Property 'root' is protected and only accessible within class 'DefaultModelState' and its subclasses.

[csamarchi]

I am following the Source Model structure for a Node server GLSP vscode extension. I have included all these files verbatim. I am getting the following error at this point in my code when building:

Property 'root' is protected and only accessible within class 'DefaultModelState' and its subclasses.

I have tried replacing protected with public and still nothing.

I understand private/protected properties are only allowed within their class or subclass, but I am injecting the ModuleModelState part class within this file. I'm not sure how to move forward. Also unsure where "root" comes from exactly.

Any help is much appreciated. Thanks

Hi @csamarchi,
The ModelState interface offers a dedicated updateModelRoot method that you can use here:

-      this.modelState.root= GGraph.builder().id(module.id).addChildren(inputNodes).build();
+      this.modelState.updateRoot( GGraph.builder().id(module.id).addChildren(inputNodes).build());

If you are looking for an example please have a look at the official documentation.
There you can find a code snippet that demonstrates how to create your own custom ModelFactory:

@injectable()
export class MyModelFactory implements GModelFactory {
  @inject(MyModelState)
  protected modelState: MyModelState;

  createModel(): void {
    const entities = this.modelState.getModel().getEntities();

    const entityNodes = entities.map((entity) =>
      new GNodeBuilder(GNode)
        .id("node:entity")
        .layout("vbox")
        .add(new GLabelBuilder(GLabel).text(entity.name).build())
        .build()
    );

    const newModel = new GGraphBuilder(GGraph)
      .id("entity-graph")
      .addChildren(...entityNodes)
      .build();

    this.modelState.updateRoot(newModel);
  }
}```

Thank you! That fixed it.

On the same subject of getting my Source Model to work, I am running into one more issue in my storage.ts file. I copied the example linked in the official documentation here.

I am getting the error error TS2740: Type '{ id: any; inputs: never[]; duration: number; taskType: string; name: string; references: string; description: string; source: string; }' is missing the following properties from type 'Module': type, [GLayoutContainer], position, size, and 6 more.

On this section of code:

I have tried to specify all of the required properties on the object and tried marking the properties as optional with a '?' after the property. Both routes don't work. Do you have a solution?

Any help is appreciated. Thanks
