The present invention relates to systems and methods that provide automatic generation of user interfaces via creation of a class-based model. A system is provided that facilitates generating a user interface. The system includes a class component to generally define properties and methods associated with one or more interface actions. A service component parses the class to automatically generate all or a portion of a user interface from the interface actions. Push and Pull-type models can be provided to facilitate merging of actions from various classes such as provided by third parties or from existing component developments.
