Connect_By_Root: Difference between Oracle 10.2.0.1.0 and 11.1.0.6.0

Question

Hello,
we use the connect_by_root function. Now we would like transfer our application to 11g 64Bit
Under the following Database 10g it works fine
Oracle Database 10g Release 10.2.0.1.0 - Production
PL/SQL Release 10.2.0.1.0 - Production
CORE     10.2.0.1.0     Production
TNS for 32-bit Windows: Version 10.2.0.1.0 - Production
NLSRTL Version 10.2.0.1.0 - Production
drop table hier;
create table hier
parent varchar2(30),
child varchar2(30)
insert into hier values(null,'Asien');
insert into hier values(null,'Australien');
insert into hier values(null,'Europa');
insert into hier values('Asien','China');
insert into hier values('Asien','Japan');
insert into hier values('Europa','Deutschland');
set linesize 5000;
column child format a80
select
connect_by_root child || ' #Pipapo#' as Child1
,sys_connect_by_path(child,'/') as Path
from
hier
start with parent is null
connect by prior child = parent;
Output:
CHILD1 PATH
Asien #Pipapo# /Asien
Asien #Pipapo# /Asien/China
Asien #Pipapo# /Asien/Japan
Australien #Pipapo# /Australien
Europa #Pipapo# /Europa
Europa #Pipapo# /Europa/Deutschland
Under the following Database 11g we get the following error:
Oracle Database 11g Release 11.1.0.6.0 - 64bit Production
PL/SQL Release 11.1.0.6.0 - Production
CORE     11.1.0.6.0     Production
TNS for 64-bit Windows: Version 11.1.0.6.0 - Production
NLSRTL Version 11.1.0.6.0 - Production
FEHLER in Zeile 1:
ORA-00932: Inkonsistente Datentypen: NUMBER erwartet, - erhalten
The result from conect_by_root cannot concat with ' #Pipapo#'
We need this funktionality. What can we do. Its a bug in 11g ?
best regards
