Diagrams based on multiple/shared resource [message #1695279]

My current representation is created using a "main" file that uses other files. These files are defined in the main file as "import". When the representation is created i programmatically add these files using Session.addSemanticResource.

Currently when someone adds an import after the creation the session resources does not get updated.
Also In the same session there might be a different representation with the same import.

My question: How do i correctly update the resources of the session?

A trick could be to add the import to the representation but never draw them, this will give the opportunity to call Session.addSemanticResource if the resouce/file was not already added.
But then when deleting a resource from the session i will have to check all representations within the session to check if the resource is used by any representation, this seems kinda heavy on the workload.

Maybe i can point sirius to a method where it described which resources/files are used for a representation.

Using import simply imports a file into your project.
If you want representations on your semantic models, rather than making
code calling Session.addSemanticResource, you can simply use "Add Model"
in contextual menu on your aird file. [1]

To remove a semantic model use "Remove model" on your model under
"Project dependencies" tree node.

Thanks for your response. It helped in some way.

I came to the conclusion that adding the resources is not the problem but rather the way the diagram gets updated.
I am using xtext to write my own language, where it is able to import another file. I will try to explain my problem with a simplified situation below:
--------
MainFile.txt
import secondFile.txt

class Patrick extends Parent
..

secondFile.txt

class Suzanne extends Parent
..
--------
Both files are in the project in the same folder.
When creating a (parent)diagram of the mainfile, this will show Patrick and Suzanne.
When changing the name of Suzanne to Suz in secondFile and saving it, the diagram will show an error. It can no longer find the reference to suzanne.

When saving the mainfile the diagram gets updated correctly, suzanne is now changed to suz. (Saving the mainfile to add changes in an other file is not what i want my users to do)

How can i make sure the diagram gets updated when a referenced resource gets changed?

What do you mean by "not get updated"?

Hi Koen,

It is a Xtext/Sirius integration issue, for this integration we can look
at [1], [2] & [3].
