Call behaviours from sequence diagrams in separate package, .net C#

[dambsst_gmail]

Hello Everyone,

I have created and modified the add-in from http://blog.sparxsystems.eu/2015/06/do-you-miss-something-in-ea's-code-generator/ in order to solve the problem when calling an operation of a class which is outside the current package.

The message from the code template is "Associated behavior not found within the package!!" , I am sure you have already seen it 

If I move this package to the same package than my calling class, it works perfectly.



So basically, I have reversed engineer the mscorlib.dll from microsoft inside a package called "framework" , so that I can access the .net framework inside EA.

I have another package called "system" with a class and an operation defined by a behaviour which interact with the class system.console from .net framework.

I want to call the operation WriteLine("") , but it complains that it can not find it within the package. If I nest the "framework" package under "system", everything is perfect it ends up with Console.WriteLine("Hello");

So what I have done so far: I have modified the C# code template "Action Call" and replace the section:

Code: [Select]

%if $sBehName == ""%
/*Warning: $sActionName - Associated behavior not found within the package!!*/
%endTemplate%

with

Code: [Select]

%if $sBehName == ""%
$sBehName = %EXEC_ADD_IN("EA_DCGB_ADDIN", "MyEASL_GET", "element", $GUID, "Name")%
%endIf%

Using visual studio and the debugger, I succeeded to find a matching object with same GUID, it is an object of type "Connector". The problem is now that I can not find any way to reach its operation to return its name.... and I am not even sure I should do this.

By using Bellekens Enterprise Architect Toolpack at https://bellekens.com/product/bellekens-enterprise-architect-toolpack/ , when I perform a search by GUID it finds the connector and the matching operation. But I don't succeed.

If someone has found how to do it I would really appreciate to receive a hint or a solution because I am a bit confused with the SDK, how the EA objects are constructed and how the behaviours are interpreted by the code generator.

Many Thanks,

If you use the EA Navigator, and you select the message on the sequence diagram you should be able to select the operation.
It is based on a tagged value on the message that holds the guid of the operation.

Hello Geert,

Thanks a lot!! But like, a lots of lots 

You lead me to the good way with the taggedvalue, now I will always inspect them because they hold information and even if they are not displayed in Enterprise Architect we can see them using InteropEA.dll

Using EA navigator yes I could view and select the operation, but not more, I didn't know where this information is stored and yes it is a  tag value called "operation_guid" ! 

So I tried to access it using the code tempate only but without success:

Code: [Select]

%if connectorTag:"operation_guid" != ""%
...
%endIf

%if connectorDestTag:"operation_guid" != ""%
...
%endIf

%if connectorDestElemTag:"operation_guid" != ""%
...
%endIf

But without success.

So I finally modified your add-in:

Code: [Select]

switch (what)
                {
                    case "connector":
                        EA.Connector conn = rep.GetConnectorByGuid(owner);
                        if (conn != null)
                        {
                            foreach (EA.ConnectorTag tag in conn.TaggedValues)
                            {
                                if (tag.Name == "operation_guid")
                                {
                                    EA.Method method = rep.GetMethodByGuid(tag.Value);
                                    result = method != null ? method.Name : "";
                                    break;
                                }
                            }
                        }
                        break;

                    case "element":
                        Element ownerElement = rep.GetElementByGuid(owner);
                        result = ownerElement != null ? GetElementProperty(rep, ownerElement, name) : "";
                        break;
....

and the c# code template of "Action Call":

Code: [Select]

%if $sBehName == ""%
$COMMENT = "Maybe it is in another package, it's not reachable"
$COMMENT = "If the $GUID is a \"connector\", try to get its \"operation_guid\" taggedvalue"
$sBehName = %EXEC_ADD_IN("EA_DCGB_ADDIN", "MyEASL_GET", "connector", $GUID, "Name")%
%if $sBehName == ""%
%endTemplate%
%endIf%

Now everything's fine, not completly clear I will certainly faced other issues later but I hope I will learn from your source at

I have 15 days left on my trial, I will go forward and fill my custom MDG Technology with lots of C#.

Thanks again!
Best support ever! (especially since we are sunday morning  )
