The text with id=txt is inserted outside the commandlink after rerendering.
And therefore the link is broken. A refresh of the page gets it back.
Could somebody please help?
<h:form id="frm">
<h:selectOneMenu value="#{myBean.currentId}">
<f:selectItems value="#{myBean.selectListA}" />
<a4j:support event="onchange" action="#{myBean.changeSomething}"
reRender="priceGroup,idLink" />
</h:selectOneMenu>
<h:panelGroup id="priceGroup">
<a4j:commandLink id="idLink">
<h:outputText id="txt" value="#{myBean.someValue}" />
</a4j:commandLink>

I'm new to jsf, and I'm writing my first application using richfaces. I'm having trouble with the ajax tag that I use to update the associated managed bean property on server for rich:calendar components. This is the code:
<rich:panel header="Computing Options">
<h4>Time Interval</h4>
<h:panelGrid columns="4" width="100%">
<h:outputText value="From" />
<rich:calendar id="intervalFrom" value="#{scenarioEditor.intervalFrom}" popup="true" showApplyButton="true" datePattern="yyy-MM-ddTHH:mm">
<a4j:ajax execute="#this" event="change" render="outFrom" />
</rich:calendar>
<h:outputText value="To" />
<rich:calendar id="intervalTo" value="#{scenarioEditor.intervalTo}" popup="true" showApplyButton="true" datePattern="yyy-MM-ddTHH:mm">
<a4j:ajax execute="#this" event="change" render="outTo" />
</rich:calendar>
<h:outputText id="outFrom" value="From: #{scenarioEditor.intervalFrom}" />
<h:outputText id="outTo" value="To: #{scenarioEditor.intervalTo}" />
</h:panelGrid>
<h4>Algorithms</h4>
<h:panelGrid columns="2">
<h:selectBooleanCheckbox value="#{scenarioEditor.visibilityClashes}" id="clash" >
<f:ajax execute="#this"/>
</h:selectBooleanCheckbox>
<h:outputLabel value="Visibility Clashes Evaluator" for="clash" style="width:170px" />
<h:selectBooleanCheckbox value="#{scenarioEditor.xBandInterference}" id="xband" >
<f:ajax execute="#this"/>
</h:selectBooleanCheckbox>
<h:outputLabel value="X-Band Interferences Evaluator" for="xband" style="width:170px"/>
</h:panelGrid>
</rich:panel>
checkboxes works fine, but the calendars do not. Why? I`ve tried both f:ajax and a4j:ajax without luck.
To better clarify, I want that right after the user has finished entering a value into the calendar, an ajax request is made that call the setter method for the associated property. And this, for the calendar does not happen while for the checkboxes, it does.
The ajax event is failing because of T in datePattern="yyy-MM-ddTHH:mm" is not a valid date formatting pattern. If you add a <rich:messages/> component to your field, you'll see that a conversion error is occurring on each ajax request. Remove the T and you'll be fine
I have the following JSF code in my page
<h:panelGroup id="rSelectionPanel" rendered="#{bean.admin}">
<h4 class="header-line">Admin Panel</h4>
<h:panelGroup rendered="#{bean.selectionMode=='RS'}">
<h:form styleClass="registerForm">
<h:outputLabel value="End Line1?" rendered="#{not bean.endLine2}"></h:outputLabel>
<h:selectBooleanCheckbox id="endLine1" value="#{bean.endLine1}" rendered="#{not bean.endLine2}">
<p:ajax event="change" update=":rSelectionPanel"></p:ajax>
</h:selectBooleanCheckbox>
<h:outputLabel value="End Line2?" rendered="#{not bean.endLine1}"/>
<h:selectBooleanCheckbox id="endLine2" value="#{bean.endLine2}" rendered="#{not bean.endLine1}">
<p:ajax event="change" update=":rSelectionPanel"></p:ajax>
</h:selectBooleanCheckbox>
<h:inputTextarea id="newLine2Name" styleClass="form-poshytip" title="Line2 Name" rows="1" maxlength="50"
value="#{bean.newLine2Name}" validatorMessage="Too many characters" rendered="#{bean.endLine2}">
<f:passThroughAttribute name="placeholder" value="Line2 Name" />
<f:validateLength maximum="50" />
</h:inputTextarea>
<h:commandButton styleClass="submit" value="Select Line" action="#{bean.confirmLineBy}">
</h:commandButton>
</h:form>
</h:panelGroup>
</h:panelGroup>
With the following backing bean java code
public void confirmLineBy(){
getLog().debug("Entering confirmLineBy....");
ConfirmLineByRequest request = new ConfirmLineByRequest();
request.setPage(getPage());
request.setEndLine1(endLine1);
if(isEndLine2())request.setNewLine2Name(newLine2Name);
request.setEndLine2(isEndLine2());
ConfirmLineByResponse response = LineService.confirmLineBy(request, null);
nextUnconfirmedLines.removeAll(nextUnconfirmedLines);
setConfirmedLines(response.getConfirmedLines());
setLine2s();
setAddedLine(false);
getLog().debug("CONFIRMED LINES SIZE: "+confirmedLines.size());
getLog().debug("Exiting confirmLineBy....");
}
When clicking the commandButton with neither of the boxes checked, it submits fine. But when checking either of the checkboxes, it doesn't even call bean.confirmLineBy().
Any ideas?

