I'm using SQL Developer v1.2.1 build main32.13 against an Oracle 10.2
database. I can create and edit new triggers. Triggers that were made
a few years ago are editable but the only code which is visible are
the words 'create or replace'. However, when I access these older
triggers with PL/SQL Developer all the code is visible! I checked the
owner, table owner etc. in dba_objects and dba_triggers but the
settings are the same for the newer and the older triggers. Anyone any
idea what's going on?

Thanks,

Peter
