  when you reference cell, it looks for attribute called cell not a  
template. cell() does that.

AW 1.3b I think allows you to specify what the test rig looks like;  
otherwise you can't really tell it how to load the template group. do  
remote debugging instead of trying to launch the debugger directly  
from AW.
