[Mapserver-users] getFeatureInfo on dynamic layer - empty exception

[Frieso ter Haseborg]

Hi Debbie,

from the PHP/MapScript for dynamic layer creation you shared with us I
learned, that you're doing getFeatureInfos against a php-created layer. 

Does the error description below sound similar to anything you ran
against during your development? Or are there any
configuration-differences in the mapfile compared to your approach?

Since there was low feedback from the list on this , I hope you could
give me a hint.

TIA,
Frieso
