New Element Based Edge not working [message #1840824]

Hello lovely community,

I got a problem with the view of my relation. When i create the realtion within my sample it works perfect. But when trying to concat both the source and target port it doesnt do anything within my representation diagram.

Did I go wrong at some point? It would be nice to get a solution for this.
Thank you!

Hi !
I took a look on your metamodel screenshot and it seems that the feature owning the new FunctionExchange is "func_exchanges" and I see "func_exchange" in the properties view of the Create Instance lab::FunctionalExchange.

Hi Florian,

Thank you for your response. I changed it already. But the Tool isnt working either. Maybe it is an issue related to the ports I want to connect via the domain FunctionalExchange? The ports are within a container.

Best regards,
Benny

When you perform Ctrl+space on the type Name field, do you see the FunctionalExchange type?
> The ports are within a container.
Indeed, I do not see all your metamodel but "self" might not be the right context (the eObject owning the func_exchanges feature). In your Change Context expression, you may need to go up to the container that will own the new functionalExchange. If you need, you can test your expressions by using the Interpreter View.

Yes it shows up. But for the Reference Name* it doesnt show me the attribute I got within this domain class.

I already tested everything out. I figured out that the instance of the type FunctionalExchange is not being created but I dont know why...

Thanks

Nothing in the error log?
Are you sure that your context (Change context) is the right one? It should provide the element that owns the feature func_exchanges.
You have to retrieve the parent object that will contain the new exchange. You can start from the source for instance.
If the aql expression becomes too complex, it is possible to define and call your own java service in the Change Context : "aql:source.yourServiceName". See https://www.eclipse.org/sirius/doc/specifier/general/Writing_Queries.html#service_methods.

You can find a good example in the ecoreTools project for instance: https://github.com/eclipse/ecoretools/tree/master/org.eclipse.emf.ecoretools.design

Florian

No the error Log is empty.
But How can I set the context to provide the element that owns the feature func_exchanges when it hasn't been created yet?

The create instance is creating the element which ibasically is the Edge. And this happens after Change Context.

*The problem has been solved.
In the metamodel func_exchanges didn't had a composition to FunctionalExchange with the feature "func_exchanges"

Thank you for your help!
