Master Detail stops working when i try to download a blob filed

Question

Hi All,
I am working on Jdeveloper 11g.
I have a master table with detail , the detail table has a blob field.
when the user tries to download the blob field every thing works fine, but the master detail relation stops working , when the user clicks a row in the master table the detail is not refreshed.
I have to refresh the whole page to start working again .
This is the code I am using for download , along with fileDownLoadActionListener():
public void researchDownloadAction(FacesContext ctx, OutputStream out) {
ExternalContext ectx = ctx.getExternalContext();
Row currentRow = ADFUtils.getIterator("Documents2Iterator").getCurrentRow();
String fileName = (String)currentRow.getAttribute("FileName");
BlobDomain content = (BlobDomain)currentRow.getAttribute("Content");
Long length = content.getLength();
HttpServletResponse response = (HttpServletResponse)ectx.getResponse();
response.setHeader("Content-Disposition", "attachment;filename=\"" + fileName + "\"");
response.setContentLength(length.intValue());
try {
InputStream in = content.getBinaryStream();
byte[] buf = new byte[1024];
int count;
while ((count = in.read(buf)) >= 0) {
out.write(buf, 0, count);
in.close();
out.flush();
out.close();
ctx.responseComplete();
catch (IOException ex) {
System.out.println(ex.getMessage());
ex.printStackTrace();
Thanks.
