Hi Wouter, omitting the state charts is OK, but even if you replace them by activity graphs, the distinction between the macro workflow and the micro event handling should be visible. The idea behind that is that one activity in the workflow is like a component with defined inputs and outputs: a sequence of activities can be rearranged without breaking the internal event flow of each activity itself.
When a guard evaluates false, there must always be an "else" guard. Model constraints like that are perfect examples for OCL! Somebod was already dreaming about the inclusion of an OCL parser in AndroMDA - who was that? Cheers...
