[Chameleon] N- LegendTemplates and cwcjsapi events

[Brent Lund]

OK - I was hoping to avoid a hack, but will do.

One legend is a typical legend. The second contains related links and
graphics (photos) which depend on the layer(s) selected.  Since its not
really a legend I may create a new container.

Thanks,
bl

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?

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