Popular select multi-valorado usando Vraptor 3

Rodrigo_Pereira_Vale · Junho 22, 2010, 10:01pm

Olá pessoal,

Estou escrevendo um sistema onde tenho um controller do VRaptor que possui uma lista de UserAccount. Essa lista contém todos os UserAccounts
de um sistema e preciso exibi-lá em select multi-valorado para que o usuário sejá capaz de associar os UserAccounts com o cadastro de um documento.

A parte que estou encontrando dificuldade é em criar a tag SELECT no meu jsp de modo que o Vraptor à popule para mim com os valores da lista supracitada.

Esse é o meu arquivo jsp:

&lt;!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"&gt;
&lt;%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %&gt;
&lt;%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %&gt;
&lt;html&gt;
	&lt;head&gt;
		&lt;title&gt;Release Notes System &lt;/title&gt;
         ...	
	&lt;/head&gt;

        &lt;body&gt;

	&lt;div id="container"&gt;
		
                  &lt;jsp:include page="../common/menu.jsp"&gt;&lt;/jsp:include&gt;
			
	          &lt;div id="content"&gt;
       
                  &lt;form action="&lt;c:url value='/releaseDocument/addReleaseDocument'/&gt;" method="post"&gt;
			
    		   &lt;table&gt;
    				
    			  &lt;tr&gt;
    				   &lt;td valign="top"  width="200"&gt;
                                               Developers
                                   &lt;/td&gt;
    				   &lt;td&gt;
    				               &lt;select name="releaseDocument.listUserAcount" id="releaseDocument.listUserAcount" multiple="multiple"&gt;  
                                                      &lt;c:forEach var="userAccount" items="${listUserAcount}"&gt;  
                                                            &lt;option value="${userAccount.idUserAccount}" ${selected}&gt;${userAccount.name}&lt;/option&gt;  
                                                      &lt;/c:forEach&gt;  
                                              &lt;/select&gt;   
    				   &lt;/td&gt;
    			   &lt;/tr&gt;
    		
    		    &lt;/table&gt;
    				
	            &lt;/form&gt;   
	&lt;/div&gt;
&lt;/div&gt;
&lt;/body&gt;
&lt;/html&gt;

E aqui está o código do meu controller:

@Resource
public class ReleaseDocumentController {

	private final Logger logger = Logger.getLogger(ReleaseDocumentController.class);
	private final UserAccountDao userAccountDao;
	private Result result;
	
	[b]private List&lt;UserAccount&gt; listUserAccount;[/b] //essa é a lista que deve ser exibida na view
	
	public ReleaseDocumentController(DaoFactory daoFactory, Result result) {
		this.userAccountDao = daoFactory.getUserAccountDao();
		this.result = result;
	}

	public List&lt;ReleaseDocument&gt; listReleaseDocument() {
		List&lt;ReleaseDocument&gt; list = releaseDocumentDao.findAll();
		return list;
	}
	
	public void formAdd(){
		[b]this.listUserAccount = userAccountDao.findAll(); [/b]  //nesse ponto eu populo a lista e o formAdd.jsp é chamado
		logger.trace(&quot;Invoked Method -&gt; ReleaseDocumentController::formAdd&quot;);
	}
	
	public void addReleaseDocument(Strint[] listUserAcount){
                //nesse ponto eu deveria receber a lista com os UsserAccts que o usuário selecionou no formulário
		releaseDocumentDao.save(releaseDocument);
	}

	public List&lt;UserAccount&gt; getListUserAccount() {
		return listUserAccount;
	}

	public void setListUserAccount(List&lt;UserAccount&gt; listUserAccount) {
		this.listUserAccount = listUserAccount;
	}

}

Vejam que na tag <select name=“listUserAccount” id=“listUserAccount” multiple=“multiple”> eu utilizei o mesmo
nome da lista da minha action.

