af:commandLink does not prompt download File Dialog Not available

Question

I am using following code for downloading pdf file
<*af:commandLink* text="#{row.docContentID}" id="cl31"
immediate="true" partialSubmit="true">
<af:fileDownloadActionListener contentType="application/pdf"
method="#{pageFlowScope.BulletinsBean.getDocument}"
filename="#{row.docContentID}.pdf"/>
</af:commandLink>
where i written code in getDocument() method of bean
where i have written file in outputstream which comes from input stream as follows:
InputStream stream = null;
int reportedSize = Integer.parseInt (response.getHeader ("Content-Length"));
//String contentsInHex = "";
//-------------------Write to browser---------------------
// Prepare.
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext externalContext = facesContext.getExternalContext();
HttpServletResponse responseHttp = (HttpServletResponse) externalContext.getResponse();
// Initialize response.
responseHttp.reset();
responseHttp.setContentType("application/x-pdf");
responseHttp.addHeader("Content-Disposition", "attachment ; filename="+contentId +".pdf");
responseHttp.setContentLength( reportedSize);
OutputStream output = responseHttp.getOutputStream();
try
stream = response.getResponseStream ();
buf= new byte[100];
int numRead;
while ( (numRead = stream.read(buf) ) >= 0) {
output.write(buf, 0, numRead);
facesContext.responseComplete();
output.close();
If i am using simple *<h:commandLink>* then it works fine but i am not able to get the text of that link to my action method . In this case i get all the table links text .
There are many links on the table.
But at the time of using af:commandlink i am not able to get the download dialog promp in firefox it gets directly downloaded and in case of IE8 it gives me bar upperside for getting download (This is blocked for security resons and when i click there is option for download)

ok Thank you but what about <h:commandLink>
When i Select on of the <h:commandlink> it gives me list of all commandlinks values in the table
Will you please guide me.I used following code for getting link i get selected
public String getPdfDocument()throws IOException {
String Value = null;
FacesContext facesContext = FacesContext.getCurrentInstance();
Application app = facesContext.getApplication();
ExpressionFactory elFactory = app.getExpressionFactory();
ELContext elContext = facesContext.getELContext();
ValueExpression valueExp = elFactory.createValueExpression(elContext, "#{row.docContentID}", Object.class);
//System.out.println("Selected Value---"+valueExp.getValue(elContext));
if(valueExp.getValue(elContext) !=null) {
Value = valueExp.getValue(elContext).toString();
DCBindingContainer bindings =
(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding iter =
(DCIteratorBinding)bindings.findIteratorBinding("ListOfDocumentsIterator");
Row row=iter.getCurrentRow();
Value= row.getAttribute("docContentID").toString();//JSFUtils.resolveExpression("#{row.docContentID}").toString();
System.out.println("Selected Value is---"+Value);
return null;
}
