Exception event listeners. -------------------------- Key: JBSEAM-186 URL: http://jira.jboss.com/jira/browse/JBSEAM-186 Project: JBoss Seam Issue Type: Feature Request Components: Core Reporter: Gavin King Assigned To: Gavin King Fix For: 1.1.0.BETA2 Add an exceptions.xml file in WEB-INF that provides mappings to actions: <exceptions> <exception class="java.lang.IllegalStateException" action="#{exceptions.handleIllegalState}"/> <exception class="java.lang.Throwable" view-id="/error.jsp"/> ... </exceptions> Only the most-specific action for an exception type would be invoked. Not sure how easy it is to implement this right now, since apparently JSF nastily swallows/wraps some exceptions. Need to investigate. (Perhaps what the action around the EJBs, not the JSF lifecycle.)
