Jsf: Mudar styleClass/style dinamicamente

1)Alteração completa do StyleClass

<h:outputText
   value="#{bean.processo.statusProcesso}"
   styleClass="#{bean.processo.cancelado == false ? 'textoRelatorio' : 'labelRelatorio'}"/>

2) Alteração parcial do Syle

<h:outputText value=" - "

  style="font-weight:bold;color:#{processo.flp_cor};" />

JavaScript: Pegar o valor de um h:selectOneMenu e passar para um h:inputHidden

<f:subview id="sviewGrafico">
<rich:panel styleClass="panelPrincipal">
<rich:toolBar>
<h:form id="formGrafico" prependId="false">
<h:outputText value="Grupo:" />

<h:selectOneMenu value="#{graficoData.id}" id="selectGrupo"
onchange="(document.getElementById('sviewGrafico:ihCodigoGrupo').value =                                        document.getElementById('sviewGrafico:selectGrupo').value)">
<f:selectItems value="#{relatorioPerformanceMB.comboGrupo}"/>
</h:selectOneMenu>

<h:inputHidden value="#{relatorioPerformanceMB.codigoGrupo}" id="ihCodigoGrupo"/>

<h:commandButton value="Gerar" />

<a4j:commandButton value="Visualizar Relatório"
actionListener="#{relatorioPerformanceMB.gerarGrafico}"/>

</h:form>
</rich:toolBar>


<a4j:mediaOutput element="img" cacheable="false" session="true"
   createContent="#{relatorioPerformanceMB.paint}" 
   value="#{graficoData}" rendered="#{graficoData.id != null}"
   mimeType="image/jpeg"/>

</rich:panel>
</f:subview>

Causa: Tentar passar um objeto no actionparam

<a4j:actionparam id="deleteContainer" value="#{con}" name="delteteCont"/>

Solução: Passar apenas o id
<a4j:actionparam id="deleteContainer" value="#{con.id}" name="delteteCont"/>

Cannot convert onload of type class java.lang.String to class org.richfaces.component.JQueryTiming

No Jsf 1.2/Richfaces 3.3 você poderia fazer dessa forma:

<h:inputText  id="dataVencimento" >
        <rich:jQuery selector="#dataVencimento" query="mask('99/99/9999')" timing="onload" />
</h:inputText>

No Jsf 2.0/Richfaces 4.1 o rich:query não pode ficar dentro do h:inputText e o timing mudou:


<h:inputText  id="dataVencimento" />
<rich:jQuery selector="#dataVencimento" query="mask('99/99/9999')" timing="domready" />

Windows 7 / Vista ingressar em domínio Windows 2008

É necessário as seguintes alterações no registro do windows 7 / Vista:

Utilize o regedit.exe e faça as seguintes modificações no registro do Windows. (Adicione o que faltar ou altere se já existir)

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanWorkstation\Parameters
DWORD32 - DomainCompatibilityMode = 1
DWORD32 - DNSNameResolutionRequired = 0

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Netlogon\Parameters
DWORD32 - RequireSignOnSeal = 0
DWORD32 - RequireStrongKey = 0


Tente entrar no domínio após efetuar as alterações. Não é necessário reiniciar o Windows após as alterações no regedit!
