Feature in old lib (1.4) not in new subgraph (graph in graph)

[syluna]

Hello,
I was using this feature in version 1.4 (Java 8) of the library.
I am migrating to J17 and taking the opportunity to upgrade to version 19. I couldn't find what this feature has been replaced with and how I could adapt without reusing the code from the old library. I imagine there is a reason, but I don't know enough about EMF to be relevant.
Thank you for your feedback.

Yes, I removed it, as it was never fully implemented / supported.

Do you need this feature back?

I don't want to do this just for me. I get the code from the 1.4 and build extlib to add only subgraph (supergraph is not required for me).

I use subgraph to add "text information" in a parent node and render it in the graph.

Normally additional information (like text) is provided with a domain model.

Yes Ok I try to migrate with this.
