You imported the class ActionEvent wrong package (AWT). You must import package class javax.faces.event.ActionEvent and not of java.awt.event.ActionEvent.

This error is generated because JSF searched but did not find an appropriate method with that name. It did not know how to pass the parameter (java.awt.event.ActionEvent) of the method salvaFuncionario.

  • Thank you very much, it worked here.

  • @user8465, if this answer is correct for your question, please mark it as resolution for the answer.

  • brand-like ?

  • @user8465, I believe it is just mark the "check" that has below the score.
