Let's say we have an entity Concert and an entity ConcertLocation and the model is such that a Concert would reference a ConcertLocation (shared ManyToOne association).
In a create dialogue for the Concert entity I would like to offer the possibility to create a new ConcertLocation item if the desired location is not found in the dropdown or select box. This could for instance be by displaying a "create new location" icon next to the dropdown box for locations or anything else, which would then open another modal on top of the create dialogue to create that new ConcertLocation. Once the new ConcertLocation has been created it should then appear in the list of available locations in the Concert create dialogue. How would I go about this in Apache Isis? I haven't found anything of the kind in the kitchen sink or the todo app or any other examples available. Thanks and regards, Martin
