Subject: strange StateMachine behaviour

hello I've strange problem with state machine

in my model

state_machine :user_state, :initial => :unconfirmed do
    state :unconfirmed, :value => 0
    state :confirmed, :value => 1
    state :trusted, :value => 2

    event :verify do
      transition :unconfirmed => :confirmed
    end

    event :trust do
      transition [ :unconfirmed, :confirmed] => :trusted
    end
  end
-----------

x    ==> #<Price id: 88, user_id: 1, station_id: 13157,
session_id: "201924b30b53bd38250d396c252b2847", user_type: 2, price:
#<BigDecimal:9f0bdc0,'0.34E2',4(8)>, user_state: 0, created_at:
"2009-12-10 06:22:06", updated_at: "2009-12-10 07:46:33", ip:
"10.10.10.1">
-----------

x.user_state_transitions
    ==> [#<StateMachine::Transition attribute=:user_state
event=:verify from=0 from_name=:unconfirmed to=1 to_name=:confirmed>,
#<StateMachine::Transition attribute=:user_state event=:trust from=0
from_name=:unconfirmed to=2 to_name=:trusted>]
-----------
events.valid_for(x)
    ==> [#<StateMachine::Event name=:verify transitions=[:unconfirmed
=> :confirmed]>, #<StateMachine::Event name=:trust transitions=
[[:unconfirmed, :confirmed] => :trusted]>]

-------- and here we go:
 x.verify!
StateMachine::InvalidTransition: Cannot transition user_state
via :verify from :unconfirmed

 x.trust!
StateMachine::InvalidTransition: Cannot transition user_state
via :trust from :unconfirmed

on log Im getting only:

SQL (0.0ms)   BEGIN
SQL (1.8ms)   ROLLBACK

but if I use
x.verify false
    ==> true

what Im doing wrong or where is the problem?




best regards
