[JBoss Seam] - Help, <s:convertEntity /> problem
by nicoliniyo
I was writting the code for and app to add a record to the database:
(I've translated the code from spanish, asume the code has no typo)
this is a form to add a currency, the currency has a country mapped to it.
The xhtml form uses a tempate with <s:vallidateAll>
Here the monedaNueva.xhtml:

|
| </h:selectOneMenu>
|
| </s:decorate>
| ...
And an error came out:
| Conversion Error setting value ....Country@qw12... 'null Converter'.
|
So I've added the <s:convertEntity /> under the <s:selectItems line:
| ...
| <s:decorate template="edit.xhtml">
| <ui:define name="label">
| <label jsfc="h:outputLabel" for="country" value="#{m['E_COUNTRY']}"></label>
| </ui:define>
|
| <h:selectOneMenu id="country" value="#{currency.country}">
| <s:selectItems value="#{countryList}" var="aCountry" label="#{aContry.name}" />
| <s:convertEntity />
| </h:selectOneMenu>
|
| </s:decorate>
| ...
After I've added the <s:convertEntity /> I try enter the xhtml page and the following error comes out:

[JBoss Seam] - Updating a many to many relationship from the inverse side
by rganogork
Hi.
I have been trying to update a many to many realationship from the inverse entity and i am getting a 'org.hibernate.LazyInitializationException: illegal access to loading collection'.
| @ManyToMany(mappedBy = "fleets", fetch = FetchType.EAGER)
| public List<User> getUsers() {
| return users;
| }
|
| public void setUsers(List<User> users) {
| // Add users to relation
| if (users != null) {
| for (User u : users) {
| u.getFleets().add(this);
| }
| }
|
| this.users = users;
| }
|
The offending line is u.getFleets().add(this). The user fleets seems to be lazy loaded (i specified EAGER loading on the User entity class) and the Hibernate session discarded.. However i don't know why would the hibernate session be discarded.
Doing the same with many to one and one to one relationships worked fine.
Also pointers on how else i could be doing this, or pointers to further documentation will be largely apreciated.
Thank you,
Adrian.
