I'm trying to use CQL but I guess I do it wrong because I get pink layer in return and error in geoserver :
Binary geometry filter, but first expression is not a property name? (it's a class org.geotools.filter.LiteralExpressionImpl) java.lang.IllegalArgumentException: Binary geometry filter, but first expression is not a property name?
This is how I try to do the DWITHIN (get all lines at 200 meter from buildings)
What am I doing wrong ?
