Hi'ya..... been wanting this kinda view for ages [smiley=cry.gif] ... a couple of modelling apps ( all now in the IBM camp, so destined for Java only ) did state chart animation.
You can get Squence diagrams from executing code, but these are not co-related to any you might have in your model... so youre rather reduced to doing it manually. I vaguely remember an addin that coverted between Sequence and Colaboration (Communication Summary v2'ishie) diagrams, but seems to have died.
I think the Realtime MDG thingie, is going to include code-generation for state charts... so we might except some 'animation' of statecharts. But even tho the 'questions on reporting' is down a lot, thats more due to Sparx addressing requests than users moving away from the printed static presentation of model content.
Activity diagrams are usually pitched a bit above operation flowcharting, so there is unlikely to be an automated method of animating Activity diagrams anytime soon. Even if you could provided an activity profile for your choice of 'Implementation Language (C# for example).
I would very much like to know how you envisioned using this kind of facility... I don't know enough about the EA addin interface or code templates, but I would have thought some kind of signalling from runtime to EA would do some of what we wanted to do.
If we was really ambitious we'd be asking for UML .Net Compiler and not bother with other surface languages ( we is Analysts and Designers not mere programming tapers )

Perhaps.
