尝试update="growl"没有任何格式ID它应该有效。如果您有任何问题，请告诉我。如果您想要对多个组件进行ajax更新，可以使用update="growl,secondid,thirdid"
请托盘此代码并告诉我它是否正常工作？
<h:form id="form">
<p:panel id="panel" header="New Person" style="margin-bottom:10px;">
<p:messages id="messages" />
<h:panelGrid columns="3">
<h:outputLabel for="firstname" value="Firstname: *" />
<p:inputText id="firstname"
value="#{pprBean.firstname}" required="true" label="Firstname">
<f:validateLength minimum="2" />
</p:inputText>
<p:message for="firstname" />
<h:outputLabel for="surname" value="Surname: *" />
<p:inputText id="surname"
value="#{pprBean.surname}" required="true" label="Surname"/>
<p:message for="surname" />
</h:panelGrid>
</p:panel>
<p:commandButton value="Ajax Submit" update="panel,display" id="ajax"
actionListener="#{pprBean.savePerson}" />
<p:commandButton value="Non-Ajax Submit" actionListener="#{pprBean.savePerson}"
ajax="false" />
<p:commandButton value="With Icon" actionListener="#{pprBean.savePerson}" id="withIcon"
update="panel,display" icon="ui-icon-disk" />
<p:commandButton actionListener="#{pprBean.savePerson}" update="panel,display" id="iconOnly"
icon="ui-icon-disk" title="Icon Only"/>
<p:commandButton value="Disabled" disabled="true" id="disabled" />
