Hallo

Habe mir für einen Prototyp das Zope3 package lovely.relations angeschaut. Dabei bin ich auf ein Problem bei Backreferences ('RelationPropertyIn') gestossen. s.u.

Konnte dies wie im Attachment zu sehen beheben.

Als Autor des Package ist jemand namens jukart angegeben. Bitte entsprechend weiterleiten, danke.

Ansonsten ist das package eine tolle Sache! Kompliment.

Gruss, Katja

--------------------

Beim Setzen einer Backreference wurde folgender Fehler geworfen:

backrefs = RelationPropertyIn(relatedFilesManager)

Als Widget wird ein modifiziertes OrderedMultiSelectWidget verwendet.
