Hello,

  I'm facing some problems when trying to update an ExtendedTableDataModel. In fact I'm trying to refresh a list of flights after adding a new one.

When I save the new flight, it is added in the database but the extendedDataTable is not refreshed.

So the code in my jsp for refreshing an extendedDataTable is:

             <a4j:commandButton action="#{flightsController.save}" value="Save"
                    reRender="formTableFlight">
                </a4j:commandButton>

And the 'save' method in my controller :

public String save() {
        for (Company c : companies) {
            if(companyName.equals(c.getName()))
                    company = c;
        }
        flight.setCompany(company);
        flightsService.add(flight);
        flights.add(flight);
        form.setRendered(false);
        addCommand.setRendered(true);
        return null;
    }

The extendedDataTable is declared as follows :

<h:form binding="#{flightsController.formTableFlight}"
                id="formTableFlight">

                <rich:extendedDataTable
                    value="#{flightsController.extendedTableDataModel}" var="flight"
                    selection="#{flightsController.selectionFlight}" id="tableFlight"
                    sortMode="single" selectionMode="single" width="500px"
                    height="200px">

                    <f:facet name="header">
                        <h:outputText value="Flight" />
                    </f:facet>

                    <rich:column sortable="false" label="Code" id="col_code">
                        <f:facet name="header">
                            <h:outputText value="Code" id="code" />
                        </f:facet>
                        <h:outputText value="#{flight.id}" id="flight_id" />
                    </rich:column>

                    <rich:column sortable="true" label="Departure" id="col_departure">
                        <f:facet name="header">
                            <h:outputText value="Departure" id="departure" />
                        </f:facet>
                        <h:outputText value="#{flight.departure}" />
                    </rich:column>

                    <rich:column sortable="true" label="Departure" id="col_destination">
                        <f:facet name="header">
                            <h:outputText value="Destination" id="destination" />
                        </f:facet>
                        <h:outputText value="#{flight.destination}" />
                    </rich:column>

                    <rich:column sortable="false" label="actions" id="col_actions">
                        <f:facet name="header">
                            <h:outputText value="Actions" id="actions" />
                        </f:facet>
                        <h:panelGrid columns="1">
                            <h:commandLink value="delete"
                                action="#{flightsController.delete}">
                                <f:setPropertyActionListener
                                    target="#{flightsController.flight}" value="#{flight}" />
                            </h:commandLink>
                        </h:panelGrid>
                    </rich:column>
                    <a4j:support reRender="tableStep"
                        action="#{flightsController.takeSelection}"
                        event="onselectionchange" id="table_takeSelection" />
                </rich:extendedDataTable>

The extendedDataTableModel is initialized by this code :

private List<Flight> flights = flightsService.getFlights();

public ExtendedTableDataModel<Flight> getExtendedTableDataModel() {
        if(extendedTableDataModel == null) {
            extendedTableDataModel = new ExtendedTableDataModel<Flight>(new DataProvider<Flight>() {
                /**
                 * 
                 */
                private static final long serialVersionUID = -776297803803735490L;

                public Flight getItemByKey(Object key) {
                    for(Flight c : flights){
                        if (key.equals(getKey(c))){
                            return c;
                        }
                    }
                    return null;
                }
                public List<Flight> getItemsByRange(int firstRow, int endRow) {
                    return flights.subList(firstRow, endRow);
                }

                public Object getKey(Flight item) {
                    return item.getId();
                }

                public int getRowCount() {
                    return flights.size();
                }                

            });
        }
        return extendedTableDataModel;
    }

Thanks for help
