title: XML Parsing Error: no element found Location: moz-nullprincipal (not strong with ajax)
body: <p>I know this question has been asked many times and from what i have researched on this error it appears that it happens because cross domain ajax is only allowed for JSONP, not XML. But i am having trouble finding where this call is being made so I can't exactly find where the problem is. Everything is working fine until I added the following code</p>
  
  <pre><code>@EventListener(targets="licensingStatus", events="onchange")
  public void onLicenseStatusChange(IRequestCycle cycle){
      cycle.getResponseBuilder().updateComponent("licenceAuthRequiredDiv");
  }
  </code></pre>
  
  <p>This is the component that the above code is updating</p>
  
  <pre><code>&lt;div jwcid="licenceAuthRequiredDiv@Any"&gt;
        &lt;span jwcid="@If" condition="ognl:company.licensingStatus == @com.fexco.wuams.valueobject.LicensingStatus@Pass &amp;&amp; inApprovalMode()" renderTag="literal:false"&gt;
              &lt;input jwcid="licensingApprovalDateRequired@DatePicker" disabled="ognl:disabled || isLicensingApprovalDateDisabled()"
              value="ognl:company.licensingApprovalDate" displayName="message:company.licensingApprovalDate" validators="validators:maxDateToday,required" /&gt;
       &lt;/span&gt;
       &lt;span jwcid="@Else" renderTag="literal:false"&gt;
              &lt;input jwcid="licensingApprovalDate@DatePicker" disabled="ognl:disabled || isLicensingApprovalDateDisabled()"
              value="ognl:company.licensingApprovalDate" displayName="message:company.licensingApprovalDate" validators="validators:maxDateToday" /&gt;
        &lt;/span&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Using Firebug, when this is hit and moves through and a POST and GET requests are made and I get the following on the POST: <code>302 Moved Temporarily</code> and the GET request just hangs with the following: <code>XML Parsing Error: no element found Location: moz-nullprincipal:{a752d6c1-8e61-4faf-9084-97124f7b3596} Line Number 1, Column 1:</code></p>
  
  <p>I know it is not much to work with so if ye need anymore information just ask, but can anyone shine some light on this for me?</p>
