I create an ordered selection from a collection by doing this: ARRAY LONGINT($ids;0) COLLECTION TO ARRAY($collection;$ids) QUERY WITH ARRAY([table]ID;$ids) ORDER BY FORMULA([table];Find in array($ids;[table]ID)) -- Grüße/Regards, [heubach-media] | Christian Sakowski [email protected] Tel: +49/(0)40/52 10 59-23 > Am 18.10.2018 um 14:14 schrieb Peter Bozek <[email protected]>: > > > > On Sat, Oct 13, 2018 at 10:29 PM Christian Sakowski via 4D_Tech > <[email protected]> wrote: > > > > > > > like: > > $object.myIDs:=$entitySelection.toCollection("ID“).extract(„ID“) > > new process(…;$object) > > > > and in the new process just create the new entity selection: > > > > ds.Table.query(„ID IN :1“;$object.myIDs) > > > I tried simpler (but I believe identical) solution: > > $collection:=$selection.ID > $err:=New process("aaExecuteProcess";0;"test";$collection) > ... in the process > > $selection:=ds.Table.query("ID IN :1";$collection) > > There are several problems with it: first, I did not find a way how to do a > shared collection from selection, there is no "New shared collection form > selection".
