*" In "modern" GWT development you shouldn't have to ever call sinkEvents
(use addDomHandler)."*
*
*
CellTable and other Cell based widgets use the sinkEvents approach. Am I
missing something? Is that just an anomaly because of the
ultra-high-performance expected off of huge-data-rendering Cel
wealth.
(One could create a table from within Google docs)
