GWT's CellTable loading bar won't display while refreshing contents

سؤال
I do the following:
- Create the CellTable (loading bar displays)
- Put data in it (loading bar disappears, data appears)
I now want to:
- Clear data and show the loading bar
- Put more data in it (loading bar disappears, data appears)
Has anyone done this? I've tried a few methods but they seem like hacks and haven't worked.

In GWT trunk there is a revision r9687 just for your case, which sadly wasn't included in latest GWT-2.2 release:
Log message
Adding a LoadingStateEvent to CellList and CellTable so users can receive an event when the data is loaded. Now, LoadingState is a first class citizen (an interface so users can define their own loading state). Both CellList and CellTable now support setting a custom loading indicator Widget and a custom Widget to display when the table is empty.
