TypeError: Cannot redefine property When back to same Component by VueRoute

See original GitHub issue

https://github.com/kaorun343/vue-property-decorator/blob/9aecbd28c53927494f51202c3682632bbeffb6ad/src/vue-property-decorator.ts#L106

vue-property-decorator@8.3.0

I have the problem when using the ProvideReactive with VueRouter always get the “TypeError: Cannot redefine property:” when back to the same Component at Second time

I am very sure the component is Destoryed at first time and I am not using the <keeplive /> or something else like that

maybe use the “hasOwnProperty” before defineProperty ?

if (
  !rv[reactiveInjectKey].hasOwnProperty(provide.managedReactive[i])
) {
  Object.defineProperty(
    rv[reactiveInjectKey],
    provide.managedReactive[i],
    {
      enumerable: true,
      get: function() {
        return _this[i];
      },
    },
  );
}

Still broken in 8.4.x Same issue here, however I don’t get any “errors” it just doesn’t work. I use the route re-rendering right now, maybe this is why I dont get an error… But the Provide/Inject feature completely stops to work then. <router-view :key="$route.fullPath" All works fine with 8.2.2 for me.

still broken in 9.0.0 😦

but 8.2.2 works fine

Here is the solution. set inject: [] in Component options

Same here, configuration

export default class List extends Vue {
  @ProvideReactive() newChangeBlip: Blip

Edit: This issue happens in the latest v8.3.0, but works fine in v8.2.1 for now just fix it to that version to have something working 😃
