Subject [jira] Commented: (OPENJPA-1933) @ElementCollection loose proxytype after serialisation
Date Wed, 23 Feb 2011 03:35:38 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-1933?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12998141#comment-12998141

Michael Dick commented on OPENJPA-1933:
---------------------------------------

To answer your question, IgnoreDetachedStateFieldForProxySerialization is only when we replace
a proxy field ( so collections, or temporal fields). It doesn't bleed into other parts of
the code. 

But you shouldn't have to use it - if you have a DetachedStateManager (that should be some
consolation).

> usually an @ElementCollection field loaded from the database will be created as a org.apache.openjpa.java$.util$.ArrayListProxy.
> After serialisation/deserialisation (with DetachedStateField=true) the List will be recreated
as standard java.util.ArrayList.
> This has the bad side effect, that any subsequent add to this ElementCollection will
not set the _dirty field in the DetachedStateManager and any changes in the ElementCollection
will not get saved to the database.
