hi,
thanks for your reply but this didn't seem like solve my problem entirely as
PreparableInterceptor gets called before ParameterInterceptor. The upshot
is that i didn't have an access to my parameters which drive prepare method.
Nevertheless i found that probably the easiest solution here is to
use paramsPrepareParamsStack interceptor. Surely i call some of the
interceptor twice but at least i've an access to the parameters.
