si me pudieran ayudar lo agradecería mucho.

Al parecer ya tienes creado ese inout en el formulario o estas creando de nuevo el formulario y ya lo tienes en memoria.
Revisa si el bena que estas usando tiene ambito por sesion y no por request. Tambien puede ser que este bean este compartido entre multiples vistas asi que hazlo solo que tenga el ambito por vista...
