Question about optionality in one-to-one relationships

Hi, Can someone help me understand something? I’m trying to model a one-to-one relationship between two entities but I can’t seem to get the relationship to be optional. In my specific case I need to model an entity representing shipments with a postal service. Each shipment needs to have a nu

mandatory by design. Wouldn’t it be more appropriate to have a flag in the modeler with which to mark relationships as mandatory for these specific cases? Is there an easy workaround? Regards, Riccardo > On 11 Jan 2024, at 00:02, Riccardo De Menna wrote: > > Hi Michael, > > I’

Can I populate the Java Type popup in the Modeller with my custom types?

Hi, Is there a way to show my custom extended types in the popup for the Java Type column in the modeller? Typing the full package name + class every time is error prone and slow. I end up doing it on the .xml model but the GUI would make it easier. regards, Riccardo
