[Mapserver-users] getFeatureInfo on dynamic layer - emptyexception

Hi Debbie,

thanks for your response.

Looks like the layer-name is not cause of the problem, with a more
qualified term or simply any other "non-reserved-word"-name it doesn't
work either.

Whoops! Sorry, these are remains of my desperate trials to isolate the
problem. I had the idea that perhaps getFeatureInfo-requests would only
be executed on non-raster layers. But there's no difference in this
special problem when changing the layer-type: in both cases the php
simply isn't called at all.

TIA,
Frieso
