Breaks when used in liquid-outlet

[buschtoens]

When the helper is used in a route template that is rendered into a liquid-outlet, two templates are rendered at the same time during a transition. One of these templates inevitably does not match the currently active route hierarchy. If this template then expects a certain task to be resolvable, the assertion fails.

Somehow this only started occurring in Ember 3.13.x. in our app, but I don't want to waste time digging deeper.

IMO usage of this addon should be discouraged anyway. I believe route tasks should be returned as part of the model, like so:

class extends Route {
  @task
  *refresh() { ... }

  model() {
    return {
      someData: ...,
      refresh: this.refresh
    };
  }
}

<button {{on "click" (perform @model.refresh)}}>Refresh</button>
