XML Parsing Error: no element found Location: moz-nullprincipal (not strong with ajax)

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 ``` @EventListener(targets="licensingStatus", events="onchange") public void onLicenseStatusChange(IRequestCycle cycle){ cycle.getResponseBuilder().updateComponent("licenceAuthRequiredDiv"); } ``` This is the component that the above code is updating ``` <div jwcid="licenceAuthRequiredDiv@Any"> <span jwcid="@If" condition="ognl:company.licensingStatus == @com.fexco.wuams.valueobject.LicensingStatus@Pass && inApprovalMode()" renderTag="literal:false"> <input jwcid="licensingApprovalDateRequired@DatePicker" disabled="ognl:disabled || isLicensingApprovalDateDisabled()" value="ognl:company.licensingApprovalDate" displayName="message:company.licensingApprovalDate" validators="validators:maxDateToday,required" /> </span> <span jwcid="@Else" renderTag="literal:false"> <input jwcid="licensingApprovalDate@DatePicker" disabled="ognl:disabled || isLicensingApprovalDateDisabled()" value="ognl:company.licensingApprovalDate" displayName="message:company.licensingApprovalDate" validators="validators:maxDateToday" /> </span> </div> ``` 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: `302 Moved Temporarily` and the GET request just hangs with the following: `XML Parsing Error: no element found Location: moz-nullprincipal:{a752d6c1-8e61-4faf-9084-97124f7b3596} Line Number 1, Column 1:` 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?
