Primefaces日历侦听器 - 错误[io.undertow.request]

我正在尝试在Calendar上使用监听器 . 我正在做以下事情：

• lista.xhtml

<p:outputLabel for="data" value="Data:" />
<p:calendar id="data" value="#{movimentacaoBean.movimentacao.data}" locale="pt_BR" pattern="dd/MM/yyyy" mask="true">
   <p:ajax event="dateSelect" update="" listener="#{movimentacaoBean.definePeriodo}" />
</p:calendar>

• MovimentacaoBean

public void definePeriodo（）{System.out.println（“entrou”）; }

我收到以下错误

Update

如果我在其他字段上使用相同的侦听器（例如，带有blur事件的inputText），它的效果很好！

Update I

我试过这样做但没有用

public void definePeriodo(SelectEvent event){
    System.out.println("entrou");
}
