[Pete Muir (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBSEAM-1183?page=all ]

Pete Muir updated JBSEAM-1183:
------------------------------

    Component/s: Exception Handling
                     (was: Core)

> Allow custom ExceptionHandler implementations to be inserted
> ------------------------------------------------------------
>
>                 Key: JBSEAM-1183
>                 URL: http://jira.jboss.com/jira/browse/JBSEAM-1183
>             Project: JBoss Seam
>          Issue Type: Feature Request
>          Components: Exception Handling
>    Affects Versions: 1.1.6.GA
>         Environment: Any
>            Reporter: Mike Quilleash
>
> Currently you can only configure a small subset of actions to occur on an exception (redirect, http-error etc).  Enhancing the exception configuration xml to allow pluggable ExceptionHandler implementations would make this a lot more flexible.
> e.g. pages.xml
> <pages>
>    
>    <!-- the current way, exception class + action -->
>    <exception class="javax.persistence.EntityNotFoundException">
>       <http-error error-code="404"/>
>    </exception>
>    
>    <!-- proposed enhancement -->
>    <exception handlerClass="com.xxx.seam.CustomExceptionHandler"/>   
> </pages>
> These should probably have higher precedence than standard configure-by-exception-class handlers.
