I have the same problem, also need to plugin my "customComparator", but as
there is no explanation of the framework, how a RequestHandler is working,
what comes in, what comes out ... just impossible!
Can someone explain where i have to add which code, to just have the same
functionality as the StandardRequestHandler, but also adding a custom
sorting?
Thanks,
Markus
