[cells-devel] can one make dependencies between models?

Hello, I am doing very basic cell-stuff, much like the ones in the doc folder: Not liking excel and its cousins, I am implementing spread-sheet like calculations in cells. My question: 1) Can I build two models (model1, model2) and specify that a slot in model2 depends on changes in some other slot in model1? 2) Related: can I change a slot specification in a model. For example from `c-in' to `c?'. I assume that I can, but I would have to re-initialize the model somehow. Correct? I am also very interested in the question posted just a few minutes ago. I would like to build an automated way of generating a GUI front end my cell models. Thanks, Mirko
