I agree that filtering on tag would be quite useful. We use tags in our requirements, of which there tend to be many.  ;)

General Board / Integrator in Parametric Diagram
« on: July 30, 2011, 03:56:31 am »
Is it possible to create a feedback loop in a parametric diagram.

For example, we have a block called "adder". It has two inputs: A & B with the output of C.

The code would simply be C= A+B

But I want to connect the output C to the input B to essentially remember the last result.

I'm not even sure if EA would support such an operation. But if it did, how would I go about initializing B for the first step through?

General Board / CallOperation Actions

I drag an operation onto an Activity diagram and an CallOperation action is automatically created. But how do I create or link action pins to the variables define in the operation?

I can't use their Visual Compare screen when I do two XMIs from the disk, right?

So I think this is the way I'll have it setup...

We'll have the Master and Replica EAP files in SVN. When doing a baseline, we'll have to follow this manual process:
1) Check all Replica's into SVN
2) Person in charge of the Master updates and synchronizes with all replicas.
3) Check Master into SVN
4) Check Master back out
5) Make Baseline
6) Check Master back in

This gives us a before and after baseline snapshot in the SVN repo. Now I can create a tag or revert my current working copy to anything in the repo. So while EA supports:
- Diff Current with Baseline X
Now I can also support
- Diff Baseline n with Baseline n-1 via SVN and EA
Of course this does not solve
- Diff Baseline n with Baseline X where x > n + 1 OR x < n - 1

In any case, it is complicated.

I'm thinking what I would really like is an Automation interface into the EA compare utility where I would just supply it two XMI files. Then I could pick up the pieces however. But then they would have to rethink their status of "Model only" and "Baseline only" because the phrases imply you are always comparing the current model to something.

I also have the same question (or at least a subset). I have 5 baselines in my project right now. If I say "Show Differences" with baseline 5 selected, it shows me the differences between the Current and 5. If I say "Show Differences" with baseline 4 selected, it shows me the differences between the Current and 4. How do I see the differences between 4 and 5? If you can't do this, what is the point of even allowing more than one baseline?

General Board / SysML Internal - Part
« on: December 11, 2010, 02:27:01 am »
When I tell a "part" on an Internal Block Diagram to turn on the visibility of "Notes", nothing happens. Is this expected behavior? Is it understood that display "notes" on a "part" is not expected of a "part."

General Board / Re: Problems with XMI Export/Import
« on: November 10, 2010, 05:55:49 am »
I have also found that XMI import/export between tools for SysML doesn't work. Particularly, I was attempting between Artisan and EA. They both treat SysML objects so differently, nothing lines up.

Having said that, the reason we went with EA was that, unlike other tools, all the information ACTUALLY IS exported in some format. So we can pickup where the tools leave off. So my suggestion is to parse the XML yourself and script your destination for your desired results (assuming your destination has such extensibility features)

General Board / Default for new diagram
« on: November 10, 2010, 05:51:18 am »
Every diagram I create, I go to Page Setup and change to Landscape. Then I go to Diagram Properties and turn off namespaces and turn on Element Notes (cause I'm doing requirements). It is getting quite repetitious. I want to be able to set this as the default for all new diagrams.

I figured I could do this in the Toolbars->Format Tool, but that doesn't seem to apply to diagrams when I save the "Default Style" after changing these properties.

Where can I do this? I assume I'm just missing it somewhere.

General Board / Traverse from Operation to Activity/Action
« on: September 30, 2010, 05:11:19 am »
Activities and Actions can list an operation in their "behavior" field. Does anyone know how to traverse from the operation to the Activities/Actions that refer to that operation?

General Board / UML Profile - Enumeration - Allow Multiple
« on: September 14, 2010, 10:45:01 pm »
Using as a reference, it is possible to define a tagged value that is limited to an enumeration, but can select multiple values from the enumeration?

ie. color = Yellow, Red

General Board / Copy Ports and Flow Ports
« on: June 17, 2010, 05:39:24 am »
I have two blocks and I have defined a flow port in one of them. I want another port with the exact same definition in the other block, but it seems I'm not allowed to copy "non-elements". Is there any way to copy ports from one block to the next?

General Board / Flow Specification Attribute Direction
« on: June 12, 2010, 01:39:00 am »
How do you set the direction (in/out) of an attribute in a flow specification? I can't seem to figure it out.

Awesome! Thanks.

General Board / Changing Diagram Type
« on: June 10, 2010, 10:14:38 pm »
I have a SysML Use Case diagram with some Use Cases on it. The only real difference form an UML Use Case diagram is that the SysML diagram has a different title format. When I make one of my Use Cases into a Composite Use Case, an UML Use Case diagram is generated, not a SysML Use Case diagram.

I'm looking for a way to take these UML Use Case diagrams and "transform" them into SysML Use Case diagrams so my diagram titles are consistent. Anyone know how to do this?

General Board / Re: What MetaClass for diagram stereotypes?
« on: May 06, 2010, 08:23:26 pm »
Oh, ok, cool. Could I use the same technique to extend a SysML stereotype, like <<block>>?
