Hi guys!
I 'm just starting to learn how to develop using jboss seams & facelets ejb3
and i ran into some problems, so im posting here if somebody can help this
little girl
If I have a list of objects "CaroTypeGroup" as I describe here, (this is when
u check the object with the eclipse inspector)
- groups=ArrayList
- elementData=Object[10]
- CAROTypeGroup
+ code="NAME001"
+ subTypes=PersistenceSet(id 602)
+ description="description 1"
+ id="id001"
- CAROTypeGroup
+ code="NAME002"
+ subTypes=PersistenceSet(id 603)
+ description="description 2"
+ id="id002"
... etc
Well this is my ejb Bean
| @Stateful
| @Name("caroGroups")
| @Scope(ScopeType.CONVERSATION)
| @Interceptor(SeamInterceptor.class)
| public class CaroTypeGroupListAction implements Serializable,
| CaroTypeGroupList {
|
| @PersistenceContext
| private Session session;
|
| @DataModel
| private List<CaroTypeGroup> groups;
|
| @DataModelSelectionIndex
| private int groupsIndex;
|
| @DataModelSelection
| private CaroTypeGroup selectedGroup;
|
| @Out(required = false)
| private CaroTypeGroup group;
|
| public String findCaroGroups() {
| groups = session.createCriteria(CaroTypeGroup.class).list();
| return "success";
| }
|
| @Begin
| public String setCaroGroup() {
| group = selectedGroup;
| return "success";
| }
|
----
As a Starting point, I just want to print that list (groups) to a page with a
data table that contains the following code:
| <h:dataTable value="#{groups}" var="g">
|
| <h:column>
| <f:facet name="header">Code</f:facet>
| #{g.code}
| </h:column>
|
| <h:column>
| <f:facet name="header">Actions</f:facet>
| <h:commandButton value="See"
action="#{caroGroups.setCaroGroup}" />
| </h:column>
|
| </h:dataTable>
|
The problem is that it doesn't print anything, like the atribute code is
empty, so I dunno if im using seam datamodel in the correct way or... what
could be my problem here? what am i doing wrong?..
Thanks
