Hi,
Hibernate 3.2 cr2
I have a table (middle_table) which joins two other tables (left_table and right_table). middle_table is not a pure link table - it contains some other attributes, but the combination of left_id and right_id are unique for the middle_table
left_table 1--------* middle_table *------------1 right table
When I remove the middle entries from the left and right tables in the same transaction that I add another entry for the same left and right combination, I get a constraint violation. It appears as if the delete is scheduled for AFTER the insert. Adding the line session.flush() between the 'delete' and the 'insert' solves the problem. BUT - I don't have access to the session in my object model (for obvious reasons) and wonder how one can get around this.
