title: PrimeFaces Gmap not rendering (in the simplest example)
body: <p>I have one of the simplest possible pages with a <code>p:gmap</code> on it:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
            "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt;
  &lt;html xmlns="http://www.w3.org/1999/xhtml"
        xmlns:f="http://java.sun.com/jsf/core"
        xmlns:h="http://java.sun.com/jsf/html"
        xmlns:p="http://primefaces.org/ui"&gt;
  
      &lt;f:view&gt;
          &lt;h:head&gt;
              &lt;script src="http://maps.google.com/maps/api/js?sensor=false" type="text/javascript"&gt;&lt;/script&gt;
          &lt;/h:head&gt;
  
          &lt;h:body&gt;
              Map:
              &lt;p:gmap center="49.967109, 8.80198" zoom="15" type="HYBRID" /&gt;
          &lt;/h:body&gt;
      &lt;/f:view&gt;
  
  &lt;/html&gt;
  </code></pre>
  
  <p>However, this shows absolutely nothing under the Map: heading.</p>
  
  <p>I realize that the script connects to some places, but nothing is rendered.</p>
  
  <p><strong>Q:</strong> What's wrong and how do you fix this?</p>
  
  <p>PS: I'm using all versions of PF 3.x ... exchanging them didn't help.</p>
