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 :D

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 
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);

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 }); }
