Hi all,
I have been using seam for a while now and really like it. It makes JSF so much more
usable.
My question is, no matter what exception is thrown, I keep getting the same error screen.
My pages.xml file refers to several different redirects for exceptions yet I keep getting
the same "An error occurred: entityManager is null" screen. The stack trace also
displays the same wrapper exception which references a seam generated entity that has no
relevance to the current exception.
Here is my pages.xml file:
<exception class="org.jboss.seam.framework.EntityNotFoundException">
| <redirect view-id="/error.xhtml">
| <message>Not found<</message>>
| </redirect>
| </exception>
|
|
| <exception class="javax.persistence.NoResultException">
| <redirect view-id="/error.xhtml">
| <message>Dealer Not found</message>
| </redirect>
| </exception>
|
| <exception class="javax.persistence.EntityNotFoundException">
| <redirect view-id="/error.xhtml">
| <message>Not found</message>
| </redirect>
| </exception>
|
| <exception class="javax.persistence.OptimisticLockException">
| <redirect view-id="/error.xhtml">
| <message>Another user changed the same data, please try
again</message>
| </redirect>
| </exception>
|
| <exception
class="org.jboss.seam.security.AuthorizationException">
| <redirect>
| <message>You don't have permission to do this</message>
| </redirect>
| </exception>
|
| <exception class="org.jboss.seam.security.NotLoggedInException">
| <redirect view-id="/home.xhtml">
| <message>Please log in first</message>
| </redirect>
| </exception>
|
| <exception class="java.lang.RuntimeException">
| <redirect view-id="/error.xhtml">
| <message>Unexpected error, please try again</message>
| </redirect>
| </exception>
|
| <exception>
| <redirect view-id="/error.xhtml">
| <message>Unexpected error, please try again</message>
| </redirect>
| </exception>
|
Here is the stack trace I get for then throwing a test runtime exception:

The AppliedTransactionList entity in the stack trace is the unrelated (seam generated)
element.
Any help would be greatly appreciated.
Thanks,
