title: Unsafe JavaScript attempt to access frame with URL
body: <p>I have a page with an Iframe and a Javascript from Iframe that access to a function of parent frame. The pages are on the same server (it's not cross domain scripting), I'haven't any problem with FF and IE but when I use it on Chrome I have the message below.</p>
  
  <blockquote>
    <p>Unsafe JavaScript attempt to access frame with URL 
    <a href="http://samedomain:51700/irj/servlet/prt/portal/prtroot/CRMApp73.StoricoApp">http://samedomain:51700/irj/servlet/prt/portal/prtroot/CRMApp73.StoricoApp</a>
    from frame with URL 
    <a href="http://samedomain:51700/irj/servlet/prt/portal/prtroot/CRMApp73.CRMOProxy">http://samedomain:51700/irj/servlet/prt/portal/prtroot/CRMApp73.CRMOProxy</a>.
    Domains, protocols and ports must match.</p>
  </blockquote>
  
  <p>How can I solve this issue? I search by google since 4 hours. I hope someone can help me.</p>
  
  <p>EDIT: code</p>
  
  <p>This is the JavaScript in the iframe page. This JavaScript call a parent frame Javascript function "setUfficioPostale". This is the point where Chrome give me "Unsafe Access..." error.</p>
  
  <pre><code>&lt;script&gt;
      window.parent.setUfficioPostale(map);
  &lt;/script&gt;
  </code></pre>
  
  <p>This is the Javascript in the parent frame for form submitting. This is for sending hidden form with hidden params to a page loaded in iframe.</p>
  
  <pre><code>function onAltroUfficioClick(){
      document.getElementById("hiddenParams").submit();
      $('#framePosteMaps').show();
  }
  </code></pre>
  
  <p>This is the iframe definition in the parent page.</p>
  
  <pre><code>&lt;iframe id="framePosteMaps" scrolling="no" name="framePosteMaps"&gt;&lt;/iframe&gt;
  </code></pre>
  
  <p>This is the form with target attribute to send parameters to iframe page.</p>
  
  <pre><code>&lt;form id="hiddenParams" target="framePosteMaps" action="http://samedomain:51700/irj/servlet/prt/portal/prtroot/TestFrameRC.SimPerProxy" method="POST"&gt;
      &lt;input type="hidden" name="distanza" value="10"&gt;
      &lt;input type="hidden" name="cliente" value="Retail"&gt;
      ....................
  &lt;/form&gt;
  </code></pre>
