Similar to the existing Security methods Identity.hasRole() and Identity.hasPermission() I want to add a Identity.hasRight() functionality that takes database based rights for authorisation of methods and pages.

@Name("org.jboss.seam.security.identity")
@Scope(ScopeType.SESSION)
@Install(precedence = Install.APPLICATION)
@BypassInterceptors
@Startup
public class RightBasedIdentity extends RuleBasedIdentity 
{
  private Map<String, AuthorisationRight> authorisationRights = new HashMap<String, AuthorisationRight>();

  public boolean addRight(AuthorisationRight right)
  {
     :
  }

  public boolean hasRight(String rightName)
  {
     :
  }

This works quite well. The problem is how to extend the @Restrict annotation and user interface usage. The new security method should be used as follow, if possible:

Code:
@Restrict("#{s:hasRight('address:change')}")

User Interface:
<h:outputLink ... rendered="#{s:hasRight('address:change')}"

I found out that these security methods are defined in class SeamFunctionMapper. Is it possible to adapt this class anyhow and tell seam to to use it?

Thanks for your help.
