[Resolvido] VRaptor - Enum e BigDecimal ao criar DTO

Assuntos Gerais
#1

Estou com uma estrutura simples:

@Post("/account/new") public void insert(AccountDTO dto){

Onde o AccountDTO tem um construtor assim:

	public AccountDTO(String hash, String description, Icon icon, BigDecimal initialBalance,
			Portfolio portfolio, AccountType accountType) {

e tenho meus inputs…

									<input class="span6" type="text" name="dto.description">
											
									<select class="chzn-select" name="dto.icon">
										<c:forEach items="${icons}" var="icon">
								       		<option value="${icon}" class="${icon.cssClass}" >${i18n[icon.label]}</option>
										</c:forEach>								
									</select>

									<select name="dto.accountType" class="chzn-select">
										<c:forEach items="${accountTypes}" var="type">
											<option value="${type}">${i18n[type.label]}</option>
										</c:forEach>
									</select>									

									<input class="span4" type="text"  name="dto.initialBalance">									

								<input type="hidden" name="dto.portfolio">							
								<input type="hidden" name="dto.hash">

ai explode uma exception no console:

Ideias ?

**EDIT

tirei o Icon do construtor e do request, ai deu um erro reclamando do BigDecimal, um erro bem parecido, mas já dei clean no console e perdi
a exception… Mas uma coisa de cada vez né ? haahah
O que será que estou fazendo de errado?

#2

Icon é uma enum mesmo?

#3

Lucas, é sim:

public enum Icon implements Translatable {
	GLASS, LEAF, DOG, USER, GIRL, CAR; //mais uns trocentos
      
	public String getCssClass() {
		return "icon-" + name().toLowerCase().replace("_", "-");
	}

	@Override
	public String getLabel() {
		return "icon." + name().toLowerCase().replace("_", ".");
	}

EDIT

Será que tem algo com o IOGI ?
Versão: 0.9.2

versão do VRatpr 3.5.1

Estou usando o gradle…
e tenho apenas:

	compile library.vraptor

num arquivo eu seto no libarry:

ext.library['vraptor'] = "br.com.caelum:vraptor:3.5.1"

Obrigado

#4

Tenta tirar o implements Translatable… em todo caso é bem estranho…

qual é o erro que dá qdo vc tira ele do construtor?

#5

Aí da erro no BigDecimal:

[code]1) Could not find a suitable constructor in java.math.BigDecimal. Classes must have either one (and only one) constructor annotated with @Inject or a zero-argument constructor that is not private.
at java.math.BigDecimal.class(Unknown Source)

[/code]

Aí, fazendo o teste sem o BigDecimal, da erro no Outro enum AccountType

[code]1) No implementation for com.m.model.enums.AccountType was bound.
while locating com.m.model.enums.AccountType

[/code]

Onde:

public enum AccountType implements Translatable {
	
	CHECKING, SAVINGS, INVESTMENT;

	@Override
	public String getLabel() {
		return "account.type." + name().toLowerCase();
	}

Tirando esse Enum da requisição,
temos: SUCESS! x]

Ou seja, sem Enum e sem BigDecimal funciona… Mas aí meu construtor final ficou peladin peladin oia só:

public SaveableAccount(String hash, String description, Portfolio portfolio) {

Duas Strings e um Portfolio (no qual possuo um converter).

Complica né ?

Com certeza deve ter alguma coisa de errado né Lucas?
Não faz sentido :frowning:

vou tirar o translateble dos enums e vou tentar de novo e já posto o resultado

EDIT

Da o mesmo erro :frowning:

#6

populando via setter funciona tranquilo?

#7

Cara, eu removi o construtor e coloquei os setters…
e funcionou… *Alias, deu erro, mas de persistencia… sinal que funcionou! kkkkkkkk

Aí eu deixei o construtor + os setters…e deu o mesmo erro no Enum…
Estranho isso!!

cara o engraçado é que tem outros lugares que uso objetos imutaveis, sem contar que sem o bigdecimal e os enums, funcionou…

tem alguma ideia?

#8

Parece um bug no IOGI… só pra confirmar: se vc deixar um construtor sem o bigdecimal e os enums e setters pra eles dá o erro do enum, certo?

#9

Cara, deu erro de persistência, mas veja só::

O que implica que o accountType esta null…

bom, debugando…

cara, não setou nada!
apenas o Portfolio !!

EDIT

Opa, nem o Portfolio setou…
foi uma instancia default do portfolio…
¬¬

tem boi na linha no meu post!

#10

ele chega a dar algum erro de conversão? antes de mandar pra salvar no banco de dados checa o validator.getErrors() e veja se ele tá vazio.

#11

AAAAAAAAARG…

O problema era o POST… tava fazendo burrice e o form não estava sendo serializado!!
Esta funcionando perfeitamente o IOGI…

Mas é foda… a msg de erro me fez pensar em TUDO, menos olhar o request!
afffffff
burrice minha também…

obrigado Lucas,
desculpa cara =[

#12

sem problemas… mas pra dar esse erro alguma coisa foi pro request… bem estranho.
