Automatic Refresh for Newly Created Diagrams in Sirius

[hoajie]

Hello Sirius Community,

I hope this message finds you well. I would like to express my gratitude for the support I received previously regarding my work with Sirius modeling.

I have successfully implemented a feature where, upon creating a new diagram titled “Diag on Package 1” using the “Diagram Creation on Package1” option, the diagram correctly displays the corresponding elements under the package. This provides users with a visual indication that the diagram has been created under the package.

However, I am encountering an issue where “Diag on Package 1” is not recognized as a standard Sirius element (like a package or part), and therefore, it does not automatically refresh in the new tree view after creation. Instead, I need to manually refresh the view to see the newly created diagram, as shown in the attached image.

I seem to have encountered a related document before, but I didn't understand it after reading the document. If possible, I hope to get more help from you.

Thank you for your assistance!

Best regards,
hoajie
