Hello,

I use RichFaces 3.2.1_GA and i have a problem with the rich:scrollableDataTable, and the selection of row.

When I start my applicaction, the scrollableDataTable is displayed correctly.
When I select a row into scrollableDataTable an display this selection in the dataTable to a modalPanel, the dataTable is empty.

I'm start since the demo http://livedemo.exadel.com/richfaces-demo/richfaces/scrollableDataTable.jsf?c=scrollableDataTable

My xHtml code :

</rich:dataTable>
</rich:modalPanel>
</ui:define>
</ui:composition>

and my java code :


package fr.horoquartz.geveseam.bean;

@Stateful
@Name("personBean")
@JndiName("Geve/PersonBean/remote")
@Scope(ScopeType.CONVERSATION)
public class PersonBean implements Serializable, PersonRemote {
private static final long serialVersionUID = 1L;


@DataModel
private List personsList = null;
private SimpleSelection selection = new SimpleSelection();
private UIScrollableDataTable table = null;
private ArrayList selectedPersons = new ArrayList();

@DataModelSelection("personsList")
@Out(required=false)
private Person person;

public List getPersonsList() {
return personsList;
}

public void setPersonsList(List personsList) {
this.personsList = personsList;
}

public Person getPerson() {
return person;
}

public void setPerson(Person person) {
this.person = person;
}

public SimpleSelection getSelection() {
return selection;
}

public void setSelection(SimpleSelection selection) {
this.selection = selection;
}

public UIScrollableDataTable getTable() {
return table;
}

public void setTable(UIScrollableDataTable table) {
this.table = table;
}

public ArrayList getSelectedPersons() {
return selectedPersons;
}

public void setSelectedPersons(ArrayList selectedPersons) {
this.selectedPersons = selectedPersons;
}

@SuppressWarnings("unchecked")
@Factory("personsList")
public void findPersons()
{
// logger.info("findPersons");
// TODO : getAllPerson();
// personsList = getAllResidants();
personsList = em.createQuery("select person from Person person order by person.id desc").getResultList();
// messageList = em.createQuery("select msg from Message msg order by msg.datetimeMess desc").getResultList();
}

public String takeSelection() {
getSelectedPersons().clear();
System.out.println(getSelection().size());
if (getSelection().isSelectAll()) {
getSelectedPersons().addAll(personsList);
}
else {
Iterator iterator = getSelection().getKeys();
while (iterator.hasNext()) {
SimpleRowKey key = (SimpleRowKey) iterator.next();
table.setRowKey(key);
if (table.isRowAvailable()) {
getSelectedPersons().add((Person)table.getRowData());
}

}
}
return null;
}

@Remove @Destroy
public void destroy() {
System.out.println("personBean : destroy");
}
}


In the function takeSelection the getSelection().size() is always equal to 0.

Does anyone knows a solution on this?

thanks
