Package and DiagramLinks creation; c# script

[Piqcked]

I have minors Troubles after trying to generate a package and some diagram links with a c# script .

1) My first issue is about the package stereotype, I used the following commands, but the package sterotype won't change :

Code: [Select]

EA.Package NewPackage = thePackageOutput.Packages.AddNew("APP_Name", "");
NewPackage.StereotypeEx = "SWAppTest";
NewPackage.Update();
My package is created but the Stereotype SWAppTest is not.


2) My second Point is about a specific type of connector, i wanted to link some elements with connectors type of "Aggregation". They are black arrows with a BLACK diamond arrow head. I can create them in E.A. by using the "Aggregation to Whole" command. I have used these commands in my c# script :

Code: [Select]

EA.Connector NewConnector = ElementAPPLICATION.Connectors.AddNew("", "Aggregation");
NewConnector.SupplierID = NewElement.ElementID;
NewConnector.Update();  
But I ended up with another type of arrow, with a WHITE diamond arrow head. But when clicking on it, they do have the type "Aggregation". How do I make the difference between them ?

Thanks !

Re your 1st question:

Stereotype: r/o in the EaPackage but if you need to alter it you must use the EaElement.

(from my Scripting book p. 9)

Re the 2nd: you probably need to modify the role to be composite rather than aggregate,

Tanks for your answers querty.

1) Is a package considered as an element ? That's what you are saying, because sorry but I don't see how your answer is the solution to my question.

2) Composition is not working. It gives a wrong arrow.

Package is a hybrid. Use the EAPackage.Element to modify the stereotype.

I'am sorry but I don't understand, could you give me more details on which syntax I should use ? I don't understand what you mean by using Package.Element. I ve been trying this but it does not work :

Code: [Select]

EA.Package NewPackage = thePackageOutput.Packages.AddNew(APP_Name, "AA");
EA.Element PackageElement = Repository.GetElementByID(NewPackage.PackageID);
PackageElement.StereotypeEx = "SWAppTest";
NewPackage.Update();
ERROR : Cannot find matching ID

Maybe you should read the help first to understand what you are doing?

I now understand as you told me that I must use this syntax :

Code: [Select]

EA.Package NewPackage = thePackageOutput.Packages.AddNew(APP_Name, "AA");
NewPackage.Element.StereotypeEx = "SWAppTest";
NewPackage.Update();
But when I execute my script, i get an error : "Object reference not set to an instance of an object."

I recommend to have a look in my Scripting book.

You need to save the new package first. Only after that you can update its element property.

I used this code :

Code: [Select]

EA.Package NewPackage = thePackageOutput.Packages.AddNew(APP_Name, "AA");
thePackageOutput.Packages.Refresh();
NewPackage.Update();
NewPackage.Element.Stereotype = "SWAppTest";
NewPackage.Update();
And it's working when updating again as you said, thanks !