Alguem saberia me informar se estou no caminho certo?

baixe o último snapshot do vraptor:
http://oss.sonatype.org/content/repositories/snapshots/br/com/caelum/vraptor/3.1.3-SNAPSHOT/vraptor-3.1.3-20100607.234700-8.jar

e use como nome do select:

listUserAccount[].id

vc pode dar qqer outro nome pra essa lista, não precisa ser listUserAccount, vc só tem que usar o mesmo nome no select e no parametro do método

Rodrigo_Pereira_Vale · Junho 23, 2010, 9:05am

Olá Lucas! Obrigado pela dica.

Fiz como vc disse, baixei essa versão do VRaptor (3.1.3-20100607.234700-8.jar) substitui o o vraptor3.1.2.jar que eu estava usando por ele e tambem mude o nome e ID do select como
voc citou, porem, ainda estou recebendo uma lista em branco.

Aqui está o html gerado

&lt;select name="listUserAccount[].id" id="listUserAccount[].id" multiple="multiple"&gt;  
&lt;/select&gt;

Será que a minha lista está sendo disponibilizada corretamente no controller? No Struts2 eu uso o método prepare() da interface Preparable para carregar as minhas listas antes da minha página ser renderizada, porem, no VRaptor não sei se existe algo parecido.

Será que esse é o problema?

Lucas_Cavalcanti · Junho 23, 2010, 10:33am

o VRaptor não popula os parametros por setters!

vc recebe o parâmetro direto no método da lógica mesmo:

public void minhaLogica(List<UserAccount> listUserAccount) {
   ...
}

Rodrigo_Pereira_Vale · Junho 23, 2010, 10:41am

Sim Lucas, mas o problema aqui é o inverso. Eu tenho a lista populada no meu controller. Porem os dados dessa lista não estão aparecendo no meu JSP.

O metodo que eu chamo e que direciona para o formulario onde eu preciso exibir a lista é esse:

public  void formAdd(){  
         this.listUserAccount = userAccountDao.findAll(); //nesse ponto eu populo a lista e o formAdd.jsp é chamado  
         logger.trace(&quot;Invoked Method -&gt; ReleaseDocumentController::formAdd&quot;);  
}

seria o caso se eu adicionar a seguinte modificação?

public  void formAdd(List&lt;UserAccount&gt; listUserAccount){  
         listUserAccount = userAccountDao.findAll(); //nesse ponto eu populo a lista e o formAdd.jsp é chamado  
         logger.trace(&quot;Invoked Method -&gt; ReleaseDocumentController::formAdd&quot;);  
}

garcia-jj · Junho 23, 2010, 2:06pm

O vraptor exporta os objetos via result.include ou via retorno do método; ao contrário do struts2 que exporta via atributos com setters.

public void formAdd(){ result.include("listUserAccount", userAccountDao.findAll()); //nesse ponto eu populo a lista e o formAdd.jsp é chamado logger.trace("Invoked Method -> ReleaseDocumentController::formAdd"); }

Rodrigo_Pereira_Vale · Junho 23, 2010, 4:40pm

Funcionou perfeitamente Pbragado pela ajuda pessoal!

Rodrigo_Pereira_Vale · Junho 28, 2010, 10:35pm

Pessoal, descobri um outro problema aqui.

Já vi ele em outra thread aqui porem oq foi dito lá não resolveu meu problema então vou postar aqui.

Como visto nas mensagens acima, eu consegui exibir os dados do meu controller para o meu JSP. Só que agora preciso do inverso. Baseado nos IDs que o usuário

marcar no SELECT multiple do meu JSP eu preciso que o VRaptor injete no meu metodo uma lista com os IDs selecionados, ou mesmo se possível os objetos UserAcct instanciados… isso seria possivel com o VRaptor?

Aqui está o meu JSP:

&lt;select name="developersList[].id" id="developersList[].id" multiple="multiple" style="width: 300px"&gt;  
                                 &lt;c:forEach var="userAccount" items="${listDevelopers}"&gt;  
                                     &lt;option value="${userAccount.idUserAccount}"&gt;${userAccount.name}&lt;/option&gt;  
                                 &lt;/c:forEach&gt;  
                       &lt;/select&gt;

Arqui está o metodo do controller:


public void addReleaseDocument(ReleaseDocument releaseDocument, List&lt;String&gt; developersList){
		logger.trace("Developers: " + developersList.size());
		...
	}

Estou usando essa versão do VR http://oss.sonatype.org/content/repositories/snaps...or-3.1.3-20100607.234700-8.jar

alguma pista?

