In the TOC 2.1.1 (Robert Sheitlin's) in the code gallery when a group is ticked on then all layers in that group are turned on as well...the out-of-the-box 'Layer List Widget' has this bug fixed now in the 2.2 version. Any ideas on how to transfer that bug fix into Roberts TOC widget?
The 'Zoom To Make Visible' feature is pretty sweet!
