JSF-PrimeFaces - Erro ao tentar injetar ajax via linha de cód.(AjaxBehavior)

Front-end
#1

Estou criando um componente dinâmico e preciso em um inputText ele insira um ajax com keyup, mais ele gera um erro louco e tentei milhões de formas diferentes de fazer acontecer e nada! Se alguém souber como funcionar certinho vou agradecer :smiley:

O erro ocorre quando tente executar o ajax, ou seja somente quando eu digito algo e ele tenta executar o keyup!

Criando MethodExpression

public static MethodExpression criarMethodExspression(String valor, Class classe) { ExpressionFactory factory = FacesContext.getCurrentInstance() .getApplication().getExpressionFactory(); ELContext elContext = FacesContext.getCurrentInstance().getELContext(); return factory.createMethodExpression(elContext, valor, void.class, new Class<?>[] { classe }); }

Linha do InputText e AjaxBehavior

[code]InputText input = new InputText();
input.setValueExpression(“style”,
CControleGeral.criarValueExpression(“width:100%”, String.class));
input.setValueExpression(“value”, CControleGeral.criarValueExpression(
run.getBeanFiltroPesquisa(), String.class));

	AjaxBehavior ajaxBehavior = new AjaxBehavior();
	
	MethodExpression expression = CControleGeral.criarMethodExspression("#{bBuscaCliente.keyUpPesquisa}", ActionEvent.class);
	
	AjaxBehaviorListenerImpl ajaxBehaviorListenerImpl = new AjaxBehaviorListenerImpl(expression, expression);
	ajaxBehavior.addAjaxBehaviorListener(ajaxBehaviorListenerImpl);
	ajaxBehavior.setListener(expression);
	ajaxBehavior.setUpdate("@this");
	
	input.addClientBehavior("keyup", ajaxBehavior);[/code]

#2

Consegui corrigir parcialmente …

Minha classe FiltroPadrao possui um extends de PanelGrid, e passei como parâmetro no construtor um enum … dai dava zica … foi retirar o parâmetro passou a mudar o erro :smiley:
Agora me surgiu outro erro … que também não faço ideia do porque o erro é o seguinte …

#3

Consegui resolver …

Nessa parte do código estava passando o parametro classe errada :S foi somente colocar a classe como vazia ela passou a funcionar <3

public static MethodExpression criarMethodExspression(String valor, Class classe) { ExpressionFactory factory = FacesContext.getCurrentInstance() .getApplication().getExpressionFactory(); ELContext elContext = FacesContext.getCurrentInstance().getELContext(); return factory.createMethodExpression(elContext, valor, void.class, new Class<?>[] { classe }); }
