> Class hierarchy: Node(Document,Directory)
> I'm asserting an instance of Document into working memory like this:
>     <s:link id="editDoc" styleClass="linkNavigation" action="editDoc" accesskey="E"
>             rendered="#{s:hasPermission('NodeHome', 'edit', currentDocument)}"><u>E</u>dit</s:link>
> This doesn't fire:
> rule RestrictNodeHomeEditAccess
>     no-loop;
>     activation-group "permissions"
> when
>     c: PermissionCheck(name == "NodeHome", action == "edit");
>     Node(nodeWriteAccessLevel : writeAccessLevel, nodeCreator : createdBy)
>     Role(userAccessLevel : name -> (Integer.valueOf(userAccessLevel).intValue() >= nodeWriteAccessLevel.intValue()) )
>     or
>     User(authenticatedUserId : id -> (nodeCreator.getId().equals(authenticatedUserId)) )
> then
>     c.grant();
>     modify(c);
> end;
> This does:
> rule RestrictNodeHomeEditAccess
>     no-loop;
>     activation-group "permissions"
> when
>     c: PermissionCheck(name == "NodeHome", action == "edit");
>     Document(nodeWriteAccessLevel : writeAccessLevel, nodeCreator : createdBy)
>     Role(userAccessLevel : name -> (Integer.valueOf(userAccessLevel).intValue() >= nodeWriteAccessLevel.intValue()) )
>     or
>     User(authenticatedUserId : id -> (nodeCreator.getId().equals(authenticatedUserId)) )
> then
>     c.grant();
>     modify(c);
> end;
> I couldn't find anything in the Drools docs about polymorphism but it looks like Facts are not checked polymorphically. Sad language that is.
