I have an entity Person that has a ManyToMany relation to other Persons
("friends" ;)). When editing one person there's a SelectManyMenu showing all
Persons and you can select or deselect friends.
The SelectManyMenu has a Converter (... converter="#{personConverter}"), of
course. This one is implemented as a Stateless Session Bean with
@Name("personConverter") and the two methods getAsString(...) and
getAsObject(...).
The persons are filled into that List by <f:selectItems
value="#{personListe.selectItems}" />. You guess it, the selectItems() method
returns a List, which's items are all added like this: ...add(new
SelectItem(aPerson.getId(), aPerson.getName()));
So far so good. Should be nothing special here ;).
When going to the edit page everything works fine, and the Log shows me that
the getAsString-method is called for every Person in the list.
BUT: As soon as a safe the edited person (and it doesn't play a role whether I
select friends or not) there's an Exception:
FATAL [org.apache.myfaces.renderkit.html.HtmlRepsonseStateManager] Cannot
decode Object from Base64 String
| java.lang.ClassNotFoundException: No ClassLoaders found for:
de.beffo.test.converter.PersonConverter
| at org.jboss.mx.loading.LoadMgr3.beginLoadTask(LoadMgr3.java:212)
| at ...
Well... how can it be that the Converter is found when the page is displayed,
and not found right after submitting? Anyone having experience with such a
behaviour?