I am trying to update a selectOneMenu from the results of another selectOneMenu.
When group is selected the user menu should be updated.
I have verified that the data for the user menu is being updated. It is not being rendered however.

You should not perform business logic in getters/setters. They are invoked multiple times in JSF lifecycle and are intented to get and set the property. You should perform business logic in action(listener) methods instead.
The following construct should work:
<h:selectOneMenu id="group" value="#{projectBean.transferUtil.selectedTransferGroup}" >
<f:selectItems value="#{projectBean.transferUtil.transferGroups}" />
<f:ajax execute="group" listener="#{projectBean.transferGroupChanged}" render="user" />
</h:selectOneMenu>
<h:selectOneMenu id="user" value="#{projectBean.transferUtil.selectedTransferUser}" required="true" requiredMessage="Select User" >
<f:selectItems value="#{projectBean.transferUtil.transferUsers}" />
</h:selectOneMenu>
With
public void transferGroupChanged(AjaxBehaviorEvent event) {
// Change the transferUsers here.
}
The getters and setters should not contain any business logic. They should merely get and set the property.

How to load and display dependent h:selectOneMenu on change of a h:selectOneMenu
I have a popup with three tabs in primefaces tabPanel. In the middle is a table called "composicao", this tab is rendered when user marks checkbox that is located in first tab.
The tables have a lot of inputs, selects and checkboxes that user can fill in any order, so if the user fill all fields and then mark the checkbox, all fields are cleared cause that checkbox update the tabView. I tryied set some fields immediate attribute to true and set p:ajax process attribute to #all, but with this approach nothing happens.
This is the code of tabPanel:
<h:panelGroup id="abasCadastroProduto">
<p:tabView>
<p:tab title="base">
<ui:include src="../../tabs/abaEdicaoBaseProduto.xhtml"/>
</p:tab>
<p:tab id="abaComposicao" title="composicao" rendered="#{produto.composto}">
<ui:include src="../../tabs/abaEdicaoComposicaoProduto.xhtml"/>
</p:tab>
<p:tab
title="tributacao">
<ui:include src="../../tabs/abaEdicaoTributacaoProduto.xhtml"/>
</p:tab>
</p:tabView>
</h:panelGroup>
this is part of the code of first tab:
<h:panelGroup layout="block">
<p:fieldset legend="geral">
<h:panelGroup layout="block">
<h:selectBooleanCheckbox id="produtoAtivoCheck"
value="#{produto.ativo}"/>
<h:outputLabel value="ativo" for="produtoAtivoCheck"/>
<h:selectBooleanCheckbox id="produtoMovimentoCheck"
value="#{produto.movimentaEstoque}"/>
<h:outputLabel value="movimento" for="produtoMovimentoCheck"/>
<!-- THIS IS THE CHECKBOX -->
<h:selectBooleanCheckbox id="produtoCompostoCheck"
value="#{produto.composto}">
<p:ajax event="change" update="abasCadastroProduto" process="#all"/>
</h:selectBooleanCheckbox>
<h:outputLabel value="composto" for="produtoCompostoCheck" />
</h:panelGroup>
.......
<h:panelGroup layout="block">
<h:outputLabel value="descricao"/>
<p:inputText value="#{produto.descricao}" required="true" immediate="true"
requiredMessage="obrigatorio"/>
<h:outputLabel value="complemento"/>
<p:inputText value="#{produto.descricaoComplementar}"/>
</h:panelGroup>
......
</p:fieldset>
</h:panelGroup>
Is there a way I can solve this problem??
I think is unnaceptable to user see fields they spend some time to fill, been cleared when you click in a checkbox...
Solved.
The problem was validation of required fields, so I've created a REQUIRED parameter and set it to false when user clicks checkbox:
<h:selectBooleanCheckbox id="produtoCompostoCheck"
value="#{produto.composto}" styleClass="popup-produto-geral-check">
<f:param name="REQUIRED" value="false"/>
<f:ajax event="change" immediate="true" render="abasCadastroProduto" execute="#form" />
</h:selectBooleanCheckbox>
<h:selectOneMenu value="#{produto.idClasse}" immediate="true"
