WMS GetLegendGraphic - Raster, Annotation AND GROUP

[Bart van den Eijnden]

Hi,

there was a discussion about the GROUP layers and GetLegendGraphic in bug
653, comments 9-12:

http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=653

I can't remember what happened to my setup with GROUP layers, but it
shouldn't give back a red cross :), I will check with version 4.4 to see
if I can reproduce your problem.

Best regards,
Bart
