我无法在h:selectOneMenu不验证其他输入的情况下立即提交.这是代码:
<h:selectOneMenu value="#{a.avalue}" onchange="submit()" immediate="true">
<f:selectItems value="#{b.bvalue}" var="k" itemLabel="#{k.asdad}"
itemValue="#{k.asdad}"/>
</h:selectOneMenu>
<h:inputText id="sada" value="#{c.cvalue}" required="true"
requiredMessage="*asdadadadasd"
validatorMessage="*asdsadadadadad">
<f:validateLength maximum="80"/>
</h:inputText>
当我更改菜单值时,其他输入的验证器仍然会激活.我怎么能否认呢？
<ui:define name="description" rendered="false">
<meta name="description" content="do not render" />
</ui:define>
我在我的xhtml页面中使用此代码,当我运行应用程序时,元描述仍在渲染.我想根据某些条件使用元描述标签.主布局:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html">
<h:head>
<ui:insert name="description" />
</h:head>
...........
</html>

我在那里读过,但我不能从primefaces datatable cellEditor获取编辑值,它给了我未经编辑的值.我正在使用jpa.xhtml页面:
