file downloading error with IE7
Hi,
I'm trying to execute the function in my backing bean
ByteArrayOutputStream stream = new ByteArrayOutputStream();
createExcelFile(stream);
HttpServletResponse response = (HttpServletResponse) faces
.getExternalContext().getResponse();
response.setContentType("application/vnd.ms-excel");
response.setContentLength(stream.size());
response.setHeader("Content-disposition",
"inline; filename=\"Timesheet.xsl\"");
try {
ServletOutputStream out;
out = response.getOutputStream();
out.write(stream.toByteArray());
faces.responseComplete();
} catch (IOException e) {
e.printStackTrace();
}
Everything is great when I save the file, but when I open it in IE7 directly I can see all the xls content but I have error message in my Tomcat console window:
javax.servlet.jsp.JspException: Cannot find FacesContext
at javax.faces.webapp.UIComponentTag.doStartTag(UIComponentTag.java:427)
at com.sun.faces.taglib.jsf_core.ViewTag.doStartTag(ViewTag.java:125)

The problem is the following:

After that I can download the file - it's ok.
When xls file is opened in IE7 window I see the expected xls content but
IE7 sends two additional requests and they
cause the error message:
Cannot find FacesContext - which is true because nothing is availabe. Is any way to exclude HTTP OPTIONS form jsf?
