Wrong script in create table window under certain circumstances.
Steps to reproduce the problem.
1) Open create table window and enter table name.
2) check "Show advanced features" if it is not already checked.
3) Add a column. Set datatype to whatever.
4) Add another column. Set datatype to CLOB
5) click over to first column, then back to 2nd.
6) change the column name on 2nd column.
7) Click Show SQL. Bug: the SQL has LOB references to both the original and renamed 2nd
