I am using gwt-linux-1.5.2 and gwt-maps-1.0.0 with some very simple
Java code:
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.ui.RootPanel;
import com.google.gwt.maps.client.MapWidget;
import com.google.gwt.maps.client.geom.LatLng;
public class MainEntryPoint implements EntryPoint
{
private MapWidget map;
public MainEntryPoint(){ }
public void onModuleLoad()
{
map = new MapWidget( LatLng.newInstance(53.188245,-2.558616),
12 );
RootPanel.get().add( map );
}
}
When using GWTCompile, all seems well. When using the shell (with
exactly the same classpath as compiling), I get:
java.lang.AssertionError: Backing JSO missing imported function

I have tried changing the order of the jars but, as I expected, this
makes little difference. I ha ve checked the source code in
com.google.gwt.maps.client.MapWidget.java finding:
public boolean isScrollWheelZoomEnabled() {
return MapImpl.impl.scrollWheelZoomEnabled(jsoPeer);
}
It gets a little confusing at this point. MapImpl is an interface
with:
MapImpl impl = GWT.create(MapImpl.class);
.
.
com.google.gwt.maps.client.impl.MapImpl.java and find:
boolean scrollWheelZoomEnabled(JavaScriptObject jsoPeer);
Anyway, why is the GWTCompiler happy but GWTShell complaining and how
do I go about fixing this?
Many thanks
