 /**

  * This method will generate the resource of this asset when this object has just been newly created.
  * We can't run renderResource() in the constructor since not all dependencies have been injected then. Generating
  * resources lazily in the getResource() method is not feasible either, because getters will be triggered
  * by the validation mechanism on flushing the persistence which will result in undefined behavior.
  *
  * We don't call refresh() here because we only want the resource to be rendered, not all other refresh actions
  * from parent classes being executed.
  *
  * @param integer $initializationCause
