How to handle missing servlet request in consent action ?

[Tom Zeller]

How should the ExtractConsent action handle a missing HTTP servlet request ?

The servlet request is necessary to extract user input. Currently, the
ExtractConsent action just logs to debug. The lack of a servlet
request is either some weird error or due to misconfiguration in the
flow bean definition file.

It seems the action could either (a) log to error instead of debug or
(b) return an error Event, but I've been avoiding creating new events
for consent.

Thoughts ?

Thanks.
