gmaps-for-apps bower dependency introduces error with upgrade to ember 2.11

[thedig]

Hi there,

I see there is the intention to move off this bower dependency, per issue: https://github.com/Matt-Jensen/ember-cli-g-maps/issues/66

In the meanwhile upgrading to ember 2.11 is now generating an error when attempting to add a marker to a map that is associated with the bower dependency. I'm posting here instead of in the bower package b/c issue #66 gives me the impression this might cease to be supported?

gmaps.js:

  if(options.hasOwnProperty('gm_accessors_')) {
    // Native google.maps.Marker object
    marker = options;
  }

Trace:

Uncaught TypeError: options.hasOwnProperty is not a function

@thedig thanks for publishing this issue. I however cannot reproduce this issue. Can you show me how you declare your marker and g-map?

[thedig]

Sure. We yield it in two parts in the component:

{{#let (hash
         lat=lat
         lng=lng
         infoWindow=(hash content=name)
         visible=true
       )
   as |marker|
}}
  {{yield (hash
    location-autocomplete=(component "g-autocomplete"
      value=site.autocomplete
      on-select=(action 'didUpdatePlace')
      disabled=disabled
    )

    map-component=(component "g-maps"
      mapType="hybrid"
      disableDefaultUI=true
      showScaleControl=false
      showZoomControl=true
      draggable=false
      scrollwheel=false
      name=name
      lat=lat
      lng=lng
      zoom=15
      markers=(array marker)
    )
  )}}
{{/let}}

For the record I attempted on a parallel repo to upgrade to 2.10.1 for comparison. Getting the exact same error this case. (this is an upgrade from a 2.8 lts app which had marker functionality working). I've also verified that the array helper is returning an ember array.

[Matt-Jensen]

@thedig I'm assuming your using ember-composable-helpers helpers for the array helper and ember-let for the let helper? It's really hard to know what data your passing around when I don't know what your helpers are doing.

[thedig]

update - this appears to be a breaking change from upgrading to ^2.10.0 / Glimmer2 (not a bug) - https://github.com/emberjs/ember.js/issues/14489

By design, Ember's hash helper now returns an EmptyObject instead of an Object which lacking the prototype, has no call to hasOwnProperty available

I'll be creating a work-around for now to pass in a regular POJO and awaiting if/when there's an update that accounts for the change.
