APEX

I was adding some functionality to an APEX application and (as I periodically do) took a quick look for invalid objects. I was shocked at the list that popped up.

SQL> select OWNER, OBJECT_TYPE, OBJECT_NAME from dba_objects
  2   where STATUS = 'INVALID';

23 rows selected.

I'm not worried about the APPS or PEOPLENETIF ones - one is in the recycle bin and the other is under development. The others all look like they apply to APEX. I tried running a quick script to individually recompile invalid objects and kept getting the following error:

SQL> ALTER SYNONYM PUBLIC.WWV_FLOW_WEB_SERVICES COMPILE;
ALTER SYNONYM PUBLIC.WWV_FLOW_WEB_SERVICES COMPILE
              *
ERROR at line 1:
ORA-00995: missing or invalid synonym identifier

I also tried doing

EXEC UTL_RECOMP.recomp_serial('PUBLIC');

Nothing seems to work. I can still log in/run my applications, but I'm concerned about these objects. I'm currently running 3.2 (been through all upgrades from 2.0) and haven't made any changes to db schema out of ordinary (adding tables, adding columns to tables) and those were just my data schemas. I never touch the APEX schemas.

Any ideas what is going on and how to fix these objects?
