How to assign the output of a function to a text area: a PLSQL challenge

Question

I have a function that returns a PLSQL table of varchar4(4000)
Here is its signature in a package:
create or replace package researcher_request_pk
is
TYPE query_table_type is table of varchar2(4000) index by binary_integer;
FUNCTION RequestSQL(P_RRQ_ID in number) return query_table_type;
end;
I use this to get around the 32k limit on clobs and varchar2 variables
I want to assign the output of the function to a text area. I've tried the following PLSQL in a dynamic action and also as the source attribute of the Text Area but it doesn't populate the text area.
Here is the code i'm using
declare
v_table researcher_request_pk.query_table_type;
begin
v_table:=researcher_request_pk.RequestSQL(:P64_RRQ_ID);
for i in 1..v_table.count loop
htp.prn(v_table(i));
end loop;
end;
Any ideas on the correct syntax to do this?
thanks in advance

Thanks for your reply
The function does populate the PLSQL table with data. e.g. If I place that exact code in a PLSQL region it generates the output on the screen with no problems. The problem is just generating the output into the text area.
I want the text area to display the output of the PLSQL table (-a dynamic select SQL statement) which I then plan to execute to return records.( i.e. I've build my own runtime query builder)
My plan is to allow the user to edit the SQL output first before sending the statement for execution.
Funnily enough I do get the very first word of the first cell appearing, namely 'SELECT' but nothing else. Maybe the "||" that follows has something to do with the rest of it not appearing?? hmmm... will experiment more.
