[basex-talk] Using geo module in BaseX GUI 7.7.2

Hi, when I want to use the geo functions out of the GUI, I get the error " [XPST0017] Function v not implemented." What could be possibly wrong? What I did: 1) enable geo module through Options->Packages->Install... 2) chose etc/modules/geo.xqm 3)In the Editor window, took an example from the Wiki http://docs.basex.org/wiki/Geo_Module import module namespace geo = "http://expath.org/ns/geo"; declare namespace gml='http://www.opengis.net/gml'; let $point := <gml:Point><gml:coordinates>1,2</gml:coordinates></gml:Point> return geo:dimension($point) Is there anything else to consider? As far as jvisualvm says, the jars such as basex-api.jar and jts-1.13.jar are on the classpath. Any ideas? Thanks, Nathan
