I'm having a problem trying to convert an older (GWT 2.1) app to

use the new DataGrid class. The app was successfully upgraded to

GWT 2.4 months ago, but this is the first time we are trying to

introduce new 2.4 features.

When I run in development mode, the GWT Development Mode window

logs the following:

00:00:32.151 [WARN] For the following type(s), generated source was never committed (did you forget to call commit()?)

00:00:32.151 [WARN] com.google.gwt.user.client.ui.NativeHorizontalScrollbar_NativeHorizontalScrollbarUiBinderImpl

Meanwhile an exception is caught in the client:

java.lang.ExceptionInInitializerError

at com.google.gwt.user.client.ui.CustomScrollPanel.<init>(CustomScrollPanel.java:196)

at com.google.gwt.user.client.ui.CustomScrollPanel.<init>(CustomScrollPanel.java:233)

at com.google.gwt.user.cellview.client.DataGrid.<init>(DataGrid.java:534)

at com.google.gwt.user.cellview.client.DataGrid.<init>(DataGrid.java:525)

Line 196 of CustomScrollPanel.java reads:

setHorizontalScrollbar(new NativeHorizontalScrollbar(hResources), AbstractNativeScrollbar

.getNativeScrollbarHeight());

This seems to indicate that the exception is tied to the

warnings, but I don't know what it all means.

I think this might be the underlying problem:
