[jbossseam-issues] [JBoss JIRA] Resolved: (JBSEAM-1750) Accessing handledException through EL broken
[ http://jira.jboss.com/jira/browse/JBSEAM-1750?page=all ]
Norman Richards resolved JBSEAM-1750.
-------------------------------------
Resolution: Won't Fix
The problem seems to be that the getMessage(int) method on HibernateException confuses the
EL evaluator. I don't know if it is "legal" for a JavaBean to have a method
like that, so it may or may not be a bug on the part of the EL code. Unfortunately, the
offending class (javax.el.BeanELResolver) is outside of Seam and jboss-el, so I'm not
sure this is fixable by us.
Fortunately, in this case, there is a very easy workaround. Instead of using
#{org.jboss.seam.handledException.message}, use
#{org.jboss.seam.handledException.messages[0]}. If you are on Seam 2 using JBoss EL, you
can also use #{org.jboss.seam.handledException.getMessage()}.
Accessing handledException through EL broken
--------------------------------------------
Key: JBSEAM-1750
URL: http://jira.jboss.com/jira/browse/JBSEAM-1750
Project: JBoss Seam
Issue Type: Bug
Components: Core
Affects Versions: 1.2.1.GA
Reporter: Samuel Mendenhall
Assigned To: Norman Richards
Priority: Minor
Fix For: 2.0.0.CR1
Bean:
throw new HibernateException("Test");
pages.xml:
<exception class="org.hibernate.HibernateException">
<end-conversation/>
<redirect view-id="/error.xhtml">
<message
severity="WARN">#{org.jboss.seam.handledException.message}</message>
</redirect>
</exception>
I am correctly redirected to the error.seam page however the message is empty and in my
console I have:
11:52:47,571 WARN [Interpolator] exception interpolating string:
#{org.jboss.seam.handledException.message}
javax.faces.el.PropertyNotFoundException: Bean: org.hibernate.HibernateException,
property: message
....
Furthermore, the documentation says to use #{handledException.message} which is
incorrect, it should be #{org.jboss.seam.handledException.message}.
