For documenting or designing the sequencing behaviour of, say, Agenda Groups you can use something old-fashioned like flow charts. It's generally accepted that rule based programming should best avoid dependency on "flow", i.e., any mechanism exercising explicit control over the time where rule groups are active. One notable exception is the requirement for (relatively large) rule groups being applied in a sequence of stages. Also, certain rule patterns warrant sequencing of small rule sets, which is best achieved by "control facts"; occasionally one might use two or three levels of salience to enforce sequencing. <br>

That is what I am looking for during the design phase. I have many ways to find rule execution at run time. But, I want to visualize the entire flow during design time.<div><br><div class="gmail_quote">On Mon, Jul 2, 2012 at 11:47 PM, Wolfgang Laun <span dir="ltr"><<a href="mailto:wolfgang.laun@gmail.com" target="_blank">wolfgang.laun@gmail.com</a>></span> wrote:<br>
