[richfaces-issues] [JBoss JIRA] (RF-12028) a4j:outputPanel - Error message enhancement

a4j:outputPanel - Error message enhancement ------------------------------------------- Key: RF-12028 URL: https://issues.jboss.org/browse/RF-12028 Project: RichFaces Issue Type: Feature Request Security Level: Public(Everyone can see) Environment: JSF / Mojarra 2.1.6 - cssparser-0.9.6 - guava-11.0.1 - hibernate-validator-4.2.0.Final - springframework 3.0.6.RELEASE - richfaces--4.2.0.Final - sac-1.3 - FireFox 10 - WAS 8.0.0.1 / Windows 7 Reporter: Jean ANDRE Labels: waiting_on_user When we set an non existing attribute on a4j:outputPanel, for eg. "class" because we have converted a div to a a4j:outputPanel, the error message displayed at the user interface does not inform the developer about the faulty component. The message we got is only : > Error 500: javax.servlet.ServletException: Setter not found for property class This error message is not very helpful to debug.... ;) {code} <a4j:outputPanel id="product" layout="block" class="dark-box" rendered="#{productBean.expanded eq true}"> {code} We should have, as usual, the line of the XHTML file or the component name, the line number, well something more accurate that really help to go faster.
