With this new version 3.6.2 it is now possible to generate code from activity diagrams created with UModel. UModel has support for the basic activity elements such as actions, init - and final nodes.

The microwave oven model microwave_handbook_umodel was extended to show how to use activity diagrams together with state machines in UModel. The example uses a selftest function called at initialisation of the state machine. If the selftest fails the machine enters an error state. The following figures show the extended oven model and a very simple selftest activity diagram.

Download the latest version and give it a try. Activity modelling is a very useful extension to state machine modelling!

Have fun!
