Once the breakpoint rule has been isolated, it is often helpful to copy the relevant logic into another Rulesheet for more focused testing. Refer to the Rule Language Guide to ensure you have expressed your rules correctly. Be sure to review the usage restrictions for the operator(s) in question.
If, after isolating and verifying the suspicious expression syntax, you are unable to fix the problem, please call Progress Corticon Technical Support. As always, be prepared to send us a) the product version used, and b) the set of Corticon files (.ecore, .ers, .erf, and .ert) that will allow us to reproduce the problem.
