Spring Webflow - access exception using transition.on-exception attribute

Question

I wondering how can I access exception object using on-exception attribute? My current configuration looks like this:

<transition on-exception="{business_exception}" to="errorView" >
</transition>

I have to access some exception attribute in errorView. Does anybody know how can I do it?

This is a rather undocumented part of Spring Web Flow, but according to this thread on SpringSource forum, you can access the exception directly on your view as attributes stateException and rootCauseException.
