Having a Computed Property (CP) which depends on a oneWay CP doesn't work

Here is a twiddle which demonstrates the issue https://ember-twiddle.com/1934386ad97e960cac37b36cf0068847?openFiles=templates.my-route.hbs%2C&route=%2Fmy-route

The controller has three CPs,

customRoutingType: oneWay('model.customRoutingType'),
isFixedRouted: equal('customRoutingType', 'fixed').volatile().readOnly(),
isDynamicRouted: equal('customRoutingType', 'dynamic').volatile().readOnly()

customRoutingType can take the values fixed & dynamic based on which radio button you click when you visit the my-route route in the twiddle

The route template displays the state of the three values. customRoutingType updates as you toggle the radio buttons, but the other dependent CPs do not.

It also is correctly explained in the API specification:

It also does not automatically fire any change events. You must manually notify any changes if you want to observe this property.

Dependency keys have no effect on volatile properties as they are for cache invalidation and notification when cached value is invalidated.

I guess this can be safely withdrawn then 😃 Thanks everyone for the explanations
