Opera-Fileupload-Items are not recognized if empty

           Summary: Opera-Fileupload-Items are not recognized if empty
           Product: Commons
           Version: 1.0 Final
          Platform: PC
        OS/Version: Other
            Status: NEW
          Severity: Critical
          Priority: Other
         Component: File Upload
        AssignedTo: commons-dev@jakarta.apache.org
        ReportedBy: wknauf@hg-online.de
                CC: wknauf@hg-online.de


Defining a fileupload-control on a webpage:
<input type="file" name="File1">

Then I parse the request by FileUpload:
org.apache.commons.fileupload.DiskFileUpload fileUpload = new 
org.apache.commons.fileupload.DiskFileUpload();
...some initialization

//Process request:
java.util.List list = fileUpload.parseRequest( request );

//Loop through the fields:
for (int i = 0; i < list.size(); i++)
{
  org.apache.commons.fileupload.FileItem fileItem = 
(org.apache.commons.fileupload.FileItem) list.get(i);

  //Check type:
  if (fileItem.isFormField() == true)
  {
     //Form-Field:
     System.out.println ( "IsFormField: " + fileItem.isFormField() + ", 
FieldName: " + fileItem.getFieldName() + ": " + fileItem.getString("ISO-8859-
1")  );
   }
   else
   {
     //File !
     System.out.println ( "IsFormField: " + fileItem.isFormField() + ", 
FieldName: " + fileItem.getFieldName() + ", File: " + fileItem.getName() + ": " 
+ fileItem.getContentType() );
   }
  }
 
The output looks like this with Opera (5 File-Upload-Items, Item 1 has a valid 
file):
IsFormField: false, FieldName: File1, File: thecorrectfilename.txt: text/plain
IsFormField: true, FieldName: File2: 
IsFormField: true, FieldName: File3: 
IsFormField: true, FieldName: File4: 
IsFormField: true, FieldName: File5: 

What you see is that empty FileUpload-Fields are recognized as formfields.
(hope that I didn't break important info while modifiying the code and output 
to a more readable form).

My Opera version is 7.21.
