Hi Alex, is this expected behaviour?
: (collect 'usr '+Pat *U 'doc *D) -(NIL) : (db 'usr '+Pat *U 'doc *D) -{Bg} I would expect 'collect' returning ({Bg}). Or could it be some problem with my ER schema? (class +Pat +Entity) (rel doc (+Ref +Link) NIL (+Doc)) (rel usr (+Ref +Link) NIL (+Usr)) Thank you, Tomas -- UNSUBSCRIBE: mailto:picol...@software-lab.de?subject=unsubscribe
