Outjection of previous value: selectOneMenu : One 2 Many Rel
JBoss 4.0.4.GA
JBoss Seam 1.0.1 GA
Hi, I am really stuck and cant progress :-(
I have a page called viewRatePage, which allows
users to add Rate objects to their profile. When
I add a new rate, the selectOneMenu items never
clear on the refresh when a new rate is added,
it contains the old selection of the previous
rate. I do force a null on the injected rate, but
this has no effect. Please please can anyone help?
This issue affects other pages which have the same
relationship, ie adding items to a list.
These are my previous posts:

This is my view:

Any my Rate object that gets instantiated is an entity bean:
@Entity
@Name("rate")
@Scope(EVENT)
public class Rate implements Serializable {
protected int Id = 0;
protected int duration = 0;
protected String unit = null;
protected String currency = null;
protected int cost = 0;
protected RatesPage ratesPage = null;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
public int getId() {
return Id;
}
public void setId(int id) {
Id = id;
}
... // for brevity
My session bean behind the page is (with unnecessary methods removed):
@Stateful
@Scope(ScopeType.SESSION)
@Name("ratesPageManager")
@Interceptors(SeamInterceptor.class)
@LoggedIn
@TransactionAttribute(REQUIRES_NEW)
public class RatesPageManagerBean implements RatesPageManager {

Upon inserting the first rate, the view still shows the previous rate in the selectMenus, if you
change it and reinsert, the following exception is thrown

The server debug log shows that the previous rate object is passed down.
I tried modifiying the messages example with no success as the input field in the view
still had the old inserted value, see previous thread i mentioned.
Any ideas people ... i tried formatting this properly to get some help about this :-(
