Ubuntu ApacheTomcat+；JSF+；Primefaces:Ajax更新导致表单失败
我的环境是：Ubuntu ApacheTomcat+；JSF+；Primefaces:Ajax更新导致表单失败,ubuntu,jsf-2,primefaces,tomcat7,netbeans-7,Ubuntu,Jsf 2,Primefaces,Tomcat7,Netbeans 7,我的环境是： PrimeFaces:3.1.1 服务器：Apache Tomcat 7.0.34.0 JSF:Mojarra 2.2.0 JDK:1.7.0_25 IDE:Netbeans 7.3.1 所以：Linux Ubuntu 13.04 64位 我有以下情况： 在我的xhtml中有一个包含多个组件的表单。其中一个组成部分如下所示： <h:panelGrid columns="4" rendered="#{!inputControlador.tipoDocumento
PrimeFaces:3.1.1
服务器：Apache Tomcat 7.0.34.0
JSF:Mojarra 2.2.0
JDK:1.7.0_25
IDE:Netbeans 7.3.1
所以：Linux Ubuntu 13.04 64位
我有以下情况：
在我的xhtml中有一个包含多个组件的表单。其中一个组成部分如下所示：
<h:panelGrid columns="4" rendered="#{!inputControlador.tipoDocumentoPessoa()}">
<p:autoComplete value="#{inputControlador.movimentacao.fornecedor}"
completeMethod="#{inputControlador.completaPjs}"
id="fornecedor"
rendered="#{!inputControlador.tipoDocumentoPessoa()}"
size="50"
var="pj"
itemLabel="#{pj}"
itemValue="#{pj.id}"
forceSelection="true"
converter="#{inputControlador.converterPJ}"
onkeydown="cleanCampos(this.id)">
<p:ajax event="itemSelect"
listener="#{inputControlador.primeiraCategoria}"
update="@form"/>
</p:autoComplete>
...
</h:panelGrid>
这是一种非常奇怪的行为，只发生在这个页面、这个组件上。可以是几件事。如何在web.xml中设置javax.faces.STATE_SAVING_方法？如果这是服务器，请尝试客户端。然后你遇到了一个可序列化的问题。如果你没有发布所有的支持bean，那么我们可以检查那里是否有错误。NullPointerException-这是一个大红灯，表明你的错误与ubuntu或netbeans无关。检查给定行中的PrimeFaces代码，但在90%时“#{inputControlador.completaPjs}”返回null。
