This link ( http://www.joaofrassetto.pe.hu/ci_santan...rio/entrar ) prints "Inicio usuarioLogado()." before the user validation and "Final usuarioLogado()." after this validation. The problem occur no more.

This link ( http://www.joaofrassetto.pe.hu/ci_super/...rio/entrar ) prints nothing before or after the user validation. The problem still occur.

The validation is the same for both. If the print is removed, than the code return to sometimes give the error. If the print is put on the validation the error stops.
