Flesh out the location-page class to make it more general.

why are you binding something to the location page?

[Dan Beam, 2015/09/29 16:38:55]

i'm pretty sure this binds to this['5'] (which is undefined)

I think what you want is to create:

  properties: {
    readOnly: true,
    type: Object,
    contentSettingsTypes_: {
      COOKIES: 0,
      IMAGES: 1,
      ...
    },
  },

and then

  contentSettingsType="[[contentSettingsType_.COOKIES]]"

Because I envision this to be the page for all categories, not just location,
and I mentioned I didn't want to rename the page yet (to facilitate easier
review).
