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

[Blake Martin (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-772?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=42467#action_42467 ] 

Blake Martin commented on HHH-772:
----------------------------------

This is an issue for me, as well. In my case, the value is a POJO with several fields. They're normally not null, but can be cleared by application users. If they're all null, this issue occurs.

As a workaround, I put a dummy property on my POJO. I'm a bit irritated that I have to waste DB space with a dummy column and pollute my POJOs to get around this buggy behavior.

> Inserting "something", null manually into the underlying table and
