[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-772) null in maps are handled inconsistently
[

]
Nelson Murphy commented on HHH-772:
-----------------------------------
I just encountered this problem as well.
An entry with a null value is entirely different from the absence of an entry (i.e.,
absence of the key). I have seen no rational explanation for PersistentMap's
implementation.
Would someone on the Hibernate team please explain why "A 'sane' schema does
not have 'null values in a map'"? I could understand not supporting a null
key, but what is wrong with a null value?
null in maps are handled inconsistently
---------------------------------------
Key: HHH-772
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-772
Project: Hibernate Core
Issue Type: Improvement
Components: core
Reporter: Max Rydahl Andersen
Fix For: 3.1 beta 1
regarding case 00004729.
group.getUsers().put("something", null);
Does not result in any insert.
Inserting "something", null manually into the underlying table and
when hibernate reads the map will have "something"->null in the map.
