[OpenLayers-Users] WMS GetFeatureInfo not returning results

[Tobias Luetticke]

Hi there

Sorry for the late answer, but your reply was caught in the spam
filter.

I finally figured this one out, at least sort of. It must have been my
GeoServer that was messed up in some non-obvious way as the layer
preview did work on other systems. I reinstalled and now it works fine.
A case for the X-files, I'm afraid.
BTW, text/plain didn't change the fact that no data was coming back,
but instead of sending an empty table it presented a message that clear
and along the lines of "No data found".

Cheers
Tobias
