Problemas para atualizar inputText usando <a4j:support>

Front-end
#1

Estou usando a implementação Oracle ADF com Ajax4JSF.

No seguinte trecho de código

<af:inputText id="iptValorBruto" simple="true" columns="12" maximumLength="12" 
			binding="#{protocolarNovoPagamentoPJForm.bindValorBruto}"
			partialTriggers="cbSetaValorBruto"
			onkeydown="return(currencyFormat(this,event))">
			<af:convertNumber pattern="###,###,###,###,##0.00"/>
			<a4j:support event="onblur" 
			reRender="optPercPISPASEP,
					  optPercCOFINS,
					  optPercCSLL,
					  optPercISS,
					  optValorBruto,
					  optValorDescontadoPISPASEP,
					  optValorDescontadoCOFINS,
					  optValorDescontadoCSLL,
					  optValorPISPASEP,
					  optValorPISPASEP,
					  optValorCSLL,
					  optValorIR,
					  optValorINSS,
					  optValorISS,
					  optValorLiquido,
					  iptValorINSS"
					  ajaxSingle="true"
					  limitToList="true"
					  immediate="true"
					  action="#{protocolarNovoPagamentoPJForm.setaValorBruto}"/>
</af:inputText>

Onde no parâmetro reRender todos os ids que comecao com “opt” são OutputText e o iptValorINSS
é um inputText com um CoreInputText associado.

Se eu tiro o iptValorINSS tudo funciona, mas quando eu adiciono o inputText ocorre um NullPointException.

Sei muito pouco sobre Ajax4JSF.

Alguém pode me explicar como é possível atualizar valores de um inputText?

Obrigado!

#2

Algo que percebi que soa de maneira estranha é que se eu utilizo
af:form, o erro só ocorre quando eu tento atualizar o valor do inputText.
Mas quando eu substituo por a4j:form a exceção é lançada logo que a página é carregada.

Valeu!

Oi Rafael,

em uma aplicação fiz um lógica igual a sua e deu certo. Estou usando JSF-Ri + RichFaces e Ajasx4jsf

[code]<h:inputText id=“custo” value="#{bean.valor}">
<a4j:support event=“onblur” focus=“ipi”
action="#{bean.calcular}"
reRender=“ipi” />
</h:inputText>

<h:outputText value=“Ipi:” />
<h:inputText id=“ipi”
value="#{bean.ipi}" />[/code]

Será que o valor que vc está setando para o inputText está nulo?

#4

Engraçado que depois eu fiz um exemplo mais simples em casa usando o próprio ADF e deu certo.
Estava com receio de ser um problema de incompatibilidade entre o ADF e o Ajax4JSF.

Talvez seja algum problema relacionado ao conversor dentro da tag

#5

Eu tirei o af:convertNumber e o paramêtro onkeydown=“return(currencyFormat(this,event))” do inputText
e funcionou!!!
