[OpenLayers-Users] WMTSGetFeatureInfo on a Geoserver “Layer Group”

[RD Harles]

Hi,
I’m attempting to execute OpenLayers.Control.WMTSGetFeatureInfo on a Geoserver “Layer Group”.
It gives me a popup with information from ONLY one layer in the layer group.  Is it possible to get information from all layers in the group?
I thought setting “drillDown = true” would take care of it, but it doesn’t seem to work.
Any thoughts would be appreciated!
Thanks!
