Se eu tentar acessar o banco utilizando qualquer função DAO, acontece esse erro postado logo abaixo... , mas somente quando a chamada da action é pela função js . caso contrário tudo funciona perfeitamente.

... Debugando o problema acontece exatamente nesse ponto dentro da action :

List<Aplicacao> apps = aplicacaoDAO.findByList(aplicacao,"ordem");


alguém pode me dá uma mão ?????

Valeu

PS: me basei no F.A.Q do robert.

JSP
Code:
<script type="text/javascript">
 			function loadListBean(){
 				var r = new mtw.request();
 				r.setUrl("MenuAction.getListBean.mtw");
 				r.onSuccess(getListBean);
 				r.useLoadingMessage("Carregando Menu, Aguarde...");
 				r.send();
 			}
 			
 			function getListBean(trans){
 				var data = new mtw.response(trans);
 				var msg = "";
 				var menu;
 				for(var index=0; index<data.size(); index++) {
 					menu = data.getObject(index);
 					msg += menu.programa + "><br> <br>";
 					
 				}
 				document.getElementById("getListBeanDiv").innerHTML = msg;
 			}
 			</script>
 			<input type="button" value="LoadListBean" onclick="loadListBean();">
 			<input type="button" value="Limpar"
 				onclick="$('getListBeanDiv').innerHTML=''">
 			<div id="getListBeanDiv"></div>


AppMan
Code:
action(MenuAction.class, "getListBean").ajaxOk(new JSONGenericRenderer(1));


Action
Code:
   public String getListBean() {
        
                 Aplicacao aplicacao = new Aplicacao();
                 aplicacao.setUsuario((String) getUserSession());
                 aplicacao.setMenu(12);
                 
                 List<Aplicacao> apps = aplicacaoDAO.findByList(aplicacao,"ordem");
                 
                 
 		output.setValue(AjaxConsequence.KEY, apps);
 		return SUCCESS;
   }

seu browser etc...

Code:
  
         action(MenuAction.class, "getListBean").ajaxOk(new JSONGenericRenderer(1))
         .filter(common);

Embora esta thread pareça terminada, pegando um gancho com o escopo, o que faz o filtro common, no final da definição da action em .filter(common)? Obrigado

é isso mesmo robert .... flavio eu uso Hibernate com Annotation ai no meu AppManager fica assim juntamente com o restante dos filtros comuns.

Code:
  List<Filter> common = new ArrayList<Filter>();
          
         common.add(new ValidatorFilter());
         common.add(new ConverterFilter());
         common.add(new IoCFilter(aplicacaoDAO, "aplicacaoDAO", REQUEST));        
         common.add(new IoCFilter(usuarioDAO, "usuarioDAO", REQUEST));
         common.add(new IoCFilter(tituloMenuDAO, "tituloMenuDAO", REQUEST));           
         common.add(new IoCFilter(menuDAO, "menuDAO", REQUEST));   
         common.add(new IoCFilter(filialDAO,"filialDAO",REQUEST));
         common.add(new IoCFilter(fornecedorDAO,"fornecedorDAO",REQUEST));        
         common.add(new IoCFilter(produtoDAO,"produtoDAO",REQUEST));        
         common.add(new IoCFilter(clienteDAO,"clienteDAO",REQUEST));                
         common.add(new IoCFilter(vendedorDAO,"vendedorDAO",REQUEST));                        
         common.add(new HibernateFilter(sessionFactory));
         common.add(new DIFilter());
         common.add(new InjectionFilter());
