PrimeFaces Ajax不起作用

Question

Why, when I use ajax = true the action button primefaces does not work? Whenever this happens to me, someone has the same situation?

<p:commandButton action="#{usuarioBean.insert()}" value="Gravar" 
    icon="/resources/img/accept.ico">
    <p:confirm header="Confirmação" message="Tem Certeza??" icon="ui-icon-alert"/>  
    </p:commandButton>
<p:confirmDialog global="true" showEffect="fade" hideEffect="fade">  
    <p:commandButton value="Sim" type="button" styleClass="ui-confirmdialog-yes" 
    icon="ui-icon-check"/>  
    <p:commandButton value="Não" type="button" styleClass="ui-confirmdialog-no" 
    icon="ui-icon-close"/>       
</p:confirmDialog>

In this case, I need two things and none work.

Sometimes. Some Components can prevent each other .İf like a Button does not work.You have to add process="@this". Directly your button works.

<p:commandButton action="#{usuarioBean.insert()}" value="Gravar"  **process="@this"**
icon="/resources/img/accept.ico">
<p:confirm header="Confirmação" message="Tem Certeza??" icon="ui-icon-alert"/>  
</p:commandButton>
<p:confirmDialog global="true" showEffect="fade" hideEffect="fade">  
<p:commandButton value="Sim" type="button" styleClass="ui-confirmdialog-yes" 
icon="ui-icon-check"/>  
<p:commandButton value="Não" type="button" styleClass="ui-confirmdialog-no" 
icon="ui-icon-close"/>       
</p:confirmDialog>

You should review "action" attribute in commandButton ( action="#{usuarioBean.insert}" ).

<p:commandButton action="#{usuarioBean.insert}" value="Gravar" 
    icon="/resources/img/accept.ico">
    <p:confirm header="Confirmação" message="Tem Certeza??" icon="ui-icon-alert"/>  
</p:commandButton>
