Description
The following bean supports the syntax:
rendered="#{role.ADMIN || role.USER}"
import java.util.Map;
import java.util.AbstractMap;
import java.util.Set;
public class RoleMap extends AbstractMap {
public Object get(Object key) {
FacesContext facesContext = FacesContext.getCurrentInstance();
if (facesContext.getExternalContext()
.isUserInRole((String) key) ) {
return Boolean.TRUE;
}
return Boolean.FALSE;
}
public Set entrySet() {
return null;
}
}

In my own testing, using an AbstractMap caused an exception on bean initialization (I forget what exact exception). Extending from a concrete HashMap solved the issue.
import java.util.Map;
import java.util.HashMap;
import java.util.Set;
import javax.faces.context.FacesContext;
public class UserRoles extends HashMap {
public Object get(Object key) {
FacesContext facesContext = FacesContext.getCurrentInstance();
if (facesContext.getExternalContext()
.isUserInRole((String) key) )
return Boolean.FALSE;
}
}

Philip revised this to extend a different base collection class; Philip, could you paste your code in, state why you revised it, and then close?
