General Board / Connecting between Ports on Parts

« on: November 12, 2009, 08:29:43 am »

When I add a component to a diagram as a Part, its ports only show up in the inherited list. When I make those visible they are read-only which could make sense in some ways. I don't want to modify the inherited port, I want to modify the instance of it on this part (instance of a component). The only modification I want to make, though, is to show that information flows from that port to another part's port in the diagram. I could not see a way to make that happen.

What I did was add a new port to the part. That port is mutable and I was able to connect to similarly created port on another part. In order to keep the relationship to the inherited port I created a Trace from the mutable one to the inherited one. This seems very cumbersome and it still isn't quite what I wanted.

I'm trying to create a schematic like one would create for electrics. All I should have to do is drop Components as Parts and connect them together via the ports. There has to be a good way to do this.

Any ideas?

Thanks,
Dan
P.S. - I have a diagram I can show but I don't know how. If someone can tell me how I'll post it.

General Board / Version controlled packages in DBMS projects

« on: July 01, 2009, 08:24:36 am »

I moved to the Corporate edition to make it easier for a team to work on a project. We had been using the Pro edition with all packages set for version control loaded into private projects. With the Copr edition I expected to use Get Package to load shared models into a DBMS project, check them out and then the whole team could use user locks at the element level. This would be the best of both worlds, shared packages under version control AND the ability for serveral teammates to work on the same package simulatiniously.

What actually happens is that EA notices the package is under external version control will allow only one user to edit a checked-out package. Does anyone know how I can get what want? That is, be able to check out the package and manage user locks on at the item level.

This situation isn't ideal but it is still better than everyone having a private model. At least changes are still seen by everyone as they happen.

Thanks,
Dan

General Board / Multiple stereotypes for Requirement elements

« on: June 20, 2009, 06:58:20 am »

The Stereotype Selector help page shows how to select more than one stereotype for an element. I cannot figure out how to get to the Stereotypes dialog from a Requirement element properties dialog. Anyone know how?

Also, the Requirement dialog presents Type rather than stereotype. I can type in the stereotype but I'd like to get the stereotypes in the pulldown rather than the type list. Any tips?

Thanks,
Dan

General Board / TaggedValues display

« on: December 29, 2008, 12:42:03 pm »

I've added a tag for a bunch of elements. If an element specializes other elements, the Tagged Values view shows the tag and value for the selected element and a list of "from ...". There is one entry in the "from ..." list for each general element specialized by the selected element. It kind of makes sense because the value of the tag is overriding values of the general elements. However, this seems different from other attributes such as Short Description or Alias. Thus, I'm wondering if I have the wrong idea about tags.

Is a tag not the same thing as any other element attribute except that it is a domain-specific addition? In this case, the tag is an external id for the element. Perhaps I've got the wrong idea about how tags can be used.

I'm about to tag about 1000 elements and would like an heads-up if it looks like I've got the wrong idea. If I don't have the wrong idea, why would I care to see the "from ..." information displayed in the Tagged Values view?

Thanks,
Dan

General Board / More than one stereotype

How can I assign multiple stereotypes? Specifically, I want to add <<logical>> to <<block>> on a SysML profile block.

General Board / Model search involving connectors

« on: May 27, 2008, 10:30:20 am »

I've linked a whole bunch of requirements to an artifact. I would like to use model search to list those requirements. Is there a simple way to do it? I fiddled with the SQL search but didn't know what I was doing. Perhaps there is a reference someone could recommend.

Thanks, DanG

General Board / Component frustrations

« on: May 13, 2008, 03:59:28 am »

I'm trying to treat components as sort of super classes. Components offer the concepts necessary to create software ICs as Brad Cox envisioned so many decades ago but I cannot get it to work. I can create a component (IC), add ports (pins), specify the supported or required interfaces (analogous to TTL, CMOS, rise-times, impedence, ...). I can put components into components just like creating macro cells. These things can be represented in class diagrams but with too much detail. All this is exciting and seems right on the cusp of real power.

