Confused ... ALL_DEPENDECIES view does not contain indexes?

Question

I try to generate a installation sequence for all my objects, for this I experimented with the all_dependecies view
1st generate a table with all objects:
<pre>
drop table rank_sources;
create table rank_sources as
select rownum as rn, object_name, object_type, owner from all_objects
where owner = 'SYS';
commit;
select * from rank_sources;
</pre>
afterwards fire a pl/sql
<pre>
set serveroutput on
declare
cursor l_cursor is select * from rank_sources for update;
l_found boolean := false;
begin
for src in l_cursor loop
l_found := false;
for dep in (
select level, referenced_name, referenced_type
from DBA_DEPENDENCIES
where owner = src.owner
and referenced_owner = src.owner
start with name = src.object_name and type = src.object_type
connect by name = prior referenced_name and type = prior referenced_type
loop
l_found := true;
update rank_sources
set rn = src.rn - dep.level
where object_name = dep.referenced_name
and object_type = dep.referenced_type;
end loop;
if not l_found then
update rank_sources
set rn = -9999999999 where CURRENT OF l_cursor;
end if;
end loop;
commit;
end;
</pre>
As you can see, there are potentially indexes with a lower rank than their table. When you do a
<pre>select * from all_dependencies where type like '%INDEX%'</pre>
the result is NULL - I am really confused why indexes are not referencing to their tables?? So in case of Index I have to query seperatly all_indexes.
But when you look at the all_dependecies view definition you can see, index as an expected type - is this a bug? I use Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
<pre>
SET DEFINE OFF;
DROP VIEW SYS.ALL_DEPENDENCIES
/* Formatted on 20.10.2010 12:31:15 (QP5 v5.149.1003.31008) */
CREATE OR REPLACE FORCE VIEW SYS.ALL_DEPENDENCIES
OWNER,
NAME,
TYPE,
REFERENCED_OWNER,
REFERENCED_NAME,
REFERENCED_TYPE,
REFERENCED_LINK_NAME,
DEPENDENCY_TYPE
AS
SELECT u.name,
o.name,
DECODE (o.type#,
0, 'NEXT OBJECT',
1, 'INDEX',
2, 'TABLE',
3, 'CLUSTER',
4, 'VIEW',
</pre>

Ok, so what I have done so far - to get a solution for my requirement - I created a sys view like this:
<pre>
create or replace
view REALLY_ALL_DEPENDENCIES as
select *
from ALL_DEPENDENCIES
union
select owner, index_name, 'INDEX', table_owner, table_name, table_type, null, null
from all_indexes
union
select p.owner, p.table_name, 'TABLE', f.owner, f.table_name, 'TABLE', null, null
from all_constraints p
join all_constraints f
on F.R_CONSTRAINT_NAME = P.CONSTRAINT_NAME
and F.CONSTRAINT_TYPE = 'R'
and p.constraint_type='P'
</pre>
Since union is checking for duplicates, it should be harmless to use this view from now on :-) ... ok, performance is not really good, but I do not use the view every minute - maybe once a day.
Thanks and cheers
