Bugs and Issues / Transition lines too smart
« on: July 03, 2008, 05:35:01 am »
Transition lines from a super state to a substate seem to have an unruly mind of their own. Often times they become detached from the source (the inner edge of the super state) and they don't tolerate moving the endpoints. Is there a way to just make them stick to where you connect them?


Bugs and Issues / Why is Info Items Conveyed dialog read-only?
« on: June 22, 2008, 09:54:41 am »
I've been happily adding info flows to a composite diagram and specifying the Information Items Conveyed. Unfortunately, the dialog has started coming up in a read-only mode. I have the packages containing the source and destination elements checked out. Any ideas why this is happening?

By read-only I mean that the Add/Remove/OK buttons are inactive.


Bugs and Issues / Ports owned by too many
« on: June 24, 2008, 04:38:58 am »
I have a composite that contains instances of components. The ports of those subcomponents show in the hierarchy as being owned by both the subcomponent and the composite (component containing the instance of the subcomponent). That seems incorrect to me. I am not sure of the consequences of this behavior yet.

Bugs and Issues / List Overrides
« on: May 31, 2008, 02:56:42 am »
I don't understand the list overrides concept in RTF templates. Can anyone point me to description of how this feature works? I've used help but cannot find explicit description of list override.


Bugs and Issues / SQL search and modeldocument
« on: May 29, 2008, 06:50:54 am »
I'm trying to generate documentation usinig an SQL search. The search works fine from the model search but I cannot get its content into the document. Any hints on debugging this? I've tried to make sure that thee fields referenced in the template are produced by the search SELECT statement.


Bugs and Issues / Cannot load p4 locked packages
« on: May 24, 2008, 03:51:44 am »
If a package is configured for single open in perforce and is open for edit, EA will not allow others to load the package. The work-around is to let EA handle the single open restriction and leave p4 configured for multi-open.

The work-around is costing me because developers are not noticing that they have single open files locked when they leave. They look at the p4 change list and don't see the lock icon they've been trained to check for. It proving too easy to overlook the package files (I've done it myself).

This is kind of a nit-picky thing but it is also probably easy to fix.

Bugs and Issues / CSV Export/Import
« on: May 22, 2008, 09:08:15 am »
"Preserve Hierarchy" does not preserve packageA\packageB\element where pacakgeA is the exported package. Neither does it preserve elementA\elementB\elementC. This may be specific to Requirement type elements.

The export appears to work because CSV_KEY and CSV_PARENT_KEY are present. However, the ensuing import results in packageA\elementA\elementB and elementC ends up under packageA.


Bugs and Issues / DAO.Recordset [3167]
« on: May 22, 2008, 05:34:36 am »
When I loaded one of my version controlled packages, and chose force XMI reload, EA pops up:
"DAO.Recordset [3167]

Record deleted"

The particular package was my requirement package so I clicked OK enough times to realize that I'd get to repeat it for each requirement! Using Windows Task Manager to kill EA brought a quicker resolution appears not to have any negative side effects.

I think I can avoid this clearing the model search view first.

Should I be worried about latent side effects?

Seems like this could be handled more gracefully.

Thanks for listening,

Uml Process / Triggers, Events and Signals
« on: October 02, 2010, 03:05:03 pm »
I am confused about Triggers, Events and Signals. Is there a best practice relationship between the three? I could say they are synonyms. I could say that a Trigger is a relationship between an Event and a state transition. I could say that a Signal is a specialization of an Event. I'm missing why the benefit of that distinction. I cannot seem to get it out of my head that both are "occurrences" and don't understand why it helps to have two kinds of occurrence. What consequence should I expect if I ignore "Signal" and just use Event? What might make me regret that decision?

Uml Process / SysML valueType or constraintBlock or both?
« on: October 12, 2010, 11:28:12 am »
Constraint Block specifies the relationship between factors of the quantity and its value. A Value Type just describes the quantity. I think any time a quantity is calculated it would make some sense to create a Constraint Block for it. If the quantity is an input to another constraint, I think I want it in Value Type form. So, if the system computes a quantity the model will have a Constrain Block for it. If it takes the quantity as input the model will have a Value Type for it. If the system does both then the model will have both Constraint Block and Value Type representations for the quantity, right?


Uml Process / Training recommendations
« on: November 01, 2008, 04:07:14 am »
Well, I've finally gotten to the point that it is time to institutionalize modeling in my department's engineering process. Had to convince myself first and EA does enable pratical modeling for software/system development. Having taught myself, (this formum has been a big help) I know it takes significant training to become a competent model-driven developer.

I'd be very happy to get some recommendations on professional trainers.

Our product is a flying robot system (UAS) and includes embedded, real-time elements as well as UI.

Thanks in advance,

Uml Process / Connector tags/continuations
« on: June 15, 2008, 06:24:31 am »
I'd like to show info flows between components without having to snake the line all the way though the diagram.

source---|tag|   <mess of other stuff in drawing> |tag|----destination

Does anyone know how to do this in EA?

I don't know what UML has for this, either.

Thanks, Dan

Uml Process / Use case realizes requirement
« on: April 30, 2008, 10:04:15 am »
When I connect a requirement to a use case using a realization in a diagram EA always makes the use case realize the requirement. Is this a bug or am I thinking about the relationship incorrectly? Use case scenarios illuminate features and requiements so I think of them as being derived from the use case. Perhaps I should be using a trace instead?


Is there a way to generate non-member operations in a model transform?

for example, I want to put something into a C++ PSM that will result in the following after code gen:
Code: [Select]
std::ostream& operation<<(std::ostream& out, foo& foo);The transform engine complains to find "Operation" outside of a Class.


Is there an easy way to copy the behavioral elements of one model to the next? I'm looking for the equivalent of TRANSFORM_CURRENT() on the behavioral elements.
