I have this code giving me the strange error message

Uncaught TypeError: Cannot set property 'position' of undefined

This is the inside of a jQuery plugin to show a google map in a popup.
I was using the code somewhere else, where it worked fine - the only difference here seems to be that I'm now using it in a Popup window. Am I missing a scope issue or something?
All the variables like geocoderParams and latlng are filled like they should.
Googling the the error message turned up nothing valuable.

The error message gets fired when the google.maps.Map() is called.

self = $(this)

self.hide()



geocoder = new google.maps.Geocoder

geocoderParams =

  address: self.data('address') || settings.address

  region: settings.region



results = geocoder.geocode geocoderParams, (results, status) ->



if status == google.maps.GeocoderStatus.OK

  latlng = results[0].geometry.location



  mapOptions =

    mapTypeControl: false

    overviewMapControl: false

    zoom: settings.zoomLevel

    center: latlng

    mapTypeId: google.maps.MapTypeId.ROADMAP



  map = new google.maps.Map(self, mapOptions)



self.show()
