Of course your model (or group) have to have some UV data already othervise you would see just one dot in upper left corner of workspace. To assign UV data to model (or group) do what is writen at the begining of my post...
That dot is your whole model (all the wertices of it have the same UV coordinate=0,0) so if you want to select your model, just select that dot by fence selection or go to
Select>>>
All
hope it helps
