Hi I'm using an expression to select dangle lines on a vector layer :
aggregate( layer:=@layer , aggregate:='count', expression:=id_graphe, filter:=intersects($geometry, end_point(geometry(@parent)))) - 1 = 0 or aggregate( layer:= @layer , aggregate:='count', expression:=id_graphe, filter:=intersects($geometry, start_point(geometry(@parent)))) - 1 = 0 It works fine in UI But with same data when I want to use this expression in Processing, selecting dangle lines fails (no errors, but 0 selected lines) I update expression in order to follow processing syntax an replace layer reference (@layer) by output alg (@Extraire_par_localisation_OUTPUT): aggregate( layer:=@Extraire_par_localisation_OUTPUT , aggregate:='count', expression:=id_graphe, filter:=intersects($geometry, end_point(geometry(@parent)))) - 1 = 0 or aggregate( layer:= @Extraire_par_localisation_OUTPUT , aggregate:='count', expression:=id_graphe, filter:=intersects($geometry, start_point(geometry(@parent)))) - 1 = 0 this without success. What is the right way to achieve that ?
