[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-3599) Seam-gen : Icefaces war project throws IllegalStateException

[Dan Allen (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBSEAM-3599?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12434723#action_12434723 ] 

Dan Allen commented on JBSEAM-3599:
-----------------------------------

I can explain why this happens. Hibernate Tools is incorrectly generating a duplicate foreign key, which then results in a duplicate association (vehicles and vehicles_1), which then causes seam-gen to create a duplicate tab in the UI. Since the component ID of the tab is keyed off of the entity name, it is not unique in the page.

viewAdd${childName}ButtonId

The reason Hibernate Tools is creating a foreign key is because hibernate.hbm2ddl.auto is set to update (instead of validate). This is really a bug in Hibernate Tools. There are three workarounds:

1) Change the foreign key definition for ownerUsername so that it matches what Hibernate Tools generates (basically, you have to use the generated key name).
2) Change hibernate.hbm2ddl.auto to none
3) Use an ID that is unique in the event that a two tables with the same child name exist (it is possible in other circumstances anyway).
