The VAModel is a pure Java-to-Java code generator for a Vaadin application. The model is defined in a Java structure where an application is defined by EntryPoints, each one with a hierarchy of APMComponents. Some components have also events that can be registered to any other component. All actions are delegated to a central class and some Java classes are automatically generated to simplify the development in a given component. The components that have more features are currently: Form Table Tree PopUp The generator creates classes annotated with @MTemplate that will not be overwritten by the next generation round. There is a working example project MyDocsGen as Proof Of Concept; a MongoDB instance on the standard ports needs to be running on the server to use it.