BUT, when I put components into components the link between object and classifier is lost. Changes to the classifier don't affect the instance. When I make a composite out of a component, I lose the ports in the composite diagram. I cannot show the connection between the parent's ports and the internal component's ports. I'm frustrated because it seems like such a powerful construct but I cannot make it work.

Has anyone had better luck? Am I trying to do something the hard way?

Thanks, Dang
P.S. - I didn't do a very good job of phrase this rant in the form of a question. Sorry.

General Board / Trace list section

« on: May 10, 2008, 12:35:57 pm »

The basic document template has a section for Responsibilities (external requirements) that is driven by the Realisation relationship. I would like to add a similar section to list requirements for Trace. I'm using Trace from requirement to component when the component is only involved and not solely responisble for the requirement. Any hints?

 I can settle for the Connections table but I was hoping for a list including the description like the Responsibilities section has.

Thank you, Dang

General Board / Importing Interface elements

« on: May 03, 2008, 10:57:14 am »

When I import C++ pure virtual classes the element type is Class. Does anyone know an easy way to bring them as Interface elements? I'd settle for an easy way to convert from Class to Interface.

Thanks

Bugs and Issues / Model Transformations Target Package Stuck

« on: June 19, 2013, 07:33:25 am »

Hi,
My model transforms dialog is stuck on an obsolete Target Package and won't forget it. For some time, I was able to delete the target package and the Transformations portion of the dialog would require that I re-select. At some point, the dialog started remembering the target even after I had deleted it. That is, no package by that name in the model but the Model Transforms dialog would still come up with the name. Even when I set a different, and existing, target package the dialog still comes up with the old one. This only happens for one of the transforms I apply to the source model. The other transform still requires a re-select when I delete the target package.

The binding appears to be associated with the classes in the source model. If I create a new package and drag any classes from the old one to the new, the dialog comes up with the transform selected and the target set.

I have changed my transformation chain such that the troublesome transform is not even appropriate for the source model. It is very annoying and confusing to have to un-tic the transform each time I want to apply the other, appropriate transform.

Any ideas?

Thanks,
Dan

Bugs and Issues / Show tags in diagram problem

« on: April 30, 2010, 07:07:50 am »

I created a component diagram and added a component. I then added a tag and value. Next, I used the diagram properties dialog to enable eleement tag visibility. The tag became visible. I selected the element in the diagram and BAM! The element expanded downwards continuously until I deleted it from the diagram. It was slightly comical to watch the vertical slider getting smaller and smaller... I repeated the problem using the context menu feature visibility path as well. The problem has been reported to Sparx.

--- later ---
Just got this from Sparx:
It appears the issue occurs for Packaging Components only but also occurs when enabling other compartments such as Notes and Responsibilities.
Unfortunately we have not found any current workaround (other than not displaying these compartments).

When I use GetPackage the list shows the same package file twice for some packages. Should I be concerned?

Bugs and Issues / Failed to load SCC module

« on: September 17, 2008, 11:21:15 am »

Some of our users are getting "Error while initializing Version Control provider: Failed to load SCC module" when attempting to configure their project for version control. We have a README to guide then throught the process step-by-step and it has been working. Recently, two users are getting the error.

We are using Perforce version 2007.3 (problem also happens with 2008.1). Anyone have pointers for me?

Thanks,

Bugs and Issues / My Checked Out Packages inconsisten with Prog Brow

« on: July 03, 2008, 11:30:41 am »

SCM=perforce
1. Check out a version controlled package
2. Check in the package using perforce UI
3. Exit EA
4. Open model again in EA
5. Project Browser correctly shows package as checked in
6. Run My Checked Out Packages model search
7. Package shows up in query
8. Check out and the undo to resolve the inconsistancy

This is a minor thing but causes confusion for new users and gets in the way of deploying the tool to more developers.

Thanks,
Dan
