Hello,
if i try to see a wrapped package (ex SYS.DBMS_LOB), by right clicking on tree objects, i can't see the full code.

With this select command, we obtain more than one line :
select line, text from dba_source where type = 'PACKAGE BODY' and owner = 'SYS' and name = 'DBMS_LOB' order by line;

We see only the first one, by the tree objetcs.

Thanks
