我有表面形式
<h:form id="profileGridForm">
<h:panelGroup>
<p:inplace id="myid" editor="#{bean.changeLangEnabled}">
<h:selectOneMenu value="#{bean.changedBillingLanguage}">
...
</h:selectOneMenu>
</p:inplace>
</h:panelGroup>
<h:panelGroup>
<p:commandButton value="Model" update="modelForm" action="#{modelBean.clear}" ajax="true"
oncomplete="PF('showModel').show()"/>
</h:panelGroup>
</h:form>
当我按下Model按钮时,调用ChangedBillingLanguage方法。如何在表格内按按钮时不发送表格?
