I had a property that used to be not-null="true". Values aren't necessary for that field anymore so I changed it to not-null="false" but the table does not get updated in the database. Adding new properties doesn't give any problems.
Is it possible for hbm2ddl.auto=update to change the the table automatically to remove the not-null="true"? (I know I can just write a sql script to change it but would like to let it get updated automagically)
