[OpenLayers-Users] Trouble with an example of openlayers!!!

Mon Jul 27 12:36:10 EDT 2009

Hi to everyone. 
I'm new in the world of openlayers. I've been working with it for a few days, reading some documentation and specially using the examples found in the official page of openlayers. Everything fine until I tried to use this example: 

http://openlayers.org/dev/examples/getfeatureinfo-popup.html

My project involves do something just like that, but when I use this example locally in my pc (downloaded and modified only in the url of openlayer script) the popups of the features aren't shown and I get this error code:

Error: uncaught exception: [Exception... "Access to restricted URI denied"  code: "1012" nsresult: "0x805303f4 (NS_ERROR_DOM_BAD_URI)"  location: "http://openlayers.org/api/OpenLayers.js Line: 1078"]
Archivo de origen: http://openlayers.org/api/OpenLayers.js

This is the code:

        var highlight = new OpenLayers.Layer.Vector("Highlighted Features", {

        map.addLayers([political, roads, cities, water, highlight]);