Lucas_Cavalcanti · Junho 28, 2010, 10:48pm

só receber uma List chamada developersList no método (vc pode chamar do q vc quiser, de qqer forma)

Rodrigo_Pereira_Vale · Junho 28, 2010, 10:54pm

Mesmo o meu UserAccount.java não sendo anotado como @Component?

Lucas_Cavalcanti · Junho 28, 2010, 10:56pm

sim =)

o @Component é só pra dependências… que vc recebe no construtor das classes e que precisam ser gerenciados pelo VRaptor…

para parâmetros de lógicas pode ser qqer classe… (desde que tenha um construtor padrão ou um converter)

Rodrigo_Pereira_Vale · Junho 28, 2010, 11:13pm

Não funcionou Lucas.

o html gerado pelas taglibs ficou assim:

&lt;tr&gt;
    				   &lt;td valign="top"  width="200"&gt;Developers&lt;/td&gt;
    				   &lt;td&gt;
    				   
    				   &lt;select name="developersList[].id" id="developersList[].id" multiple="multiple" style="width: 300px"&gt;  
                                   
                                     &lt;option value="2         "&gt;2                                                 &lt;/option&gt;  
                                   
                                     &lt;option value="1         "&gt;1                                                 &lt;/option&gt;  
                                   
                       &lt;/select&gt;

porem vejo essa exception nos logs do VRaptor:

Será que é por causa do especo colocado junto do Value no SELECT?

Lucas_Cavalcanti · Junho 28, 2010, 11:25pm

vc tem certeza que tá com o último snapshot do VRaptor?

vc tirou a versão antiga? o vraptor-3.1.2.jar não pode estar no WEB-INF/lib, só aquele jar do link q vc falou

Rodrigo_Pereira_Vale · Junho 29, 2010, 12:00am

realmente estava com outra lib do VRaptor. Agora deixei somente a do link (veja lista abaixo) porem estou pegando uma exception ao iniciar a aplicação:

Acredito estar faltando algum jar?

Lucas_Cavalcanti · Junho 29, 2010, 12:07am

substitua o paranamer-1.5.jar por esse:

http://github.com/caelum/vraptor/blob/master/vraptor-core/lib/mandatory/paranamer-2.2.jar

Rodrigo_Pereira_Vale · Junho 29, 2010, 11:41pm

Lucas,

Substitui o jar e deu certo. O problema é que ele tenta criar um objeto UserAccount novo então seria mais interessante eu receber um List<String> com os ids que o usuário escolheu, assim eu posso buscar os users no banco. Infelizmente ao mudar a assinatura do meu método de

   1. public void  addReleaseDocument(ReleaseDocument releaseDocument, List&lt;UserAccount&gt; developersList){  
   2.         logger.trace("Developers: " + developersList.size());  
   3.         ...  
   4.     }

para

   1. public void  addReleaseDocument(ReleaseDocument releaseDocument, List&lt;String&gt; developersList){  
   2.         logger.trace("Developers: " + developersList.size());  
   3.         ...  
   4.     }

eu estou recebendo essa exception aqui

Meu JSP continua o mesmo… será que devo alterar algo lá?

Lucas_Cavalcanti · Junho 30, 2010, 12:40am

se vc vai receber List, vc não pode navegar pelas propriedades…

developersList[].id, ele tenta popular o id do objeto que tah na lista developersList… como a lista é de String, e String não tem id, ele dá esse erro…

vc pode usar só developersList[] como nome do seu select…

no hibernate tem uma operação chamada refresh, que se a entidade estiver com o id preenchido ele puxa do banco e preenche as outras propriedades:

session.refresh(userAccount);
