Hi all, I am using Mapnik in order to render OSM from Postgre/PostGIS DB.

My code is like this

mapnik::feature_type_style road_blocked_style; rule road_blocked_rule;

road_blocked_rule.set_filter(parse_expression("[osm_id] = '61924590'"));

stroke road_blocked_rule_stk(color(255,0,0), 3.0); road_blocked_rule.append(line_symbolizer(road_blocked_rule_stk)); road_blocked_style.add_rule(road_blocked_rule); map.insert_style("road_blocked_style", road_blocked_style);

ISSUE: With the filter parse_expression("[osm_id] = '61924590'"), there is no result! ( like no street with this ID would be found in the DB). But I am sure that the ID is valid.

I have read that there has been issues with the convertion to BIG INT type. I am using mapnik-v2.2.0.

How could I solve this issue? Do you have any ideas?

Thank you in advance!
