[Geomoose-users] can't show legends

[Devon Piernot]

In this case, I'm trying to show one legend item for all three classes, 
so I commented out two of them.  After digging around all of my 
different mapfiles more, it looks like there is a problem with the 
legend for any class in my mapfiles where there is a CLASSITEM and 
EXPRESSION. This seems to be why layers with no CLASSITEM and EXPRESSION 
(such as the "Post Offices" layer) show a legend and why the "Political 
Boundaries" layer only shows one legend item and then quits when 
EXPRESSION is used.

Any ideas why this is a problem?
