Thanks so much, I am still using 1.4.1 which has a lot of hacks and fixes and are slowly testing 1.4.4 so that I can upgrade to the latest.
Aother really neat feature would be to allow a sub-group (just one) and then allow the groupFormatter to be able to access the groupField and the subGroupField so that it could do something like this:
groupFormatter: function(grp, sub){
return grp +' - '+ sub;
}
:-)
