[OpenLayers-Users] Problem with WMSGetFeatureInfo erroring out

[Stephen Woodbridge]

OK, part of the problem is solved I added to the matadata:

'wms_feature_info_mime_type' "text/html"

which fix the error, but now I get back what looks like image map of the 
features which is not what I was expecting.

I currently have TEMPLATE "dummy" in my layers, do I need to create a 
real template for each layer? I thought that this was supposed to return 
GML with something like COL_NAME = col_value for each of the columns.
