cf8 includes a function ColdFusion.Window.getWindowObject('windowname'),
which can be called in regular js (not in cfscript), and will give you
access to its underlying ExtJS object and all its properties and
methods, which you can then manipulate as you like. see extJS website
or the docs included with cf8 (inside the CFIDE\scripts\ajax\ext\docs
folder on Win install) for more info.
