Actionscript runtime error 3769

Hello,

I have the same scenario as neelam_Ramesh.

I applied his solution but I cannot get my application working again. Can somebody help me with this please?

Before the new Flash Player everything was working fine in all browser, well at list I tested in FireFox, Chrome, IE 8/9/10/11 in Windows and Safari in Mac.

Now only IE 8 is working witch no very useful since my clients are using most Safari, Chrome and FireFox.

I have my clients and my manager waiting for the solution.

Flex code:

var serverScript:String = tomcatServlet + "setPDF&method=ATTACHMENT&name=routes123456.pdf";

//printPDF.save(Method.REMOTE, serverScript, howToOutput, "routes123456.pdf");

bytesTemp : ByteArray = printPDF.save(Method.LOCAL);

sendRequest:URLRequest = new URLRequest(serverScript);

sendRequest.method = URLRequestMethod.POST;

sendRequest.data = bytesTemp;

navigateToURL(sendRequest,'_blank');

java code:

// ****************************************************

protected void setPDF(HttpServletRequest request,

   HttpServletResponse response) throws ServletException, IOException {

  int i = 0;

  int k = 0;

  int maxLength = request.getContentLength();

  byte[] bytes = new byte[maxLength];

  String method = request.getParameter("method");

  String name = request.getParameter("name");

  ServletInputStream si = request.getInputStream();

  while (true) {

   k = si.read(bytes, i, maxLength);

   i += k;

   if (k <= 0) {

    break;

   }

  }

  if (bytes != null) {

   ServletOutputStream stream = response.getOutputStream();

   response.setContentType("application/pdf");

   response.setContentLength(bytes.length);

  //response.setHeader("Content-Disposition", method + ";filename="+ name);

   response.setHeader("Content-Disposition","inline; filename="+ name);

   stream.write(bytes);

   stream.flush();

   stream.close();

  }

}

Thanks !!!

Unfortunately, this was an intentional and necessary change required to address a security issue reported by an external researcher.  We sincerely apologize for the inconvenience. 

After careful consideration, we found that the only way to truly resolve the issue was to disable support for custom headers in NavigateToURL.

While we would prefer to provide advanced notification for security changes that affect existing content, experience has taught us that it is not a viable approach, and ultimately puts customers at more risk.  We go to great lengths to preserve backward-compatibility in general, but it's our responsibility to balance those considerations with the overall security of end-users and the web at large.

Custom headers continue to be supported via the URLRequest class, and we encourage developers to use those APIs where custom headers are required.

This sounds like it is a Flash Player issue and not an Actionscript issue.  You might find help in the Flash Player forum(s) rather than here.

I can include it, but it probably won't help much:

The line of code throwing the error (it's an AlivePDF object):

pdf.save( Method.REMOTE, "http://lamp.countygp.ab.ca/webmap/AlivePdfGen.php", Download.INLINE, "mapexport.pdf","_blank" );

If we use veiwer version is 13.0.0.206 it's fine but 13.0.0.214 thows this error.
