[jira] Commented: (OPENJPA-834) State field mapped to XML column has incorrect value when loaded from database

["Milosz Tylenda (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OPENJPA-834?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12664215#action_12664215 ] 

Milosz Tylenda commented on OPENJPA-834:
----------------------------------------

The XJC generator can be forced to generate setters for collections by using a plug-in [1]. The manual could be updated with that information.

> The org.apache.openjpa.persistence.xmlmapping.xmlbindings.myaddress.Address is a class with JAXB annotations. It has a property street of type List<String>. When an entity containing Address in its state field is loaded from database, the street property is empty.
> My initial investigation led me to a conclusion that the issue is caused by a proxy returned from ProxyManagerImpl.newCustomProxy(Object) which does not behave correctly.
