TJSDocument not working properly with Module Sub-Types (Data Models)

In Foundry, modules can define a Sub-Types using Data Models.

On Data Models we can also define functions. We can also update the parent document using

this.updateSource()

this.updateSource()

, for example:

export default class MyCustomDataModel extends foundry.abstract.TypeDataModel {
  static defineSchema() {
    const fields = foundry.data.fields;

    return {
      customField: new fields.StringField({}),
    }
  }

  updateField(value) {
    this.updateSource({customField: value});
  }
}

export default class MyCustomDataModel extends foundry.abstract.TypeDataModel {
  static defineSchema() {
    const fields = foundry.data.fields;

    return {
      customField: new fields.StringField({}),
    }
  }

  updateField(value) {
    this.updateSource({customField: value});
  }
}

this however, does not update

TJDocument

TJDocument

and does not update the Store.

Changing the function to updating the parent, however, works:

  updateField(value) {
    this.parent.update({"system.customField": value});
  }

  updateField(value) {
    this.parent.update({"system.customField": value});
  }

From what I can tell, the

DataModel#updateSource

DataModel#updateSource

does not call any Hooks, which might be why.

I think it's worth investigating if there is a way of making

DataModel#updateSource

DataModel#updateSource

triggering the Store in TJSDocument to update.
