Displaying a CLOB value on a report page in an application from a DB-link

Question

Hello, i am having trouble displaying a CLOB value from a DB-Link, i have tried using temporary local tables, but they didnt work.
I am now trying to use a collection (page process) to display the CLOB column's data from the link but to no avail :(
This is my collection source:
declare
  col1   number;
  col2   date;
  col3   clob;
begin
  apex_collection.create_or_truncate_collection('LOBCOLLECTIONPLAN');
  for r in ( select * from TABLENAME@DB-Link ) loop
    APEX_COLLECTION.ADD_MEMBER('LOBCOLLECTIONPLAN',
    p_c001          => r.col1,
    p_c002          => r.col2,
    p_clob001       => r.col3);
end loop;
end;when i run the page it displays 'no data found', yet there is data in the linked DB table.
Is there anything i am doing wrong?
Or is there another way around this?
Thanks in advance

There used to be a problem with pulling CLOB's through dblinks. I don't know if that is still an issue, but I think it probably is, as that is a 'problem' with the database itself.
If you run the same SQL query on your local database, getting the CLOB's from a remote database, do you get any errors or do you get all of the data?
No idea if I'm right or not, but it's something you should be able to test fairly easily.
