Oracle ADF: ORA-01460 4000 chars problem

Question

Hello,
please excuse my bad english. I hope you will understand what I mean.
I hope I'am right here with my Problem:
I hava a web application written with Oracle ADF in jDeveloper. A View-Object contains the SQL-Statemant to search with a bind variable (Type: String) and uses Oracle Text.
WHERE contains(Index, :mySearchString, 1) > 0
Java generates the String (Type: String) that might have a length of 12 chars, 1234 chars or maybe something about 4000 chars.
If the String is below 4000 chars, there is no problem.
But if he exceeds the 4000 chars I get a exception with the message "ORA-01460:     unimplemented or unreasonable conversion requested".
How to execute this statement with a String longer than 4000 chars?
Could someone help me?
I am at my wit's end.
Thank you!
DB: Oracle 10g Enterprise Edition (10.1.0.4.2)

Thank you! Good to know that it isn't impossible to enhance this.
I wrote a sql function:
create or replace function mysearch(p_arg varchar2)return sys_refcursor is
l_resultset sys_refcursor;
begin
open l_resultset for select ... from ... where contains(attribut, p_arg);
return l_resultset;
end;
and create a View-Object. This View-Object has the follwing SQL-Statement:
SELECT mysearch(:p_arg) AS MY_SEARCH FROM DUAL
but no attributes! And the Object which I get has only 1 row. It should contains about 9000.
And I get anyway the message "ORA-01460:     unimplemented or unreasonable conversion requested".
In a PL/SQL context varchar2 can be 32KB!? Or not?
Is this a ADF Problem? :-( (I hope so! If not: SORRY)
