[rules-users] how to check HashSet size in drool

[rjr201]

I think this would work:

rule "geo_map2" 

        when 
                Creative($id : id, geo_type == 1, geo_mapList.size() == 0)            
        then 
                System.out.println("geo_map2 fail for  CreativeId--"+$id ); 
end
