I am quite excited about gxt 3.0. As I read your are planning a new widget called PivotGrid. I would really like to know if this is still planned (its not in the preview I guess) and what features it will have.
Also I would really like to have a very rough estimate when this widget will be available. Depending on the release date I would decide to do it on my own or not.
Or does anyone know about an existing GWT pivot table implementation? Has anyone implemented a gwt pivot table and give a rought effort estimate for a version with basic features (column, row and datafields).
