TransientObjectException in seamspace-like approach
Hi, I try to use a User/UserRole relation and took the seam-space as example
I have a UserRole entity with some predefined rolenames in database
UserRole class:
@Entity
@Name("userroles")
public class UserRole implements Serializable {
/**
*
*/
private static final long serialVersionUID = -8632996340533021763L;
private Long id;
private Integer version;
private String name;
@Id @GeneratedValue
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
@Version
public Integer getVersion() {
return version;
}
@SuppressWarnings("unused")
private void setVersion(Integer version) {
this.version = version;
}
@Length(max=20)
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}and a User class as counterpart
@Entity
@Name("user")
@Table(name = "user", catalog = "oats")
public class User implements java.io.Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
private long id;
private Long version;
private String userName;
private String email;
private Set<UserRole> userRoles;
public User() {
}
public User(long id) {
this.id = id;
}
@Id @GeneratedValue
public long getId() {
return this.id;
}
public void setId(long id) {
this.id = id;
}
@Column(name = "version")
public Long getVersion() {
return this.version;
}
public void setVersion(Long version) {
this.version = version;
}
@Column(name = "username", unique = true)
@NotEmpty
public String getUserName() {
return this.userName;
}
public void setUserName(String username) {
this.userName = username;
}
@Column(name = "email")
@Email(message="Email")
@NotEmpty
public String getEmail() {
return this.email;
}
public void setEmail(String email) {
this.email = email;
}
@ManyToMany
@JoinTable(name = "userroles", joinColumns = @JoinColumn(name = "USER_ID"), inverseJoinColumns = @JoinColumn(name = "ROLE_ID"))
public Set<UserRole> getUserRoles() {
return userRoles;
}
public void setUserRoles(Set<UserRole> userroles) {
this.userRoles = userroles;
}
}Than I have a wizard(with a4j:include) to create new users with the predefined userroles.
(user data are based on existing values from database)
first step:
<div class="navPanel">
<h:outputLabel for="gpid" value="GP-Id"></h:outputLabel>
<h:inputText id="gpid" value="#{user.userName}"></h:inputText>
<a4j:commandButton value="Next >>" action="#{register.searchGpId}"/>
</div>@Begin
public String searchGpId() {
String query = "from Csy20oats y20 where y20gpnum like '" +user.getUserName() +"'";
userSearchResults = entitymanager.createQuery(query).getResultList();
return "next";
}these results are displayed in a datatable and one record can be used to select user data
<div class="navPanel">
<rich:scrollableDataTable
rows="10"
id="userresultdatatable"
var="data"
value="#{register.userSearchResults}">
<rich:column width="50px">
<f:facet name="header"><h:outputText value="GP-Id"></h:outputText></f:facet>
<h:outputText value="#{data.y20gpnum}"></h:outputText>
</rich:column>
<rich:column width="150px">
<f:facet name="header"><h:outputText value="Name"></h:outputText></f:facet>
<h:outputText value="#{data.y21kname}"></h:outputText>
</rich:column>
<rich:column width="75px">
<f:facet name="header"><h:outputText value="Aktion"></h:outputText></f:facet>
<a:commandLink id="userselectlink" action="#{register.selectUser(data)}" value="Ausweahlen"></a:commandLink>
</rich:column>
</rich:scrollableDataTable>
</div>
public String selectUser(Csy20oats selectedUser) {
setAllFields(selectedUser);
return "next";
}
@SuppressWarnings("unchecked")
private void setAllFields(Csy20oats selectedUser) {
List<Csy20oats> rs = entitymanager.createQuery("from Csy20oats y20 where y20.y20gpnum=" +selectedUser.getY20gpnum()).getResultList();
userroles = new HashSet<UserRole>();
for(Csy20oats y20 : rs){
if(y20.getY20y20s0().substring(0, 1).toLowerCase().equals("k")){
UserRole ur = (UserRole)entitymanager.createQuery("from UserRole ur where ur.name = 'akzeptanz'").getSingleResult();
//this.user.getUserRoles().add(ur);
userroles.add(ur);
}else if(y20.getY20y20s0().substring(0, 1).toLowerCase().equals("d")){
UserRole ur = (UserRole)entitymanager.createQuery("from UserRole ur where ur.name = 'beherbergung'").getSingleResult();
//this.user.getUserRoles().add(ur);
userroles.add(ur);
}else if(y20.getY20y20s0().substring(0, 1).toLowerCase().equals("s")){
UserRole ur = (UserRole)entitymanager.createQuery("from UserRole ur where ur.name = 'gemeinde'").getSingleResult();
//this.user.getUserRoles().add(ur);
userroles.add(ur);
}
}
}
in last step I can edit and save the data
<div class="navPanel">
<h:outputLabel value="Name" for="username"></h:outputLabel>
<h:inputText id="username" value="#{user.userName}"></h:inputText>
<br/>
<h:outputLabel value="E-Mail" for="email"></h:outputLabel>
<h:inputText id="email" value="#{user.email}"></h:inputText>
<br/>
<rich:spacer height="2" id="userspacer"></rich:spacer>
<rich:separator lineType="dashed"></rich:separator>
<a:commandButton value="Registrieren" action="#{register.register}"/>
</div>
@End
public String register()
{
this.user.setUserRoles(userroles);
try {
entitymanager.persist(this.user);
} catch (Exception e) {
e.printStackTrace();
}
return "next";
}
I think it's exact the same as in seamspace but I get the following error:

If I use ManyToMany(cascade=CascadeType.PERSIST) there is no error but new UserRole entries are created(I don' want new roles)
What's diffrent in seam-space example OR better, what can I do prevent this error?
