GWT paging widget

I'm looking for a GWT common purpose paging widget. So far I have found GWT widget library and the Google Incubator widgets. Is there any other free (possibly open source) widget library implementing a paging behavior.

What is GWT widget?

You construct user interfaces in GWT applications using widgets that are contained within panels. Widgets allow you to interact with the user. Panels control the placement of user interface elements on the page.

GWT 2.1 now ships with paging widgets.

You found the two major ones. The Google Incubator widgets might be a good bet, because the intention is for these to eventually make it into the main library. In general the GWT widget library widgets tend to be fancier, but the GWT incubator library widgets tend to be more modular and also more robust across more web browsers.
