问题
I am using EJB 3.0 + JPA 2.0 + PrimeFaces 3.2 + JSF 2.0. The navigation in my application was great with no problems when I repeated the same code in every page. When I template.xhtml I used as a master page so that the same code applies to all pages, an error message comes:
javax.servlet.ServletException: Trying to extract rowIndex from clientId 'j_idt36:j_idt38:j_id2' For input string: "j_idt38"
This link show you when the error message rises: http://www.youtube.com/watch?v=rR6CqwBREpM
template.xhtml code :
<h:head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<script>
window.history.forward();
</script>
<ui:insert name="title">
</ui:insert>
<link href="#{facesContext.externalContext.requestContextPath}/resources/css/cssLayout.css" rel="stylesheet" type="text/css"/>
</h:head>
<h:body>
<f:view locale="#{langueApp.localeCode}">
<p:layout fullPage="true">
<p:layoutUnit position="north" size="100" header="#{bundle.header}" resizable="true" closable="false" collapsible="true">
<ui:include src="template/header.xhtml"/>
</p:layoutUnit>
<p:layoutUnit position="west" size="300" resizable="true" collapsible="true" header="#{bundle.me}" minSize="200">
<ui:include src="template/dynamicmenu.xhtml"/>
</p:layoutUnit>
<ui:insert name="content">
</ui:insert>
<p:layoutUnit position="south" size="0" style="text-align: center;" header="#{bundle.footer}" resizable="false" closable="false" collapsible="false" >
<ui:include src="template/footer.xhtml"/>
</p:layoutUnit>
</p:layout>
</f:view>
</h:body>
the stack trace :

I think this is a bug in Mojarra implementation. I traced down to the error in code and fired a bug: http://java.net/jira/browse/JAVASERVERFACES-2623
