[hibernate-issues] [Hibernate-JIRA] Commented: (ANN-793) @ManyToOne - @OneToMany doesn't work with @Inheritance(strategy= InheritanceType.JOINED)

[Martin Gercsak (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/ANN-793?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=33874#action_33874 ] 

Martin Gercsak commented on ANN-793:
------------------------------------

Same problem here. Once I use @Inheritance(strategy= InheritanceType.JOINED)  on a class mapped to multiple tables I get "table not found" even if there is no derived class yet. If I remove @Inheritance the code works.
