[Chameleon] Legend Template Bug?

When working on the legend for my map project, I have noted a strange
behavior. Unfortunately, my limited experience with the scripting system
does not allow me to determine if this is a bug, or if I am doing
something I shouldn't be.
I am working with the LegendTemplate widget in Chameleon, and have used
the example code from legend_template.html and additional code to
display grouped layers. I've pulled out everything and only added in
basic code to display legend groups, and the behavior still presents
itself. At the end of this email is my current code.
The problem with adding the leg_group_html code in, is that upon zooming
to a certain scale on my map, the layers which are not visible in the
legend (yet are visible on the map), disappear! This seems to be a
catch-22... I need to hide some layers from the legend, but if they are
not given names or groups in the map file, the legend turns this
"hidden" layer off!
I'm uncertain if this is a behavioral problem with Chameleon, or some
weirdness with the legend script, any ideas?
