I would like to hear about experiences from engineers who have developed applications using EA's executable state machines and code generation from UML diagrams.  I am looking into it for developing a non-regulated laboratory device that performs real-time process control.

General Board / Entering transitions in statecharts
« on: October 22, 2007, 05:40:23 am »
A standard practice in MDA is to ensure that all events leading to a given state are the same.  It would be nice if, after creating a transition between 2 states, I could select a  trigger from a list and not create a new trigger (that shows up in the Project Browser) each subsequent time I use the trigger name.  The current way, I have to recreate the trigger each time I use it.

Any thoughts on how valid this request is?

General Board / Signals in sequence diagrams
« on: December 03, 2007, 02:09:17 pm »
It appears that, in order to reuse a signal name in a sequence diagram, it must be an operation associated with the receiving object.  The UML Superstructure Spec says "A signal is defined
independently of the classifiers handling the signal occurrence".  

My implementation of signals uses a message class.  All messages are received by the target object with the same operation (DoEvent).  It would be nice to have a list of reusable signals to choose from as well as a list of operations.

Make sense?


General Board / Graduating from newbie

How does one graduate from being a newbie?  I've been using EA for over 2 years on multiple client projects.


General Board / Duplicate code generated
« on: September 01, 2006, 06:21:22 am »
Hi.  I am generating code in C++ at the class and package levels.  Each time I generate, the code is appended to the .cpp and .h files, leaving me the same number of copies of the class (in the code) as the number of times I have generated code.

Any ideas?

General Board / displaying alias of a package
« on: July 17, 2006, 12:49:54 pm »
In a class diagram, I have packages which have alias entries.  I enable the "use alias if available" property of the diagram and the package shows the alias and the package name separated by 2 boxes (ostensibly undisplayable characters).

Any way to get rid of these?


General Board / Element.stereotype in rtf template
« on: June 28, 2006, 02:58:11 pm »
I would like to output an element's stereotype in a rtf file only if the field is not blank.  Is this possible?


General Board / transformation or code generation
« on: January 26, 2006, 02:14:05 pm »
I'm evaluating EA and am wondering how to generate code from state machines.  I don't really see what the transformation step is doing, but it's not generating code.  What I eventually want is a state transition table and an action for each state.


Uml Process / Best way to represent task interaction
« on: June 18, 2008, 11:12:36 pm »
I am developing a real-time embedded system.  It uses 5 tasks and a few message queues to send events (messages) between the tasks.  What is (are?) the preferred way to diagram these interactions.


Uml Process / Concurrent activities in one class
« on: May 15, 2006, 01:14:15 pm »
Hello.  I'm interested in representing one class doing 2 things at the same time in one diagram.  For example, there are 2 client tasks running simultaneously.  One makes a call to my server class which can take some time to complete.  Meanwhile, another client (in another task) can request a bit of information while the first request is being handled.

This does not seem to be supported in interaction diagrams.
Is there a UML way to do this and is it supported in EA?
