Sort in Rule Team Server uses alphanumeric values for priority instead of numeric values
Why do the rules not appear sorted by priority ?
The priority can be expressed not only as a numeric value, but also as an expression in the rule language that can use a ruleset variable (i.e. dynamic priority). For more information on dynamic priorities, see:
The section on how to set simple priorities among rules: http://publib.boulder.ibm.com/infocenter/brjrules/v7r1/topic/com.ibm.websphere.ilog.jrules.doc/Content/Business_Rules/Documentation/_pubskel/JRules/ps_JRules_Global482.html
The section on the priority keyword in the technical rule language reference: http://publib.boulder.ibm.com/infocenter/brjrules/v7r1/topic/com.ibm.websphere.ilog.jrules.doc/Content/Business_Rules/Documentation/_pubskel/JRules/ps_JRules_Global1894.html
If you are only using numeric values in your rule projects, the best way is to use priorities with the same number of digits.
In addition, you can also customize Rule Team Server to automatically add any number of zeroes to the left of each priority, and ensure that they all have the same number of digits.
To this effect, you must define a custom session controller that will modify the priority of a rule just before any change is committed to the database (i.e. when you click on "finish" while editing a rule). This is done by overriding the onCommitElement() method of the interface IlrSessionController.
