I see that there has not been any update for the possible Design Patterns within Mendix. Currently we have a requirement that there should be just one instance of an Entity across the whole application. Is there a way to ensure that one and only one instance of an entity is created and accessed across the application? There unintended creation of object should be prevented.
Great idea! See the Mendix Design Patterns blog of Andrej Gadjuk and have a look at https://mendixdesignpatter-sandbox.mxapps.io for the app MendixDesignPatterns, where we have examples of a strategy and a visitor.
Chris, If you feel you have a reusable service microflow, you should export it and save it. Then just re-import it for the next modeler design you need it for. The problem with producing a library like that is many people model their applications out in their own way.
