Ok, I'm now using only one LegendTemplate widget.   All is well -
almost...

I've been testing with firefox.   When I checked the application in
Internet Explorer I found that the LegendTemplate widget does not update
in JSAPI mode. 

I'm using Chameleon 2.2.1

Hi,

The LegendTemplate widget is designed to support only one Legend in the 
page in JSAPI mode. You may be able to hack it to support multiple, but 
you need to be comfortable with JS code. Is there a reason why you 
display the legend twice in the same page?

Julien

PS: 34 is the widget ID. It's set in the widget code around line 316.
