I have an HTML legend template file that works wonderfully in MapServer 4.4
and below. However when using MapServer 4.6 and above my legend breaks. I
have thoroughly searched and tested for other possible problems but I have
concluded that the problem must lie somewhere in MapServer. Either
MapServer 4.6 and above reads HTML Legend template files differently than
older versions, or this is a bug in MapServer 4.6 and above. MapServer 4.6
and above handle the legend well when the mapfile contains a few layers.
But when the number of layers gets large (~10-15), the legend file's code is
never even entered. The CGI legend tag in my HTML file is simply skipped.
I have included my template file below. I am fairly desperate so any
thoughts are helpful. I would like to move to MapServer 4.8 but need the
legend to work first. Thanks.
