[Ym4r-user] Clusterer generating javascript syntax error

[Joseph Dunn]

Hi all,

I'm using Ym4r with the Clusterer. The GMaps code in my controller
looks something like this:

      # geo is an array of lon/lat points
      session[:gmap] = GMap.new('map_div')
      session[:gmap].control_init(:large_map => true,:map_type => true)
      session[:gmap].center_zoom_init([38.134557,-95.537109],4)
      markers = Array.new
      geodata.each do |geo|
        markers.push(GMarker.new([geo['lon'], geo['lat']],
:info_window => "Hello", :title => "HOYOYO"))
      end
      clusterer = Clusterer.new(markers, :max_visible_markers => 2)
      session[:gmap].overlay_init(clusterer)

Then in my view I'm loading in the requisite javascript libraries,
including clusterer and mapstraction, and then displaying the map with
something like:

<%= session[:gmap].div(:width => 600, :height => 400) %>

However, I get this Javascript error when I view my page:

illegal character
30map.setCenter(new
GLatLng(38.134557,-95.537109),4);map.addOverlay(#<Ym4r::MapstractionPlugin::Clusterer:0x9b3d608>);map.addControl(new
GLargeMapControl());

It seems pretty obvious that a Ruby object reference is somehow
getting inserted into the generated Javascript. Removing the clusterer
lines from my controller solves the problem. Any idea what's going on?

Regards,

Joseph
