private SkillType skillType;
private Double experienceTime;
}
SkillType.java
public class SkillType{

return null;
}
try {
System.out.println("convert skill");
Long id=Long.parseLong(value);
return new Skill(id);
} catch (Exception e) {
throw new ConversionError(MessageFormat.format("Erro ao converter Distrito", value));
}
}
}

Estou invocando da seguinte forma
<label for="district">Selecione o bairro: </label>
<select id="district" name="user.district" disabled="disabled">
</select>
<label for="skills">Selecione uma habilidade: </label>
<select id="skills" name="user.skills[0].skillType.id">
#foreach($item in $skills)
<option value="$item.id">$item.name</option>
#end
</select>
<label for="user.skills[0].skillLevel">
Como voce se avalia nessa habilidade?<br>
<input type="radio" name="user.skills[0].skillLevel" value="BEGINNER"> <span>Iniciante</span> <input type="radio" name="user.skills[0].skillLevel" value="BASIC"> <span>Basico</span> <input type="radio" name="user.skills[0].skillLevel" value="ADVANCED"> <span>Avançado</span> <input type="radio" name="user.skills[0].skillLevel" value="PROFESSIONAL"> <span>Profissional</span>
</label>
No final ele cria um objeto user porém so passa pelo DistrictConverter…ele nao passa pelo SkillTypeConverter e nen pelo SkillConverter e cria objetos java normais, não entendi isso por que criei os 3 converters da mesma forma por que apenas 1 deles funciona?
se alguém puder ajudar agradeço.
