Re: [rules-users] Guvnor web-based decision table not firing
Never mind. I was looking for a problem with Guvnor, but the problem was in one of the Conditions. The table rules fire. -- View this message in context: http://drools.46999.n3.nabble.com/Guvnor-web-based-decision-table-not-firing-tp4020644p4020645.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] Guvnor web based decision table
Hi, Just to make sure. I would like to migrate the attached excel decision table to Guvnor. Can you make a suggestion? Migrate or not migrate based on the current possibilities/features of Guvnor. Kind regards and thanks in advance.

Re: [rules-users] Guvnor web based decision table
Greetings: Jarek, Mark, Edson, Wolfgang and others are far better at the specific, in-depth details in Drools than myself. However, I did notice two things that called attention to themselves in the email below: (1) Priority (or specificity) should be used, if at all, sparingly. More than three levels of priority indicate a possibility that a procedural program is being done with declarative rules. Five levels and you definitely need to use Java or C++ or something else rather than a rulebase. (2) Global variables in a rulebase, as in Java or C or C++, should be avoided whenever possible. They are a death trap that has killed off many an excellent idea. Most vendors point these things out when they explain how to implement global variables and/or specificity. It's almost as bad (really close) as using a GOTO in BASIC. Yes, it's there. But don't use it. One other thing: External code should never change the value of an element being used by the rulebase in the condition part of the rules. If the datum is used by the action element it still MIGHT not be a good idea and should be used very carefully. However, returning a boolean is the normal use of external code that does not modify data - that's about the only SAFE way to use them. SDG jco This above all: to thine own self be true, And it must follow, as the night the day, Thou canst not then be false to any man.
