The KitchenSink Grouped List works but it's not using a Store. I can't seem to get my Grouped List to work with a Store. If I remove "grouped:true", the list displays but sans grouping and index bar. I suspect that either I need to configure the store differently OR that there's a bug in the PR1 release.

Has anyone gotten a Grouped List to work WITH a Store?

Also, what are the "groupers" and "groupField" Store parameters for? I've tried with and without them and neither case works.
