RE: addEventlistener question

I'm still getting the same response. In my "screen" class, I identify
the events of interest as:

public HistoricalVosDataScreen() {
	specifyLocalEventInterests(getHistoricalVosDataFactory,
GetHistoricalVosData.class);
	specifyLocalEventInterests(renderHistoricalVosDataFactory,
RenderHistoricalVosData.class);
	specifyLocalEventInterests(selectByRoadwayFactory);
	specifyLocalEventInterests(selectByStationFactory);
}

Is this correct?

Yes! The problem you are having is that ApplicationGateway doesn't know
where to deliver the event. The easiest way to do this is via an
event-gateways.xml file, like this:

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

<assemble>
    <event-gateway
class="org.enhydra.barracuda.core.event.DefaultEventGateway">
        <event-gateway class="com.atmr.atmreports.screens.Login"/>
        <event-gateway class="com.atmr.atmreports.screens.Home"/>
        <event-gateway class="com.atmr.atmreports.screens.Businesses"/>
    </event-gateway>
</assemble>

Now, the way this get's invoked is from within web.xml...where the
ApplicationGateway is declared, you provide a reference to your
event-gateways.xml like this:

        <init-param>
            <param-name>AssemblyDescriptor</param-name>
            <param-value>/WEB-INF/event-gateways.xml</param-value>
        </init-param>

If you look in the Barracuda web.xml, you should see an example of this.

Fix that, and you should be in business!
