Eliseu -
Unfortunately with the forum software not escaping any XML content, I'm having a real hard time figuring out what kind of problem you are having with detail disclosure. I did post a response to your message in the UIX forum:
Problems with details disclosure
You might want to check out my response and post any follow-ups there...
