j'ai cette erreur :

SEVERE: Received 'javax.el.MethodNotFoundException' when invoking action listener '#{ratMB.deleteRat}' for component 'j_idt23'
javax.faces.event.MethodExpressionActionListener processAction
SEVERE: javax.el.MethodNotFoundException: Method not found: com.xxxx.beans.RatManagedBean@1481484b.deleteRat()

Quelqu'un saurait-il m'indiquer comment résoudre ce problème ?

Merci d'avance
