Hello Uffe,
thanks for the feedback. I will look into your proposal and see if I can use this approach.

Hi all,
I am currently defining a profile for a communication profile. In this profile I have a stereotype Data object that extends a class. The stereotype has tags such as Object code and Data type, which are enumerations. To be precise Data type is the super set of the entries in the Simple data type and Complex data type enumerations (can I model this using a composition to whole?).
Is there any way to put conditional relations on those tags, such for example if Object code is set to Variable or Array, Data type may be of type Simple data type only and if Object code is set to Record, Data type may be of type Complex data type only.

Allow orthogonal regions in state machine diagrams to be separated alternatively horizontal or vertical.

Suggestions and Requests / State machine internal transitions
« on: March 13, 2012, 05:45:12 pm »
I recently upgraded to EA 9.3 and again was a bit disappointed that state machines still do not support modelling of internal transitions. Am I the only one out there that would need this functionality or what do others think here?

Given that I inquired for an update back in June, it would really be interesting to get an update by Sparx Systems if, and approximately when we can expect an update of the Visual Studio integration. The more that they have introduced the Systems Edition and for the upgrade to this prior purchases of the Visual Studio Integration were not taken into account.
To some extend I got the feeling for being charged for certain functionality twice and not getting much for it.

General Board / Re: Links between project
« on: October 24, 2014, 07:17:51 pm »
With projects, I'm currently just working on a number of independent .eap files that I use to collect ideas. One would collect the concepts for an integrated tool chain development, and other files that I would like to model the individual components of the tool chain. From a min map in the global tool chain project I would have liked to open the separate components projects. Nothing is in version control yet.
But from your feedback, I guess I will use notes in the mind map to refer to the other projects.
Thanks, Martin

General Board / Links between project

Hello, is it possible to create a link from one element in a project to another project? Couldn't find anything in the help nor in the Project Management with UML and Enterprise Architect training documents.
Thanks, Martin

Thanks, that did it.

General Board / «decisionInput»
« on: July 04, 2014, 07:13:28 pm »
We are currently working with activity diagrams and looking for the decision input notational element that we found in the UML superstructure specification section 12.3.22 and also in literature. In EA I have only the note element, but I cannot find a way to the «decisionInput» keyword to a note. Is there any way around this?


General Board / Attributes and Enumerations
« on: May 28, 2013, 12:49:46 am »
in a class I have an attribute a, that in C source code I would like to show up as an uint8_t. I also have an enumeration E of specific values that this attribute can assume.
In my attribute definition I can now specify the type as either uint8_t, or E (the enumeration), but not both. I also would like to set the initial value of the attribute to one of the enumeration values, and limit the attribute values to just one of those enumeration values.
Also when I assign the type to my enumeration type a :E, I can nevertheless enter any value in the Initial Value field, and not, as I had hoped for, just one of the enumeration values. Any way to fix this?

Thanks,  Martin

Ok, thanks, have found it. Set in the Workspace and Commands dialog the Commands to Full.

General Board / Model Validation menu item
« on: May 23, 2013, 11:19:29 pm »
Hi, this has probably been asked before, but I cannot find anything in the forum. In EA9 there was a Project|Model Validation menu item which seems to have disappeared from the default menu system in EA10. The online help however still talks about this menu item. Any hint where I can find it back?

General Board / Re: Class operations and activities
« on: January 29, 2013, 08:57:24 am »
thanks for the help. I had hoped though that there would be a way to avoid making those links manually. The problem I see is that for example in the case of FSA operations that I have to specify name and parameters in the main (general) tab page, but then in the behavior tab could select an activity that possibly models something completely different. I actually would have preferred to be able to select any of the behavioral diagrams directly in the general tab.
Similar, I had hoped that once I define a class operation I could select some kind of 'generate activity from operation' menu item that uses my operation specification including the given parameters that I can use for further modelling as a sort of template.
Concerning the data types, I figured now out that activities support using types that I create in the project, but not those that I import based on a XML file. Operations however allow me to use both.

General Board / Class operations and activities
« on: January 23, 2013, 11:23:31 pm »
I would have some general questions on modeling a class, it's operations, and it's behavior with a FSA.

I define a class and add a state machine to it. I would like to add an operation to the class that I specify in detail in an activity diagram. In 'Fifty Enterprise Architect Tricks' I found that one should create an activity diagram and then drag the class operation onto the diagram. This creates an action within my activity diagram, not an activity itself. In the UML 2.4.1 specification I read 'An action represents a single step within an activity, that is, one that is not further decomposed within the activity. An activity represents a behavior that is composed of individual elements that are actions.' So therefore I assumed that EA should have created an activity instead of an action, and within this activity I describe the operations behavior by further actions.

I also see that for operation parameters I can use custom data types (ISO C99 fixed length types from stdint.h) that I imported with Model Import Reference Data from an XML file, however it appears that I cannot use those types in activity diagrams.

Similar, when in my state diagram, I would like to add an activity (or a class operation) as entry, exit, or do action to a state, which I somehow cannot do. I can however select an activity or a class operation as behavior for a transition.

Are those limitations of Enterprise Architect (I'm using EA10) or do I misunderstand UML concepts here?

Is there any news on internal transition support in EA. I've seen in the release notes of EA10RC1 the following

"Internal Transitions of a State are now shown in the compartment notation"

but did not find any hint in the manual how to handle them.

Go to the Advanced page of a reflexive transition's Properties and set kind=internal

Thanks, that helped a lot. I could not find any description on this in the online help.
