Re: Garmin Communicator API

Stephen,

You're most likely going to need to use the $wnd or $doc variable
within your JSNI code as the Garmin JS is not loaded into the same
area as GWT code (http://code.google.com/webtoolkit/doc/1.6/
DevGuideCodingBasics.html#DevGuideJavaScriptNativeInterface)

i.e. var display = new $wnd.Garmin.DeviceDisplay("garminDisplay",
{........
