Update CustomVariable config with SceneDataTransformer result

[LarsStegman]

Hello,

I want to use the result of a SceneDataTransformer and set it as the possible values of a CustomVariable. How should I approach this? Right now I have:

1. Variable q with query ""
2. SceneQueryRunner x with the raw data query.
3. SceneDataTransformer y with its $data property set to x
4. activationHandler on y that subscribes to y state. In the subscription handler I then call q.setState({query: yResult}). This unfortunately does not work. As the scene does not make use of the result. The subscription handler is called and I can print the result in the console.
