There were a few kinds
of<br>dependencies:<br>1) Object Attribute dependency: The attributes of an object being used in<br>the conditional part of a rule<br> might be getting modified in the consequence part of another rule. We<br>wanted all such rules with each rule having its own dependency list.<br>2) Rule Salience based dependency. A rule having lower salience should be<br>executed only after a higher (if any) salience rule has already been<br>executed.<br>3) Dependency caused by a specific Rule flow. Rules in a ruleflow group<br>should be executed only if (if any) Split condition gets satisfied.<br>4) Agenda flow dependency (i.e., one agenda following another) <br><br> We could not find much support for this in the Drools API. Hence we<br>decided to write our own dependency generator. The tool we are writing<br>caters to first 3 dependencies. We might even handle the 4th one. <br> Since Drools is open source, we thought
of contributing our bit towards<br>its development. If the drools team wants I can happily work with them on<br>getting this functionality plugged in the Drools system.<br><br><br>Thanks<br>Siddharth<br>-- <br>View this message in context: <a href="http://www.nabble.com/Rule-Dependency-Generator-tp19821365p19821365.html" target="_blank">http://www.nabble.com/Rule-Dependency-Generator-tp19821365p19821365.html</a><br>Sent from the drools - dev mailing list archive at Nabble.com.<br><br><br><br>------------------------------<br><br>Message: 7<br>Date: Tue, 4 Nov 2008 13:24:48 -0800 (PST)<br>From: mellster <<a ymailto="mailto:mellster2000@yahoo.com" href="/mc/compose?to=mellster2000@yahoo.com">mellster2000@yahoo.com</a>><br>Subject: Re: [rules-dev] M2 Guvnor Tomcat Deployment Issues and<br> Resolutions<br>To: <a ymailto="mailto:rules-dev@lists.jboss.org"
