Row.remove() problem

Question

I have problem that sometimes remove() method doesn't work (I tried viewobject.removeCurrentRow() with the same result).
When I pass following steps:
1) 2 rows are removed:
vo.executeQuery();
while ((row = vo.first()) != null) row.remove();
2) 1 row is inserted:
row = vo.createRow();
row.setAttribute(attr, value);
vo.insertRow(row);
3) write out contents of vo (it is right - 1 inserted):
vo.executeQuery();
vo.reset();
while ((row = vo.next()) != null) System.out.println(row.getSomething());
4) commit()
5) write out contents of vo (it is sometimes right - 1 inserted row, simetimes bad - 2 rows (1 inserted and 1 removed)):
vo.executeQuery();
vo.reset();
while ((row = vo.next()) != null) System.out.println(row.getSomething());
(6) if I get values directly from database (sqlplus) - I can see the same rows I see from point 5).)
So the problem occures sometimes inside commit() - sometimes removed row are not removed inside database!
My VO is second detail - master1->master2->myvo.
My SQL dialect is SQL92 and type mapping Oracle. I use JDeveloper 9.0.5.2
Thank you very much for any help...

Answer 1

I found that if I change SQL dialect to Oracle, then everything os OK.
It seems there is a bug while SLQ92 dialect is set...
Anybody has similar experiencies?
