[jbossseam-issues] [JBoss JIRA] Resolved: (JBSEAM-2947) seam-gen crud app throws exception if duplicate entry added

https://jira.jboss.org/jira/browse/JBSEAM-2947?page=com.atlassian.jira.pl...
]
Dan Allen resolved JBSEAM-2947.
-------------------------------
Fix Version/s: 2.0.3.CR2
Resolution: Done
I came up with a nice short-term solution, which is to catch the exception in pages.xml
and direct the user to the error page with a message about entering a duplicate record.
<exception class="javax.persistence.EntityExistsException">
<redirect view-id="/error.xhtml">
<message severity="warn">Duplicate record</message>
</redirect>
</exception>
Long-term, we will want to bake a check for a duplicate record into the Home component. I
have added this to my plan.
seam-gen crud app throws exception if duplicate entry added

Key: JBSEAM-2947
URL: https://jira.jboss.org/jira/browse/JBSEAM-2947
Project: Seam
Issue Type: Bug
Components: Tools
Affects Versions: 2.0.2.CR2
Reporter: Jay Balunas
Assignee: Dan Allen
Fix For: 2.0.3.CR2, 2.1.0.CR1
Create a seam-gen project and reverse engineer a DB (I used the tables from the
release-process.txt).
Add an new entry in one of the tables then attempt to add another identical entry ( just
the primary key will do it as well). You will see an exception (jsf error page) that
basically says cannot add duplicate entry.
Could just add a simple check instead of throwing the exception.
