Hi Davide; I have only been following along from the sidelines. Sounds
like you are making good progress.

I was going to check your community page to see if I could follow the
build directions - but it seems the wiki is down. I will email
admin at refractions.net. :-)

There is an open bug report, Mauricio was looking at it. I will try
and check in with him, and perhaps Jesse to see what is going on.

The filter data structure is a fixed vocabulary; usually implementors
such as yourself go through the filter (using a filter visitor)
splitting it into two:
1. a filter that can be encoded into a test done by your database
2. a filter that cannot be encoded; and must be done "post" processing
(you can use the filter data structure directly as it has a method to
perform a true/false test on a feature, map or java bean).
