WUT-113 Too many rows when using Webutil to upload a doc or pdf

Question

Hi All,
I am using Webutil to upload and view files and am receiving the error msg 'WUT-113 Too many rows matched the supplied where clause'
The process works fine for uploading photos but not when I try and upload documents and pdf files.
I am on v 10.1.2.0.2 and using XP.
The code example (for documents) is outlined below but think that the issue must be to do with some sort of incorrect Webutil configuration
on my machine.
declare
     vfilename varchar2(3000);
     vboolean boolean;
begin
     vfilename := client_get_file_name('c:\',file_filter => 'Document files (*.doc)|*.doc|');
     vboolean := webutil_file_transfer.Client_To_DB_With_Progress
( vfilename,
'lobs_table',
'word_blob',
'blob_id = '||:blob_id,
'Progress',
'Uploading File '||vfilename,
true,
'CHECK_LOB_PROGRESS');
end;
Any assistance in this matter would be appreciated.
kind regards,
Tom

Hi Sarah,
Many thanks for the reply.
All I'm trying to do is to click on the Browse Document button in a form to upload
a document (in this example) from my machine and save it to the db table called lobs_table
using the webutil_file_transfer.Client_To_DB_With_Progress program.
When I first access the form the field :blob_id is populated (by a When-create-Record trigger)
with a value made up of sysdate in NUMBER format as DDMMHHMISS e.g. 0106101025
When I press 'Browse Document' - a button in the form) and the dialog box is opened and
I select a document and click ok then I see the error message 'WUT-113 Too many rows matched the supplied where clause' and yet the where clause element of the call to webutil_file_transfer.Client_To_DB_With_Progress program
should be the :blob_id value ('blob_id = '||:blob_id) i.e. should be a single value populated in the field when I first access the form - so why am I seeing the when too many rows error?
I may be missing something obvious as I've only just started using Webutil.
Kind regards,
Tom
