[Chameleon] LegendTemplate Widget - Combining checkbox and radio button layer selection

[Jessica Deegan]

Greetings List,
 
I am using an instance of LegendTemplate to control layer selection
via a Mapserver HTML template.
 
My problem is that I want to combine the use of both checkboxes
(for overlay kinds of layers) and radio buttons (for backgrounds). 
I have metadata in the mapfile that indicates this status. (a
snippet of code from the template is below)
 
Unfortunately, because the name element is the same for both radio
and checkbox inputs, a selection of a radio button will turn off all
the checkboxes (problem is limited to Internet Explorer).
 
I can't seem to track down where "legendgroupname[]" has roots, as
I initially duplicated the legend widget and tried to rename the
variable in a new widget.

Any advice is much appreciated!
Best regards,
Jessica
