I have a problem with @PostFilter... it's never called.
I have tried to configure both AffirmativeBased and UnanimousBased voting system without any luck.
The only voter thats called is this one:
org.springframework.security.access.vote.Affirmati veBased - Voter: org.springframework.security.access.vote.RoleVoter @7d3e4a, returned: 1

Here is the relevant configs:
Interface:
Code:
public interface SectionService {
	@PostFilter("hasPermission(filterObject, 'VOTE_CATEGORY_READ')")
	public List<Section> getSectionsForCompany(Long id);
}
security.xml:
HTML Code:
<global-method-security 
		secured-annotations="enabled" 
		pre-post-annotations="enabled">
		<expression-handler ref="expressionHandler"/>
	</global-method-security>
