somewhere to support the SCRUM framework, e.g. product backlog, user stories, features, tasks...


General Board / Tagged values and CSV export/import
« on: March 17, 2010, 01:44:02 am »

I created some tagged values in a number of packages that I'd like to include in my CSV file when running a CSV export.

EA doesn't support this and I was wondering if it could be added?
e.g. export Name, ..., Tagged value 1, Tagged value 2, ..., Tagged value n


General Board / UML Profile and Icons
« on: March 16, 2010, 11:55:02 pm »

I created a UML profile to define a stereotype for a Package and I'd like to specify an icon (so when I create a new element that has this stereotype in EA, it'll be displayed with a different icon).
Unfortunately Sparx only releases the XML files for existing UML profile on their resources page so I cannot see how it's been specified in the source EAP file.

I noticed in the SPEM UML profile (XML file) that the Stereotype tag has the following:

Can anyone indicate how I can specify this in the EAP file that generates the UML profile?


General Board / EA v8: Dynamic Visual Filtering ??
« on: March 11, 2010, 09:57:28 pm »

Can anyone let me know how to use Dynamic Visual Filtering, introduced in v8??
there's nothing in the EA help explaining how to make use of this.


General Board / UML Metamodel as a project?
« on: February 13, 2010, 12:41:49 am »

Is there a way to easily display and navigate through Class diagrams in EA the UML metamodel?

For instance showing the following classes and their associations: Classifier, Element, NameElement, PackageableElement, Relationship, DirectedRelationship, etc.

As this is built in EA, is there an easy way to render it?Or is there any EAP file that can be downloaded, giving visibility over the complete UML metamodel?


General Board / EA 7.5 slow (notes)
« on: January 05, 2010, 11:02:25 pm »

I recently upgraded EA from 7.1 to 7.5 (build 849).
The main issue I have so far is that EA is slower than usual, especially when entering some notes in a Class or other container.

I'm using Windows Vista and whilst I'm typing the description, the cursor changes to a busy mode and it takes some time for the text to be displayed on the screen.

any ideas?


General Board / sequence diagram self message
« on: February 17, 2009, 10:53:18 pm »

In a sequence diagram, I've added a self message to an object specifying that it invokes an operation on itself.
I need to specify operations that are invoked within this operation but I don't seem to be able to add operation calls to other objects within this self message on the sequence diagram

Is there an appropriate way of doing this in EA? I seem to remember that Rational Rose allowed that.


General Board / Subversion and Image clipboard
« on: January 07, 2009, 10:20:27 pm »

I'm working on an EA project shared using SVN version control.
On a class diagram I pasted an image (clipboard).

Other users accessing the shared project cannot see the image.

I'm pretty sure that is due to the fact that the image data is only stored in my own EAP file and not shared via the XML files.
Is there any way to support of image clipboards in a shared environment? Or should this be logged as an enhancement request with Sparx? (I think the image could in this case be stored in a separate file on the SVN repository - the EA diagram would have a reference to this file to display the image)


General Board / UML Profiles for SOA
« on: December 05, 2008, 08:28:50 pm »

I'd like to check the UML profiles and/or EA projects that were used on the following page:

these include:
- MindMapping UML profile
- Zachman

Anybody knows where these can be downloaded?


General Board / EA project on SVN: offline access
« on: December 04, 2008, 08:01:57 pm »

I have an EA project that is working wtih XMI files version controlled on SVN. Each user accessing the EA models have their own EA project file to access the shared XMI files.

It all works well except if I'm not logged on the network and don't have access to the SVN repository: EA tries connecting to the SVN and returns an error message.

What I'd like to do is Check out a package from SVN (corresponds to an XMI file), disconnect from the network and carry out changes. Finally, connect back to the network later and update changes to SVN (Put Latest or Check in.)

I think a way to do this is to set up an EA project that is not version controlled but would update the XMI files, however I'm concerned this could corrupt the project on SVN.

Any recommendation?


General Board / Cannot define a trigger for an accept event action
« on: July 01, 2008, 07:30:23 pm »
In an activity diagram, I need to model an accept event action.
I noticed there are two ways doing it in EA:
- create a Receive Event
- create an Action and change its Advanced properties > Kind to "AcceptEvent"

In either case, I don't have any way to specify one or more Trigger operations.
I noticed that EA considers a receive event (or acceptevent action) to behave like an instance/object where a classifier can be selected so a run state can be specified (populate values in attributes)

I think that instead a receive event should provide a Trigger list that allows selecting any operation from the project which will trigger this event.
If you check the OMG UML Superstructure Figure 11.12 Accept event actions, you will see this is part of UML specs.
It is also implemented in IBM Rational Software modeler.

There is a way round by specifying an action to the trigger operation and creating a dependency "trigger" with the receive event. This is however not ideal.

Can this be updated in the next version of EA?

General Board / Add custom reference to a Requirement
« on: June 27, 2008, 09:37:07 pm »

I need to specify traceability between requirements and use cases.
I noticed that I could do this using Custom References:
- open a use case diagram
- right click on a requirement from the project browser > Add Custom Reference. Select a use case from the list to associate.

Having done this, I'd like to show these references in a Matrix but custom reference is not an available criteria. Actually this custom reference does not appear anywhere unless you open the same use case diagram again and check the requirement's custom reference list.

I know that alternatively I can simply specify a dependency between a requirement and a use case, but I'd like to know if and how I can use Custom References for traceability.

I couldn't find anything from EA Help.


General Board / Rename packages, folders, etc in version control
« on: June 24, 2008, 07:05:02 pm »

I use a project which is configured to work with SVN version control
I have now partitioned it so I have more than a dozen of separate XML files, stored within subfolders which structure is similar to my models and packages in the EA project.

I need to rename one of the packages which contains subpackages/diagrams/elements which are themselves partitioned into separate files.
I could simply rename this package (e.g. \Models\Analysis\ to \Models\Specification) but I'd like to rename the folder and file accordingly as well (in windows explorer: \Models\Analysis\Analysis.xml to \Models\Specification\Specification.xml)

This does not seem to be feasible by only using EA so I tried updating it in TortoiseSVN but it appears to mess things up in EA

Has anyone successfully done it before?


General Board / associate an Action to an operation
« on: May 16, 2008, 06:29:44 pm »
I'm working on an activity diagram which includes calls to interfaces' operations.

I can drag/drop an existing operation from an interface into the activity diagram which results in a new Action element to be generated. Changing the name of this action then displays the up to date name of my interface + operation: (interface :: operation)

If I have a new "blank" action in my activity diagram, how do I associate it with an existing operation so it results in an action as created through an operation drag/drop (described above).
I can't seem to be able to access the association of an action element with an operation to create/update/delete it.
The only thing I found was that in the Action custom properties, "Kind" is set to the value CallOperation

Any help with this will be much appreciated!
