After the breakpoint rule is isolated, it is often helpful to copy the relevant logic into another Rulesheet for more focused testing. See the Rule Language Guide to ensure you have expressed your rules correctly. Be sure to review the usage restrictions for the operators 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 the product version used, and the set of Corticon files (.ecore, .ers, .erf, and .ert) that will enable us to reproduce the problem.
