[Chameleon] Hawaii Demo

thanks.  I think the xml legend with DHTML is what I am looking for.  Is 
there any special way to add individual layers to the legend instead of just 
groups?  I tried modifying the sample_themes.xml and sample_renderer.html by 
adding a <layer param .../> in the global section of the sample_themes and a 
repeat layer section:

[repeat layer]
    <td width="20">&nbsp;</td>
    <td width="20">[layer_input]</td>
    <td><span class="label">[layer_name]</span></td>

within the repeat group section of the sample_renderer

This causes errors:
Notice: Undefined index: layer in 
C:\ms4w\apps\chameleon\htdocs\TemplateProcessor.php(236) : eval()'d code on 
line 163

I'm also wondering if it is necessary to have a radio button like in the 
other legends to indicate which layer is active?  If this is selected, this 
means it is the layer which will be queried if you use the identify button 
right?  If there isn't a button to select, what gets queried?
