Binding seems to be unreliable with MVEL dialect and mulitple evals ------------------------------------------------------------------- Key: JBRULES-2482 URL: https://jira.jboss.org/jira/browse/JBRULES-2482 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-core (expert) Affects Versions: 5.1.0.M1 Environment: Windows 7, Sun JDK 1.6.0_17 Reporter: Chris DeLashmutt Assignee: Mark Proctor When using the MVEL dialect, a rule with multiple binds, and a chain of evals, the bindings seem to be incorrect. For example here is some DRL: rule "Modify Field Rule for Form: InterrelatedFieldsTestForm.fieldA (Set fieldA optional if values are in other fields)" when $fieldA: Field(id == "fieldA") $fieldB: Field(id == "fieldB") $fieldC: Field(id == "fieldC") (eval(ValidationFunctions.isChecked($fieldA)) or eval(ValidationFunctions.isChecked($fieldB)) or eval(!ValidationFunctions.isBlank($fieldC))) then ValidationFunctions.insertOperation(fieldOperations, new FieldOperation("fieldA",FieldOperation.OPTIONAL)); end If I put debugging statements in to the static ValidationFunctions methods, or if I put breakpoints in those same static methods, I see invocations using bound variables that don't match what I declared. For instance, I'll see isBlank called with what appears to be the contents of $fieldA. If I combine the evals into a single eval with each condition separated by ||. everything seems to function properly. I can't easily go back and change the syntax in my exisiting rules however, and the syntax I'm using seems to be valid based on my interpretation of the documentation. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
