Link: Added: This issue is related to JBRULES-2066 Fix in place. For documenting this in the Release Notes, can you please confirm the following and fill in the missing information. Dot point explanations are fine:
The CAUSE (what was actually broken)
*
CONSEQUENCES of the bug (how it impacts users.)
* During the execution of test scenarios, the following error message could appear under certain circumstances:
2009-04-17 15:31:28,691 INFO [STDOUT] ERROR 17-04
15:31:28,690 (ServiceImplementation.java:runScenario:1875)
org.drools.RuntimeDroolsException: Exception executing
predicate
org.drools.base.mvel.MVELPredicateExpression.
* This error message was not considered helpful to debugging as it lacked information.
The FIX (what was changed to eliminate this bug) and
* toStrings() has been added to the MVEL
RESULTS of the fix (what now happens for users.)
* The expression text is now displayed as part of the error message.
* This is in order to provide the troubleshooter with more helpful information.
We are still awaiting the outstanding information for the Release Notes on this one. Please provide it as soon as possible. Thanks. added to the 5.0.CP01 release notes as resolved: JBRULES-2066 Some of the error messages returned by MVEL rules during the execution of test scenarios where not very usable. The toStrings() method has been added to the MVEL so the error messages can include the expression text. |
Date of First Response: 2009-09-10 02:10:57 securitylevel_name: Public With Guvnor 5.0.0.CR1 it seems that I have produced an error in a decision table which only appears during test scenario execution. However the error message given in the browser (and on the console) is not very helpful: {code} 2009-04-17 15:31:28,691 INFO [STDOUT] ERROR 17-04 15:31:28,690 (ServiceImplementation.java:runScenario:1875) org.drools.RuntimeDroolsException: Exception executing predicate org.drools.base.mvel.MVELPredicateExpression {code} As far as I know it's possible to extract the actual expression from MVELPredicateExpression and it would be nice if this gets printed so that users have a chance of fixing the problem. ;-)
