Values with prototypes

[thepian]

Intended outcome:

class State {
@observable dashboard:
@computed get widget() { return dashboard.widget; }
}

state.dashboard = { widget: makeWidget() };

function makeWidget() {
return Object.assign(Object.create({ x: 'default', y: 'default' }), { title: '' });
}

I would not expect dashboard.widget.x to be "default"

Actual outcome:

I would not expect dashboard.widget.x to be "default", but it is undefined as the prototype is thrown away.

Would this work for you? https://codesandbox.io/s/angry-ptolemy-yiu6e

I mean you had obvious bug there not binding setWidget, but I don't see any problem after fixing that.

Interesting it seems to work. We must be doing something wrong elsewhere in our codebase.
