Hi all. In the Modeler>Modeler-only tools>Calculator I found several minor issues: * 'usingsingle' should be 'using single' * 'as follows:' is not follwed by any text * text in the box is not selectable. Should I open tickets? All the best. -- Paolo Cavallini - www.faunalia.eu Corsi QGIS e PostGIS: http://www.faunalia.eu/training.html
