Hi Folks, The Dumb ZPatterns example is updated. Now there is some more realistic object referencing going on, borrowing of code snippets between Specialists and suchlike. There is also more in the way of reasonable documentation, though everything is in flux, and it still doesn't resemble a truly completed product. I just feel the need to get things finished enough that I can stop thinking about them for a while. ;-) In particular there the ToDos now hold references to Doer and Deliverable, and no 'lists' are maintained. One thing I need to do is to have these references automatically 'fixed' when a 'referred to' entity is removed or modified in such a way that the link should be broken.... that's for the next version. If I'm not careful.. it won't be a 'simple' example anymore. There's got to be a line here somewhere (in the sand?). take care, -steve
