Isn't a component resource already dependent on its child resources? Just make sure that their parent is the component resource, and it should work, I think.

Though the constructor will return immediately, any `Apply` for things like its _Id_ won't happen until the child resources' _Id_'s are available.

What <@U012UJTT55M> said. For clarity's sake I think what you're missing is the:
```var resourceA = new A(
    ...,
    customResourceOptions: {
        parent: this,
    });```
Which is what explicitly forms that relationship.

So you have to set the parent explicitly. Will try, thanks.
