Hi,
the following capabilities have to be set, if
- PickTool.GEOMETRY_INTERSECT_INFO -
intersection tests are applied:
geometry_array.setCapability(GeometryArray.ALLOW_FORMAT_READ);
geometry_array.setCapability(GeometryArray.ALLOW_COUNT_READ);
geometry_array.setCapability(GeometryArray.ALLOW_COORDINATE_READ);
geometry_array.setCapability(GeometryArray.ALLOW_NORMAL_READ); (?)
Just try,
Marc
