Hi; i have found where this link is changed; it's in the java class PageLabelLinkService.java.. i have modified it (i attach my new version... but i'm not sure that it works very well i must test it); the problem, now is that i can't take the request parameter called sid in the request..... this thing will make me become crazy.... Can anybody help me? Thanks.
