I installed PostgreSQL and PostGIS and created PostGIS layers in GeoServer. But when i want to change geometry in QGIS via WFS it drops an error:
": Error performing insert: java.lang.String cannot be cast to com.vividsolutions.jts.geom.Geometry"
I've read the type of the geometry isn't OK, eg. 'linestring' and 'multilinestring' How could i solve this problem to update my layers?
