Olá pessoal,

Estou começando agora com JSF depois de um longo e tenebroso inverno de Struts e estou com uma dúvida que está me tirando o sono faz dias!!!

Quero inserir uma página dinamicamente através de um Menu, daqueles estilinhos básicos (Menu a esquerda + Cabeçalho + COnteúdo a direita).
Para começar estou apenas tentando inserir uma página externa através da tag <a4j:include> desta maneira:
Página Teste que irá conter uma outra (o menu):

&lt;?xml version=&quot;1.0&quot; encoding=&quot;ISO-8859-1&quot;?&gt;
&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt;

&lt;ui:composition	xmlns="http://www.w3.org/1999/xhtml"
				xmlns:h="http://java.sun.com/jsf/html"
				xmlns:f="http://java.sun.com/jsf/core"
				xmlns:ui="http://java.sun.com/jsf/facelets"
				xmlns:rich="http://richfaces.org/rich"
				xmlns:richfaces="http://richfaces.ajax4jsf.org/rich"
				xmlns:ajax="https://ajax4jsf.dev.java.net/ajax"
				xmlns:a4j="http://richfaces.org/a4j"&gt;
	&lt;f:view id="teste"&gt;
		&lt;h:outputText value="teste aqui;;;" /&gt;
		
		&lt;a4j:outputPanel&gt;
			&lt;ajax:include viewId="/pages/menu.xhtml" /&gt;
		&lt;/a4j:outputPanel&gt;
		
	&lt;/f:view&gt;
&lt;/ui:composition&gt;

Abaixo seria a página do menu:

&lt;?xml version=&quot;1.0&quot; encoding=&quot;ISO-8859-1&quot;?&gt;  
&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt;

&lt;ui:composition	xmlns="http://www.w3.org/1999/xhtml"

				xmlns:f="http://java.sun.com/jsf/core"
				xmlns:rich="http://richfaces.org/rich"
				xmlns:richfaces="http://richfaces.ajax4jsf.org/rich"
				xmlns:ajax="https://ajax4jsf.dev.java.net/ajax"
				xmlns:a4j="http://richfaces.org/a4j"&gt;
&lt;f:subview id="subMenu"&gt;
	&lt;rich:panelMenu style="width:200px" mode="ajax"
		iconExpandedGroup="disc" iconCollapsedGroup="disc"
		iconExpandedTopGroup="chevronUp" iconGroupTopPosition="right"
		iconCollapsedTopGroup="chevronDown"&gt;
		&lt;rich:panelMenuGroup label="Ponto Eletrônico"&gt;
			&lt;rich:panelMenuItem label="Marcar"
				action="#{marcaPonto.getPontoEletronico}"&gt;
				&lt;a4j:keepAlive beanName="marcaPonto" /&gt;
				&lt;f:param name="current" value="Item 1" /&gt;
			&lt;/rich:panelMenuItem&gt;
		&lt;/rich:panelMenuGroup&gt;
		&lt;rich:panelMenuGroup label="Group 2"&gt;
			&lt;rich:panelMenuItem label="Item 2.1" action="#"&gt;
				&lt;f:param name="current" value="Item 2.1" /&gt;
			&lt;/rich:panelMenuItem&gt;
			&lt;rich:panelMenuItem label="Item 2.2" action="#"&gt;
				&lt;f:param name="current" value="Item 2.2" /&gt;
			&lt;/rich:panelMenuItem&gt;
			&lt;rich:panelMenuItem label="Item 2.3" action="#"&gt;
				&lt;f:param name="current" value="Item 2.3" /&gt;
			&lt;/rich:panelMenuItem&gt;
			&lt;rich:panelMenuGroup label="Group 2.4"&gt;
				&lt;rich:panelMenuItem label="Item 2.4.1" action="#"&gt;
					&lt;f:param name="current" value="Item 2.4.1" /&gt;
				&lt;/rich:panelMenuItem&gt;
				&lt;rich:panelMenuItem label="Item 2.4.2" action="#"&gt;
					&lt;f:param name="current" value="Item 2.4.2" /&gt;
				&lt;/rich:panelMenuItem&gt;
				&lt;rich:panelMenuItem label="Item 2.4.3" action="#"&gt;
					&lt;f:param name="current" value="Item 2.4.3" /&gt;
				&lt;/rich:panelMenuItem&gt;
			&lt;/rich:panelMenuGroup&gt;
			&lt;rich:panelMenuItem label="Item 2.5" action="#"&gt;
				&lt;f:param name="current" value="Item 2.5" /&gt;
			&lt;/rich:panelMenuItem&gt;
		&lt;/rich:panelMenuGroup&gt;
		&lt;rich:panelMenuGroup label="Group 3"&gt;
			&lt;rich:panelMenuItem label="Item 3.1" action="#"&gt;
				&lt;f:param name="current" value="Item 3.1" /&gt;
			&lt;/rich:panelMenuItem&gt;
			&lt;rich:panelMenuItem label="Item 3.2" action="#"&gt;
				&lt;f:param name="current" value="Item 3.2" /&gt;
			&lt;/rich:panelMenuItem&gt;
			&lt;rich:panelMenuItem label="Item 3.3" action="#"&gt;
				&lt;f:param name="current" value="Item 3.3" /&gt;
			&lt;/rich:panelMenuItem&gt;
		&lt;/rich:panelMenuGroup&gt;
	&lt;/rich:panelMenu&gt;
&lt;/f:subview&gt;	
&lt;/ui:composition&gt;

Tudo funciona perfeitamente sozinho, mas quando coloco a chamada Ajax dentro da primeira página dá o seguinte erro:

guimoz 23 de mar. de 2009

eu to usando a mesma estrutura q vc, tenho varios includes na minha pagina, e o menu, remete uma string url, pra um include, exemplo…

item do menu <f:param id="url" value="endereçoDoXhtml"/>

e na pagina q vai exibir o conteudo tenho um include do facelets(alias, todos os includes q fasso sao com o facelets), que pega o valor da url atravez do metodo do mb …

<a4j:outputPanel ajaxRendered="true"> <ui:include src="#{meuMB.url}"/> </a4j:outputPanel>

a diferença é q eu tenho os includes do facelets, uso eles pq, tive alguns problemas com includes em cascata utilisando o a4j, alguns metodos n eram chamados utilisando o a4j:include.

Joseph_Climber 23 de mar. de 2009

Olá pessoal,

Primeiro quero agradecer ao “guimoz” pela atenção… a dica valeu para outra dúvida sim, mas neste caso eu continuei utilizando a tag do Ajax mesmo!

Os problemas eram dois:

<a4j:keepAlive beanName="marcaPonto" /> <f:param name="current" value="Item 1" />

O Bean não estava com escopo de sessão e o parâmetro passado com o name “current” nem existia… falta de atenção!

Mais uma vez obrigado pela ajuda!

Abraço!

Preciso de ajuda, pois procurei exemplos e ainda não achei nenhum.

abs,

aprender a usar as tags é fundamental para que o pessoal se anime a ler seu código

assim chega a ser triste…

abraços!!!
