Sql developer behavior, expands table.* to show all fields?

Question

Am I doing something wrong, or does sql developer (10g) have an odd behavior?
If I create a view
select mytable.* from mytable
it saves the view like
select mytable.myid, mytable.mycol1, mytable.mycol2 from mytable
IE it replaces the mytable.* with a select clause that includes every column individually. I've never seen any sql editor do anything like this.

I have never seen a sql editor make such massive changes to whatever one entered. It's not SQL Developer doing this, it's Oracle itself.
Here I'm not using any editor, just SQL Plus (repeating Solomon's example):
SQL> create view emp_v as select * from emp;
View created.
SQL> select view_name, text from user_views;
VIEW_NAME                      TEXT
EMP_V                          select "EMPNO","ENAME","JOB","MGR","HIREDATE","SAL","COMM","DEPTNO" from empThis is also documented (indirectly) in the SQL Reference manual under CREATE VIEW:
"If the subquery uses an asterisk (*) to select all columns of a table, and you later add new columns to the table, then the view will not contain those columns until you re-create the view by issuing a CREATE OR REPLACE VIEW statement."
That's because the "select *" is expanded to explicitly name all the columns when the view is created.
