Long time listener, first time caller here. I'd certainly echo everyone's sentiments- great work, keep it up, thank you-thank-you-thank-you-thank-you ...
Using the previous release, I've pretty much got your grid working as a JSF-wrapped component, with optional drop-and-drag and server-side state automatically synced. (I haven't pushed it live yet: imagine how much better this page will look with a scrolling Ext grid instead of the JSF default table: http://www.s-rod.com/tools/playerRanker.xhtml )
I'm considering switching my JSF component to use this alpha release, but before undertaking it, wanted to confirm that Drop 'n' Drag is supported in the new grid. I don't see GridDD in the downloaded source ... is DnD not yet in? To the previous source code, I've added small bits of code from the Grid DnD blog postings to generalize the capability; just generally-speaking, high-level, will that approach continue to work (with adjustments, obviously) with the alpha 1.0 release?
