You are extremely short today. I am not sure I know why your fields are dirty.

[lgweb]

Why?

[lgweb]

even create a new object when the fields are still dirty, not clean in any way
,:(

as Sergey already told you - it will be better to show us your code and explain more carefull the case you've implemented.

but I understand it, see it with my bean scope of sitting on a page have a tabeddPanel this tabeddPanel a tab displays a list of items and another tab displays a form of registration, I have two buttons one saves a register and changes to the tab list and tab in the new list have a button that sends the tab to register, but the tab record the old data are still there, and on the bean was created a new object.
see snippets of code:

<rich:tabPanel switchType="client" id="tabpaneln"
title="Numeracao" label="Numeracao"
selectedTab="#{produto.tabSet}" rendered="#{!produto.viewState}" immediate="true">
<rich:tab label="Numeracao" immediate="true" id="tbnumeracao"
ajaxSingle="true">
<rich:datascroller align="center" for="tbprodnum" maxPages="20"
style=" width : 600px;" />
<rich:dataTable
onRowMouseOver="this.style.backgroundColor='#F1F1F1'"
onRowMouseOut="this.style.backgroundColor='#{a4jSkin.tableBackgroundColor}'"
cellpadding="0" cellspacing="0" rows="5" width="650"
 border="4" var="iv" value="#{produto.modelpn}" id="tbprodnum"
 style=" width : 736px;">
<f:facet name="header">
 <rich:columnGroup>
<rich:column rowspan="2">
<h:outputText value="#{msg.acoes}"></h:outputText>
<rich:separator height="12" styleClass="tooltip"></rich:separator>
<a4j:commandLink id="novopn" action="#{produto.novopn}"
 immediate="true" reRender="tabpaneln">

... This Second Tab

 <rich:tab label="Cadastrar" ajaxSingle="true" immediate="true" id="tbcad">
 <rich:panelBar height="245" width="712">
 <rich:panelBarItem label="#{msg.pedidos}">
 <h:panelGrid columns="2" width="455">
 <h:outputText value="#{msg.numeracao}"></h:outputText>
 <h:panelGroup>
 <h:selectOneMenu
 value="#{produto.produtoNumeracao.numeracao}" required="true"
 id="combo">
<f:selectItems value="#{produto.numeracaoids}" />
 <f:converter converterId="numeracaoconversor" />
 </h:selectOneMenu>
<a4j:commandLink style="cursor:pointer" action="#{numeracao.novo}"
 immediate="true" ajaxSingle="true" ignoreDupResponses="true"
 oncomplete="Richfaces.showModalPanel('loadNumeracao')" >
<h:graphicImage value="/images/newButtons/add.png" width="20"
 height="20" style="border:0" >
 </h:graphicImage>
 </a4j:commandLink>
</h:panelGroup>

 <h:outputText value="#{msg.qtdatual}"></h:outputText>
 <h:inputText value="#{produto.produtoNumeracao.qtdatual}"
 label="Numeração" maxlength="3" required="true"
 id="num"onkeypress="mascara(this,soNumeros)">
 <f:validateLongRange minimum="0" maximum="999"/>
 </h:inputText>

 <h:outputText value="#{msg.qtdmin}"></h:outputText>
 <h:inputText value="#{produto.produtoNumeracao.qtdminima}"
 id="qtdmin" style=" width : 198px;" onkeypress="mascara(this,soNumeros)">
 <f:validateLongRange minimum="0" maximum="999"/>
 </h:inputText>



 <h:outputText value="#{msg.qtdmax}"></h:outputText>
 <h:panelGroup>
 <h:inputText value="#{produto.produtoNumeracao.qtdmaxima}"
 onkeypress="mascara(this,soNumeros)"
 style=" width : 198px;" required="true" id="qtdmax" onblur="return checkQtd()">
 <f:validateLongRange minimum="0" maximum="999"/>
 </h:inputText>

 </h:panelGroup>
 </h:panelGrid>
 <center>
 <a4j:commandButton
 action="#{produto.createpn}" value="salvar" id="salvar" reRender="tbprodnum,tabpaneln" >
 <f:setPropertyActionListener target="#{produto.id}"
 value="#{produto.produto.produtoid}" />
 </a4j:commandButton>

These are the methods in the bean called by the buttons
(<a4j:commandButton action="#{produto.createpn}" value="salvar" id="salvar")

(<a4j:commandLink id="novopn" action="#produto.novopn}")

public String novopn() {
 produtoNumeracao = new ProdutoNumeracao();
 setTabSet("tbcad");
 return "";
 }


public String createpn() {
 if(produtoNumeracao.getQtdmaxima()<produtoNumeracao.getQtdminima()){
 mensagem("chekqtd");
 return null;
 }else{
 IDaoProdutoNumeracao ldao = new DaoProdutoNumeracao();
 ProdutoNumeracaoPK pnpk = new ProdutoNumeracaoPK(produto.getProdutoid()
 ,produtoNumeracao.getNumeracao().getNumeracaoid());
 produtoNumeracao.setProdutoNumeracaoPK(pnpk);
 ldao.salvar(produtoNumeracao);
 setTabSet("tbnumeracao");
 // somaTotalPares();
 getTodosProdutoNumeracao();
 return "";
 }

 }

The only problem I'm having and that the old values remain in the form of registration, even when it created a new object.
Thank you all for your attention, hugging.

Not sure if this is related, but...

I have seen a problem where old values unexpectedly hang around in text fields when using a4j. While debugging, I stepped into the JSF RI and found that the value binding had the correct, new value, but the HtmlInput will display the submitted value if it has it (in this case, the old value). Not sure if this is a bug or not, but it was unexpected behavior from my point of view, because my model changed, and I rerendered a region, but I still got old values.

To work around this, I put my a4j button in a little a4j region and set it up as ajaxSingle. This way, the request values for the other fields on the form weren't applied to the HtmlInputs, and so they properly rendered the value of their binding again.

I don't fully understand that problem, but I thought I'd throw it out there.

Hello friend, thank you follow their instructions and managed to achieve a satisfactory result using a (<a4j: region),
thank you very much, hugging. :)

First off, the behaviour is very expected, because is is a core JSF behaviour.
RichFaces (aka a4j) adds nothing to the scene.

Why JSF works like that is illustrated in the RichFaces' cookbook article:
http://wiki.jboss.org/wiki/RichFacesTwoInputText


People wonder about form cleaning from the very beginning.
This is a form post that was 4 (four!) years ago:
http://forum.java.sun.com/thread.jspa?forumID=427&threadID=528778

Not RichFaces, but even, nor Ajax words were officially pronounced yet.

Thanks Sergey - that's good info.
