Lukasz Lenart commented on WW-4042:
-----------------------------------
This is related to restrictions in ParameteresInterceptor which throws aways
names of params that don't match acceptedParamNames pattern. You can use
ParameterNameAware interface to relax restrictions per action or change
acceptedParamNames pattern (which can be dangerous).
