[Chameleon] ungrouped layers and legendtemplate

[Ken-ichi]

Hi all.  I feel like this is a problem I have solved in the past but I 
just can't seem to figure it out: my layers in a map file are organized 
into GROUPs, and I have an HTML legend template that works fine with the 
LegendTemplate widget.  However, when I have a layer that isn't a part 
of a group, it disappears whenever the map is updated (update, zoom, 
pan, whatever).  I was hoping to use ungrouping layers as a way of 
hiding them from the legend while still displaying them on the map.  Is 
Chameleon actually looking to some list of layers generated by 
LegendTemplate when it draws an updated map?  Is there a better way to 
effectively "hide" some layers from the legend in Chameleon?

Thanks in advance.
