Leonardo Uribe updated TOMAHAWK-1297:
-------------------------------------
Status: Patch Available (was: Open)
> Redirect to a JSF page when Throwable exception or error occur
> --------------------------------------------------------------
>
> Key: TOMAHAWK-1297
> URL: https://issues.apache.org/jira/browse/TOMAHAWK-1297
> Project: MyFaces Tomahawk
> Issue Type: New Feature
> Reporter: Leonardo Uribe
> Assignee: Leonardo Uribe
> Attachments: nullPage.jsp, patchErrorRedirect.patch
>
>
> This issue was originally open as MYFACES-1889 but this enhancements should
> be here.
> One possible enhancement to the error handling feature of myfaces could be
> the capability of redirect to a jsf page.
> I have studied the issue in deep and the thing could be as described below:
> 1. Add this configuration to WEB-INF/web.xml
> <context-param>
> <description>
> Handle exceptions with jsf redirect page.
> </description>
>
> <param-name>org.apache.myfaces.ERROR_HANDLING_REDIRECT_PAGE</param-name>
> <param-value>true</param-value>
> </context-param>
> 2. Define a navigation rule like this:
> <navigation-rule>
> <from-view-id>*</from-view-id>
> <navigation-case>
> <from-outcome>java.lang.NullPointerException</from-outcome>
> <to-view-id>/nullErrorPage.jsp</to-view-id>
> </navigation-case>
> </navigation-rule>
> Note that in from-outcome there is defined the class name of the error to be
> redirected by this page.
> The first test of this feature has been successful, but there are some
> questions to be solved:
> 1. How to add error information (maybe add as a value on the request scope
> like exceptionList)
> 2. How to handle multiple errors, maybe the best is use a special outcome
> like org.apache.myfaces.MultipleThrowable
> I'll do some test this weekend and add a possible patch of this feature.