required="#{param['REQUIRED']}" validatorMessage="#{cadastroMsg['popup.cadastro.produto.base.classe.invalido']}"
requiredMessage="#{cadastroMsg['popup.cadastro.produto.base.classe.obrigatorio']}">
<f:selectItems value="#{selectItemClasse.itens}"/>
<f:ajax event="change" immediate="true" render="selectSubclasse"/>
</h:selectOneMenu>
and I've made submit button set "REQUIRED" parameter to true.
instead of this:
<p:ajax event="change" update="abasCadastroProduto" process="#all"/>
try this:
<p:ajax render="#form" />
I'm creating a dataTable with two dataTable inside :).
But this time I'm having problem to render it when I try use binding attribute in a h:panelGroup that wraps first dataTable.
I'm using binding to help refresh just the panelGroup, like BalusC told in this question. When I remove the binding attribute the dataTable renders normally, but of course nothing is rendered with f:ajax tags inside the dataTables.
Here is the xhtml:
<ui:component>
<h:panelGroup>
<h:panelGroup layout="block;" id="#{id}"
binding="#{painelTabelaContatos}" rendered="true">
<p:dataTable id="tabela#{id}"
value="#{modeloTabelaContatos.listaDeContatos}" var="contato"
selectionMode="single"
rowSelectListener="#{controladorTabelaContatos.processarSelecaoLinha}"
rowUnselectListener="#{controladorTabelaContatos.processarDeselecaoLinha}"
selection="#{modeloTabelaContatos.contatoSelecionado}">
<p:column headerText="Contatos">
<hrgi:editableText style="width:100%" value="#{contato.descricao}" />
</p:column>
<p:column headerText="Telefones">
<h:dataTable value="#{contato.telefones}" var="telefone">
<h:column>
<h:inputText value="#{telefone}" />
</h:column>
<h:column>
<h:graphicImage library="img" name="default_trash.png"
style="cursor:pointer;">
<f:ajax event="click" render=":#{painelTabelaContatos.clientId}"
listener="#{controladorTabelaContatos.removerTelefone(contato, telefone)}" />
</h:graphicImage>
</h:column>
</h:dataTable>
</p:column>
<p:column headerText="e-mails">
<h:dataTable value="#{contato.emails}" var="email">
<h:column>
<h:inputText value="#{email}" />
</h:column>
<h:column>
<h:graphicImage library="img" name="default_trash.png"
style="cursor:pointer;">
<f:ajax event="click" render=":#{painelTabelaContatos.clientId}"
listener="#{controladorTabelaContatos.removerEmail(contato, email)}" />
</h:graphicImage>
</h:column>
</h:dataTable>
</p:column>
<p:column>
<h:graphicImage library="img" name="default_trash.png"
style="cursor:pointer;">
<f:ajax render=":#{painelTabelaContatos.clientId}" event="click"
listener="#{controladorTabelaContatos.removerContato(contato)}" />
</h:graphicImage>
</p:column>
</p:dataTable>
</h:panelGroup>
<h:panelGroup layout="block">
<p:commandButton value="ADICIONAR CONTATO" update="#{id}"
immediate="true"
action="#{controladorTabelaContatos.adicionarContato}" />
<p:commandButton value="ADICIONAR TELEFONE" update="#{id}"
immediate="true"

I've already tried remove the h:dataTables that are inside p:dataTable, but without success.
This component is just the content of a PrimeFaces tab, and this tab is inside a PrimeFaces dialog. Could someone explain me why is this happening??
I've found the cause of error, after it was easy find a solution...
The problem is caused because I call this component in two different pages:
popupCadastroPessoa.xhtml
<ui:include src="../tabs/abaEdicaoContatos.xhtml">
<ui:param name="id" value="painelContatoPessoa" />
</ui:include>
and in popupCadastroFuncionario.xhtml
<ui:include src="../tabs/abaEdicaoContatos.xhtml">
<ui:param name="id" value="painelContatoFuncionario" />
</ui:include>
cause I didn't really created the binding bean, JSF gets confused. So I've just created two UIPanel beans and passed it as parameter:
<ui:include src="../tabs/abaEdicaoContatos.xhtml">
<ui:param name="id" value="painelContatoPessoa" />
<ui:param name="painelTabelaContatos" value="#{bindingTabelaContatoPessoa}"/>
</ui:include>
Was my fault. Thanks for your attention and sorry for the inconvenience.
