I have a page that should display a list of most recent events ocured. By
clicking on each event some information should be displayed about the event.
I am using a DataModel to display the list, but the problem is that after
clicking an item, the DataModelSelection is null.
I have made a simplified example, in order to show the problem:
| @Name("eventComponent")
| @Scope(ScopeType.EVENT)
| public class MyLatestAction {
|
| @In FacesMessages facesMessages;
|
| @DataModel(value="eventList")
| private List<Integer> eventList;
|
| @DataModelSelection
| private Integer selectedEvent;
|
| @Factory("eventList")
| public void initRequestList() {
| eventList = new ArrayList<Integer>();
| eventList.add(1);
| eventList.add(2);
| eventList.add(3);
| }
| public void selectEvent() {
| facesMessages.add("selected event: "+selectedEvent);
| }
|
| }
|
the view eventList.xhtml contains this code:
| ...
| <h:messages globalOnly="true" styleClass="message"/>
|
| <h:dataTable value="#{eventList}" var="item" >
| <h:column>
| <f:facet name="header">Event</f:facet>
| <s:link action="#{eventComponent.selectEvent}"
value="#{item}"/>
| </h:column>
| </h:dataTable>
|
| ...
|
I am accessing the page from the menu with a link like this:
| <s:link view="/eventList.xhtml" value="Event List"/>
|
The problem is that even though the page correctly displays the list of events
(1, 2, 3), when I select an event, in the bean the selection is null (it prints
"selcted event: null"
What am I doing wrong
