| /** |
| * Tests the Session read refactoring / reading through the write connection |
| * properly feature. |
| * <p> |
| * Now that we can trigger valueholders directly by executing a query on the |
| * UnitOfWork, an obvious question is what happens when the query is automatically |
| * a conformming query? |
| * <p> |
| * It seems ideal that when you delete an address and then go employee.getAddress() |
| * you get back null. I.e. conforming is done on the indirection. However |
| * it is not good in that the clone==backup, so merge will not update the |
| * shared cache version. |
| * <p> |
| * Or maybe it is safe, but do we want to do a full conforming when triggering |
| * a valueholder? That could slow things down significantly. And also we |
| * will only do this when in transaction, which is not consistent at all. |
