Collection and manual file upload

Question

okay, I have a collection. With this collection there can be at least one row or there could be many. Some of the fields are user updateable. So pretty much I have a tabular form on a collection. I have all my page processes to handle the table and perform DML the table correctly. I now have a requirement to be able to upload a file for each row. Therefore what I did was this....
....,'<input name="f18" type="file"/>' as "Disposal Document"....in my select list for my collection. FYI it is PL/SQL returning SQL.
Then in the page processing when I "save" off the collection using the collection API i saved G_F18(i) in clob001. Then just did an insert statement into my table based on the collection. Cool...nothing too hard.
Now to download an image on another page that calls this javascript, just so the document opens in a new window...
function documentpoup(disposal_id){
window.open('/pls/apex/#OWNER#.download_file?pid='+disposal_id,'Attachment','width=800,height=600,toolbar=yes,location=yes,directories=yes,status=yes,menubar=yes,scrollbars=yes,copyhistory=yes,resizable=yes');
</script>now my procedure converts my clob into a blob to download it...
  l_mime_type                varchar2(255); 
  l_length                number; 
  l_content_file_name           varchar2(2000); 
  l_content_file           blob;
  myclob clob;
l_dest_offset   integer := 1;
l_source_offset integer := 1;
l_lang_context  integer := DBMS_LOB.DEFAULT_LANG_CTX;
l_warning       integer := DBMS_LOB.WARN_INCONVERTIBLE_CHAR;
begin
  select null, disposal_document, item_number||'-'|| org_code ,dbms_lob.getlength(disposal_document)
    into l_mime_type, myclob, l_content_file_name, l_length 
    from material_disposal
    where disposal_id = pid;
  DBMS_LOB.CREATETEMPORARY(l_content_file, TRUE);
  DBMS_LOB.CONVERTTOBLOB
   dest_lob    =>l_content_file,
   src_clob    =>myclob,
   amount      =>DBMS_LOB.LOBMAXSIZE,
   dest_offset =>l_dest_offset,
   src_offset  =>l_source_offset,
   blob_csid   =>DBMS_LOB.DEFAULT_CSID,
   lang_context=>l_lang_context,
   warning     =>l_warning
  owa_util.mime_header(nvl(l_mime_type,'application/msword'), FALSE ); 
  htp.p('Content-length: ' || l_length); 
  htp.p('Content-Disposition: inline; filename="' || l_content_file_name || '"');
  owa_util.http_header_close; 
  wpg_docload.download_file(l_content_file);  When the file downloads all I have in my "docuemnt" is the name of the file...It is like the file is not actually being uploaded. So something is wrong.... :(
Some more info. The reason I am doing a CLOB and not just BLOB is becasue of the collection. If I could figure out a way not to mess with the CLOB and only use the BLOB that would be cool, but since I am not using an apex item and I am using just html...for some reason the files will not go into the wwv_flow_files table. I have done a dummy page to test this and I can't get it to work...i.e. if I have an apex item that is a file browse type then the file is uploaded, but if I have an html region with an input type of file then that file is not uploaded....has anyone seen or had to do anything like this???or could anyone point me in the right direction?!?
Thanks,
David
