Webflows with different interceptors

Hello,

usually in a dispatcher-servlet there is a single org.springframework.webflow.mvc.servlet.FlowHandle rMapping and a single flowRegistry - which can have multiple flow-locations.
Unfortunately, interceptors are declared in the FlowHandlerMapping, meaning all flows use the same interceptors.

My problem is, some of my webflows need additional interceptors.

How can I achieve this?
I already tried to create a second FlowHandlerMapping inside the servlet, but could not get it to work.

any ideas are welcome,
Joey
