jMapping V2.0 : not drawing markers in Rails 3 + jQuery-UJS project

i got a problem using jMapping V2.0 in a rails 3 project, it doesn't show up the markers, the plugin uses MarkerManager v3 1.0 to manage the markers, i tested with mozilla and chrome and both doesn't show the markers.. the web page is http://inmoble.heroku.com/mapa so you could take a look at the code, please if someone could point me in the right direction, thanks :开发者_如何学JAVA)

Try moving your included google javascript files to the start of your javascript list of files.

You have:

<script src="/javascripts/map/StyledMarker.js?1291880427" type="text/javascript"></script>
<script src="/javascripts/map/markermanager.js?1291880427" type="text/javascript"></script>
<script src="http://maps.google.com/maps/api/js?v=3.3&sensor=false" type="text/javascript"></script>

Change to:

<script src="http://maps.google.com/maps/api/js?v=3.3&sensor=false" type="text/javascript"></script>
<script src="/javascripts/map/StyledMarker.js?1291880427" type="text/javascript"></script>
<script src="/javascripts/map/markermanager.js?1291880427" type="text/javascript"></script>
