Send an event in 10s by attribute delay

[Raimundo Santos Moura]

Hi,
 I tried to run the code below, but the attribute <delay> doesn't work well
(seemingly).

 What do i want to do?
    In state "Off", by trigger of the event <ev1>, i need to wait 10s in
state "On"; after this time, i should return to state "Off".

 Is there any error?

 Thanks,
Raimundo Moura
