I was very excited to see that feature but unfortunately it doesn't offer the same selection mechanism as does the old yui-based implementation. CTRL+Shift doesn't seem to be supported. Well, I need to have a closer look at this component and see if we can work with it. All the fancy features are nice to have but what we really needed was a simple datatable with this very user-friendly excel-like selection feature offered by the yui datatable component.
I guess you have decided to make this move with good feedback from the community so maybe I should not complain.
Anyhow, the situation isn't as bad as in JSF 1 times as it now seems possible to implement custom components without being a magician. I thought about the jqueryUI selectable which would even provide a better usability than the yui datatable. What about Github?
I think Richfaces is really trying to involve the community in providing new components.
Thanks for your work.
