Confirmed -- fix incoming! > Is this correct, are expressions not available all over QGIS within the > expression builder? Some expression functions/variables are "context dependent". E.g. is_layer_visible doesn't make any sense in expressions which aren't directly associated with a map. So the function won't be available as for expressions used as a field default value, or for a layout text label (since the layout may have multiple maps, each with a different layer set, and a label isn't linked to any map item in particular!). > And how can I get this expression working for the print composer as well? Wait for 3.4 ;) Nyall _______________________________________________ QGIS-Developer mailing list [email protected] List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer
