[RESOLVIDO] javax.el.MethodNotFoundException. Problemas ao tentar executar um método de um MB

Front-end
#1

Bom dia pessoal,

eu não estou enxergando esse erro em meu código.

aqui tenho meu dataTable


<rich:dataTable id="listaDespesas" rowClasses="even,odd" value="#{veiculoIndividualRelatorioBean.listaDespesas}" var="despesa" rows="10">
	<f:facet name="header"><h:outputLabel value="DESPESAS ADICIONAIS"/></f:facet>

<rich:column >
	<f:facet name="header"><h:outputLabel value="Descricao"/></f:facet>
	<h:inputText value="#{despesa.descricao}"/>
</rich:column>

<rich:column >
	<f:facet name="header"><h:outputLabel value="valor"/></f:facet>
	<h:inputText value="#{despesa.valorDespesa}"/>
</rich:column>

<rich:column >
	<f:facet name="header"><h:outputLabel value=""/></f:facet>
	<a4j:commandButton image="/images/bota_adicionar.png" action="#{veiculoIndividualRelatorioBean.instanciaDespesa}" reRender="listaDespesas"/>
</rich:column>


</rich:dataTable>

Aqui meu método do MB


	public void instanciaDespesa(ActionEvent event){
		
		this.listaDespesas.add(new Despesas());
	}

E aqui está o meu erro:

Alguém pra dar uma força ?

#2

problema resolvido pessoal.

A falta de atenção + a madrugada te faz ficar CEGO.

era simplemente mudar o action para actionListener no método do a4j:commandButton conforme codigo abaixo:


	<a4j:commandButton image="/images/bota_adicionar.png" actionListener="#{veiculoIndividualRelatorioBean.instanciarDespesa}" reRender="listaDespesas"/>

… ehehehehehehhe
