[maplab-users] MapEdit preview problems

um.  I think this is a problem with the legend template.  Is your 
template value in the LEGEND object pointing to a real legend template 
file or is it a fake file?

If it is a real file, then that file defines the references to images 
and javascript functions.  The mapedit preview uses the legend template 
defined in the map file if possible.  This was to allow for a 'preview' 
of the legend template but in hindsight this was probably not a good 
idea since the legend template can define functionality as well.  I 
think that we will remove this so that mapedit always uses it's own 
legend template to make sure that it works.
