I generated a form:
<form:form action="${contextPath}/draw/constraints.do" method="post" modelAttribute="order"> <c:forEach items="${order.myDrawsAsArray}" var="draw" varStatus="status">
<label class="radio-inline"><form:radiobutton path="myDrawsAsArray[${status.index}].readable" value="true" /> yes</label>
<label class="radio-inline"><form:radiobutton path="myDrawsAsArray[${status.index}].readable" value="false" /> no</label>
</c:forEach></form:form>
When I submit it to update my entities, I got the following exception:
org.springframework.web.util.NestedServletException: Request

My controller is like this:
#Controller

public String constraints(
#ModelAttribute Order3d order,
#RequestParam("order") int id,

if(save!=null) {

}
Order3d o=(Order3d)s.createCriteria(Order3d.class).add(Restrictions.eq("id", id)).uniqueResult();
m.addAttribute("order", o);
s.close();
return "3dconstraints";
}
}
I also post my entities if you need them:
#Entity
#Table (name="order3d")
public class Order3d implements Serializable {
private static final long serialVersionUID = -2241346447352903470L;
public enum State {DEMAND, ESTIMATED, PAYED, PENDING, PRODUCED, SENT, DELIVERED};
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
#Column (name="id")
private int id;
#OneToMany(mappedBy="order3d", fetch = FetchType.EAGER, cascade=CascadeType.ALL)
private Set<DrawFile> myDraws;
public Set<DrawFile> getMyDraws() {
return myDraws;
}
public List<DrawFile> getMyDrawsAsList() {
return new ArrayList<DrawFile>(myDraws);
}
public Object[] getMyDrawsAsArray() {
return myDraws.toArray(); //line 121
}
//other getters & setters
public Order3d() {}
}
#Entity
#Table (name="draw", uniqueConstraints=#UniqueConstraint(columnNames="hashname"))
public class DrawFile implements Serializable {
private static final long serialVersionUID = -9024754876558087847L;
#Id
#GeneratedValue(strategy=GenerationType.AUTO)

private int id;
#Column (name="hashname", columnDefinition="CHAR(64)")
private String hashname;
#Column (name="filename")
private String filename="";
#Column (name="readable", columnDefinition = "BIT", length = 1)
private Boolean readable;
//getters & setters
public DrawFile() {}
}
I searched on the web but I didn't find a solution. Any idea?
How about try adding getter/setter to the fields in both Order3d and DrawFile classes?
The getters and setters must match field name, if the field is
List<DrawFile> myDraws;
then the getter/setter must be: (it cannot be getMyDrawsAsList())
public List<DrawFile> getMyDraws() {
return myDraws;
}
public void setMyDraws(List<DrawFile> myDraws) {
this.myDraws = myDraws;
}

I am trying to learn Spring Framework on the go. During runtime I get following stacktrace:
Validation failed for object='title'. Error count: 1
org.springframework.validation.BindException:
org.springframework.validation.BeanPropertyBindingResult: 1 errors
Field error in object 'title' on field 'status': rejected value
[Received];
I noticed that the problem is in the status, which is formatted by enum, but I can't any error.
My class Controller:
#Controller
#RequestMapping("/titles")
public class registerTitleController {
#RequestMapping("/title")
public String new() {
return "RegisterTitle";
}
#Autowired
private Titles titles;
#RequestMapping(method=RequestMethod.POST)
public String saveIn(Title title) {
titles.save(title);
return "RegisterTitle";
}
}
My class entity
#Entity
public class Title {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long cod;
private String description;
#DateTimeFormat(pattern="dd/MM/yyyy")
#Temporal(TemporalType.DATE)
private Date dateV;
private BigDecimal val;
#Enumerated(value = EnumType.STRING)
private StatusTitle status;
//other accessor methods
My class enum
public enum StatusTitle {
PENDING("Pending"),
RECEIVED("Received");
private String description;
private StatusTitulo(String descricao){
this.description = description;
}
public String getDescription() {
return description;
}
}
My system work without the status of the attribute.
Can someone point out what is wrong? Your help will be much appreciated.
You probably are sending "Received", but you need to send "RECEIVED" string to properly convert to the ENUM by default.
My Json document in the Morphia DB looks like this -
{
"_id" : ObjectId("58fcdf7e"),
"status" : "ACTIVE",
"user" : {
"id" : NumberLong(228),
"email" : "testing#domian.com"
}
}
I have created a Java class for this collection which looks like this -
#Entity("member_offer")
public class MemberOffer {
#Id
private ObjectId objectId;
#Property("status")
private String status;
#Embedded("user")
private UserDetail user;
#Embedded
class UserDetail {
#Property("id")
public long memberId;
#Property("email")
public String email;
UserDetail() {
}
}
public ObjectId getObjectId() {
return objectId;
}
public void setObjectId(ObjectId objectId) {
this.objectId = objectId;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public UserDetail getUser() {
return user;
}
public void setUser(UserDetail user) {
this.user = user;
}
}
Now when I am trying to fetch the data I am getting this exception -
java.lang.RuntimeException:
org.mongodb.morphia.mapping.MappingException: No usable constructor
for vo.MemberSubscription$UserDetail
Caused by: org.mongodb.morphia.mapping.MappingException: No usable
constructor for vo.MemberSubscription$UserDetail
Caused by: org.mongodb.morphia.mapping.MappingException: No usable constructor for vo.MemberSubscription$UserDetail
Caused by: java.lang.NoSuchMethodException: vo.MemberSubscription$UserDetail.()
Any idea how I can resolve this issue? I want UserDetail to be nested class only, I know if I create it as an independent class this error can be resolved. But my question here is can something like this (having nested class) can be achieved in Morphia?
Also if there is some fundamental flaw in my design please educate me about it.
You should try to use public modifier for the constructor, also make UserDetail (inner class) is static.
I am trying to add HATEOAS links with Resource<>, while also filtering with #JsonView. However, I don't know how to add the links to nested objects.
In the project on on Github, I've expanded on this project (adding in the open pull request to make it work without nested resources), adding the "Character" entity which has a nested User.
When accessing the ~/characters/resource-filtered route, it is expected that the nested User "player" appear with the firstNm and bioDetails fields, and with Spring generated links to itself, but without the userId and lastNm fields.
I have the filtering working correctly, but I cannot find an example of nested resources which fits with the ResourceAssembler paradigm. It appears to be necessary to use a ResourceAssembler to make #JsonView work.
Any help reconciling these two concepts would be appreciated. If you can crack it entirely, consider sending me a pull request.

try to change in ManageBean staffUpdateMB removeAddress(); method:
addressInfoDao.remove(address);
by
addressInfoDao.remove(address.getAddressID());
in your DAO you have:
public void remove(Object id);
but you are passing an object, not ID
I have a problem with resolving entities during entity manager startup.
Now it falls with following error:

I can not understand why eclispeLink have a problem to resolve simple mapping an_div->div.
All suggestion will be appreciated, I already spent too much time working on it. I can not see the mapping problem :(
Kind regards
