Hi, I am outjecting a DataModel on PAGE scope, but DataModelSelection is
null(when I click on a h:datatable row). I don't understand why it doesn't work
- I am struggling with it for a couple of days now.
Here is a simple application that does just this:
| @Name("eventLister")
| @Scope(ScopeType.EVENT)
| public class EventListerAction implements Serializable {
|
| @In FacesMessages facesMessages;
|
| @DataModel(value="eventList", scope=ScopeType.PAGE)
| 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);
| }
|
| }
|
and the page eventList.xhtml:
| <!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
|
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>
| <ui:composition xmlns="http://www.w3.org/1999/xhtml";
| xmlns:s="http://jboss.com/products/seam/taglib";
| xmlns:ui="http://java.sun.com/jsf/facelets";
| xmlns:f="http://java.sun.com/jsf/core";
| xmlns:h="http://java.sun.com/jsf/html";
| xmlns:a="https://ajax4jsf.dev.java.net/ajax";
| template="layout/template.xhtml">
|
| <ui:define name="body">
|
| <h:messages globalOnly="true" styleClass="message"/>
|
| <h:dataTable value="#{eventList}" var="item" >
| <h:column>
| <f:facet name="header">Event</f:facet>
| <s:link
action="#{eventLister.selectEvent}" value="#{item}"/>
| </h:column>
| </h:dataTable>
| </ui:define>
|
| </ui:composition>
|
Please help.
