I don't believe it sets a hidden variable when you clear an ROI (well, 
none that I can find anyways).  It calls this function:

function ROIRemoveAll()

and uses the ROIManager to handle states.  That being said it would be 
quite easy to modify this function so that you could set a hidden 
variable in your template.  Alternatively you could access the 
goCWCROIManager object to determine the state of an ROI through javascript.
