ExtendedDataTable selection null in ui:include page
Greetings Everyone.
Im facing a problem with extendeddatatable and I will try to explain, I'm sorry if my english is not so good, maybe Im doing something wrong because Im pretty new in Richfaces and I spent some hours searching how to fix my problem but didnt found a solution.
Im using Richfaces 4.3.7 (I tried with 4.5.0 but still have the problem) and Mojara 2.2.0 with Hibernate (MySql Db) and Tomcat 8.0
I have a Homepage (.xhtml) with on the left commands and on right a ui:include inside a a4j outputpanel with src pointing to a backing bean proprierties, follow the portion of code of the ui:include.
<a4j:outputPanel ajaxRendered="true" id="targetArea" layout="block">
<ui:include src="#{homeBean.centralPage}" />
</a4j:outputPanel>
This is the page included:
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:a4j="http://richfaces.org/a4j"
xmlns:rich="http://richfaces.org/rich">
<html>
<rich:extendedDataTable value="#{ordiniBean.documenti}"
var="docum"
id="table_docs"
rows="60"
selection="#{ordiniBean.selection}"
selectionMode="single"
style="height:#{sessionParameters.tableHeight1}px;width:692px">
<a4j:ajax event="selectionchange" listener="#{ordiniBean.selectionListener}" />
<rich:column width="90px">
<f:facet name="header">
<h:outputText value="Data" />
</f:facet>
<h:outputText value="#{docum.docData}">
<f:convertDateTime type="date" pattern="dd/MM/yyyy" />
</h:outputText>
</rich:column>
</rich:extendedDataTable>
</html>
</ui:composition>
The extendeddatatable has a selection and a a4j:ajax event="selectionchange" that point at a listener in the backingbean:
private Collection<Object> selection;
public Collection<Object> getSelection() {
return selection;
}
public void setSelection(Collection<Object> selection) {
this.selection = selection;
}
public void selectionListener(AjaxBehaviorEvent event) {
AbstractExtendedDataTable dataTable = (AbstractExtendedDataTable)event.getComponent();
Object originalKey = dataTable.getRowKey();
selectionItems.clear();
for (Object selectionKey : selection) {
dataTable.setRowKey(selectionKey);
if (dataTable.isRowAvailable()) {
selectionItems.add((DocPartite) dataTable.getRowData());
}
}
dataTable.setRowKey(originalKey);
}
The problem I have is that when the event its fired my variable "selection" its always null.
I think the problem its because the page its loaded in a ui:include because if I launch the page like a "stand-alone" page I have no problem with that and the selection has inside the righe row.
The page has some other little problem when loaded using the ui:include.
Thank you very much.
Best Regards, Mario.
