Oops, sorry for the confusion! A month or so ago I noticed that "app/er.l" was not correct :-( The current "testing" release contains the fixes. The above line must be > (rel ord (+Dep +Joint) (itm) pos (+Ord)) # Order '+Dep' takes a list of "dependent" relations, (itm) in this case. This means, whenever the 'ord' relation of '+Pos' is cleared, so will automatically be the 'itm' relation. Clearing the 'itm' is necessary here, in order to remove this position from the '+Ref' index. Otherwise, for example, a report listing all sales for this item would show incorrect results. > (class +Cat +Entity) > > (rel nr (+Need +Key +Number)) > (rel nm (+Ref +String)) > (rel it (+List +Joint) cat (+It)) > > (class +It +Entity) > > (rel nr (+Need +Key +Number)) > (rel nm (+Sn +Idx +String)) > (rel cat (+List +Joint) it (+Cat)) > > (gui '(+E/R +Chart) '(it : home obj) 3 '((This) (list NIL This NIL)) > cadr) > (<table> NIL NIL '((btn) NIL (btn)) > (do 6 > (<row> NIL > (gui 1 '(+ChoButton) '(choIt (field 1))) > (gui 2 '(+Obj +TextField) '(nm +It) 40) > (gui 3 '(+DelRowButton)))) > (<row> NIL NIL (scroll 6))) Looks good, though I haven't tested it. > I would like to be able to reorder items +It in a category +Cat. > What else do I need to do except adding (gui 4 '(+BubbleButton)) ? Nothing I can think of at the moment (except, as you know, the normal administrative things like changing 3 -> 4 in the +Chart line). > Is +Dep and (art) related to row reordering? No, as changing the line does not cause any removal of relations. Cheers, - Alex -- UNSUBSCRIBE: mailto:[EMAIL PROTECTED]
