Retaining field value for thtmlb:fileUpload

Question

Hi,
I have created a input file field using tag thtmlb:fileUpload. When user selects a file using browse and then navigate to some other views and come back to the view which has file field, then I need to set the value of this field with the file user had previously selected.
Any help on this would be highly appreciated.
Regards,
Vimal

Hi NewLitus,
thank you for your answer.
I know how to check if a file exists. The problem is that I don�t have the opportunity to do this. I have to handle a user input but when the input is somjething like this "kdbfksdbksb", the fileUpload seems to "notice" that this is not a correct file path and the upload action method is not called (I debugged it several times).
here is my code (that�s just a test of course):
public String btUpload_action() {
info("Button Upload pressed");
logger.entering(getClass().getName(), "***btUpload_action()");
UploadedFile uploadedFile = (UploadedFile)getFileUpload1().getUploadedFile();
if(uploadedFile != null) { // or check here if the file exists....
String uploadedFileName = uploadedFile.getOriginalName();
// Some browsers return complete path name, some don't
// Make sure we only have the file name
// First, try forward slash
int index = uploadedFileName.lastIndexOf('/');
String justFileName;
if ( index >= 0) {
justFileName = uploadedFileName.substring( index + 1 );
} else {
// Try backslash
index = uploadedFileName.lastIndexOf('\\');
if (index >= 0) {
justFileName = uploadedFileName.substring( index + 1 );
} else {
// No forward or back slashes
justFileName = uploadedFileName;
Long uploadedFileSize = new Long(uploadedFile.getSize());
String uploadedFileType = uploadedFile.getContentType();
//.....and so on
return null;
the problem is that I cannot do any check because of this strange behavior!
