Hi,
I just had a few hours of nice debugging time with the @SelectItems stuff.
This first one works ok:
anonymous wrote :
| <h:selectOneListbox value="#{selector.selectedRegion}">
| <f:selectItems value="#{regions}"/>
| </h:selectOneListbox>
but this doesn't
anonymous wrote : <h:selectOneListbox value="#{region}">
| <f:selectItems value="#{selector.regions}"/>
| </h:selectOneListbox>
"selector" is SFSB with get/setRegions, get/setSelectedRegion in local
interface and
@SelectItems
| public List getRegions() {
| List<Region> regions = (List<Region>) em
| .createQuery("from Region").getResultList();
| return regions;
| }
|
Instead the second one gives the following exception:
| 2006-09-19 15:14:57,367 ERROR

So instead of the wrapped result the original List (of Regions) is passed to
f:selectItems.
Is this expected behaviour?
